Taban Mes Iranian Company, as one of the specialized suppliers of semi-finished copper products in Iran, offers various copper sheets, copper strips, and copper busbars in different sizes, alloys, and brands. Copper is the third most widely used industrial metal after iron and aluminum, and due to its high electrical and thermal conductivity, corrosion resistance, and ductility, it has a wide range of applications in industries. The company, by leveraging a network of reputable domestic manufacturers (such as Shahid Bahonar Copper Industries of Kerman and Khavarmas) and supplying leading European brands (including KME, Aurubis, and Wieland), meets the needs of industries for high-quality copper. The offered products have a minimum copper purity of 99.9% and are manufactured in accordance with global standards; therefore, in terms of technical features and quality, they are competitive with international counterparts. Below, the specifications of each product (sheet, strip, and copper busbar) are presented separately.
Copper sheet is a flat product made from pure copper or copper-based alloys, produced as flat sheets or coils. With exceptional electrical and thermal conductivity, excellent flexibility and formability, and strong corrosion resistance, copper sheet is one of the most widely used metallic products in industry. After steel and aluminum sheets, copper sheet holds a significant position due to its unique properties. It is available in various thicknesses and sizes and is even popular in decorative applications thanks to its attractive and stable color. Taban Mes Iranian supplies copper sheets in various grades and dimensions from reputable domestic producers such as Bahonar Copper and Khavarmes, as well as top European brands like KME, Aurubis, and Wieland, with a minimum purity of 99.9%.
• Electrical & Electronics: Conductive parts in electric panels, switches, connections, transformers, and bus ducts.
• Heating & Cooling Systems: Heat exchangers, radiators, pipes, and tanks in HVAC and refrigeration.
• Architecture & Construction: Building facades, roofing, gutters, and architectural details.
• Automotive & Transportation: Radiators, brake pads, and electrical components in rail and aviation.
• Other industries: Industrial cookware, musical instruments, coinage, and artistic applications.
Copper sheets are produced in several main grades depending on their chemical composition and the presence of alloying elements. The most important types of industrial pure copper alloys used in copper sheets include:
• TPC Copper (Tough Pitch Copper or Cu-ETP): This includes electrolytic copper with a minimum purity of 99.9% and a small amount of oxygen (around 0.03%-0.05%). Known as electrical copper, it has very high electrical conductivity (minimum 100% IACS) and is ideal for sensitive electrical applications. TPC copper sheet offers good hardness and strength, but due to the oxygen content, caution is needed in hydrogen gas soldering and welding (risk of hydrogen embrittlement).
• DLP Copper (Deoxidized Low Phosphorus – Cu-DLP): An alloy containing at least 99.9% copper and around 0.004% to 0.015% phosphorus. The small addition of phosphorus removes residual oxygen and improves solderability and weldability without significantly compromising conductivity. DLP copper has excellent formability and bonding capability, with conductivity slightly less than ETP but higher than DHP.
• DHP Copper (Deoxidized High Phosphorus – Cu-DHP): Contains a minimum of 99.9% copper and about 0.015% to 0.04% phosphorus. This alloy is fully deoxidized and offers complete resistance to hydrogen embrittlement, making it ideal for welding and brazing. DHP copper is more flexible than ETP and effective in deep forming processes. Due to phosphorus, its electrical conductivity is slightly lower (about 85–90% IACS), but still suitable for many applications.
• Tin Bronze (Cu-Sn) or Phosphor Bronze: A category of copper alloys containing a percentage of tin (typically 5%–10%) and a small amount of phosphorus. While most common copper sheets are made from pure copper, CuSn alloys like CuSn5 or CuSn10 are used in specific applications where higher strength and spring properties are required. These alloys offer higher yield strength and wear resistance, used in springs, connectors, and mechanically stressed electrical parts.
• Other Special Alloys: Upon customer request, special alloy sheets such as silver-bearing copper (e.g., CuAg0.1P) or chromium-zirconium copper (CuCrZr) can also be supplied. These materials have higher mechanical strength and are used in applications like welding machine molds, continuous casting plates, and cases where both conductivity and hardness are needed.
The copper sheets supplied by Taban Mes Iranian are manufactured in accordance with international standards such as ASTM B152 (Standard Specification for Copper Sheet and Plate) and DIN EN 1652, both in terms of chemical composition and mechanical properties. The high copper purity (minimum 99.9%), along with strict control over impurities and alloying elements, ensures excellent electrical and thermal conductivity, uniform surface, and acceptable mechanical properties.
The tensile strength of soft pure copper sheets ranges from 200–250 MPa, and hardness is about 40–60 Vickers. With cold working (cold rolling), the strength can increase up to over 300 MPa in hardened condition. Copper sheets are easily formable and bendable, and in annealed condition, they are fully malleable.
Oxygen-free copper sheets (DLP/DHP) offer excellent solderability and brazing performance, and even Cu-ETP is solderable with proper measures. In terms of corrosion resistance, copper naturally withstands industrial atmospheres, marine environments, drinking water, and neutral alkaline or saline solutions. It may only corrode in contact with strong oxidizing acids, ammonia, or sulfur compounds. Therefore, copper sheet demonstrates high durability in diverse environmental conditions.
One key technical advantage of the offered products is the guaranteed conformity to standard chemical composition. All copper sheets are within the standard range and come with a chemical analysis certificate issued by the manufacturer for each batch. This ensures maximum electrical conductivity (minimum 100% IACS for Cu-ETP) and expected soldering behavior.
All domestic products mentioned are manufactured by reputable producers such as Bahonar, under ISO 9001 quality management systems, and undergo strict quality control regarding dimensional tolerances and surface defects. For instance, copper sheet surfaces are free from cracks, flakes, and discontinuities, and edges are cut clean and smooth.
Copper sheets are produced in a wide range of thicknesses and sizes. Thickness may vary from fractions of a millimeter (such as 0.1–0.2 mm foils for special applications) to several centimeters. In the Iranian market, thin copper sheets are typically supplied in coils (e.g., 0.1, 0.2, 0.3 mm), while thicker ones (0.5 mm to 15–16 mm) are offered as flat sheets in standard dimensions.
Typical standard size of domestic copper sheets is about 660 × 2000 mm (based on Bahonar’s rolling mill). However, custom sizes such as 1×2 m or 1.25×2.5 m can also be provided. Thick copper plates (above 50 mm) are also available upon request.
Advanced manufacturers such as KME Germany produce copper sheets by both cold rolling (up to ~3 mm thickness and 1600 mm width) and hot rolling (up to 240 mm thickness and 4 m width). Therefore, Taban Mes Iranian can also supply custom sizes and thicknesses from international sources.
In terms of weight, each square meter of 1 mm thick copper sheet weighs about 8.94 kg (based on density 8.94 g/cm³). Thus, weights for other thicknesses can be estimated accordingly. For example, a 5 mm sheet would weigh approximately 44.7 kg/m². Knowing the weight is important for estimating cost and transport logistics.
Packaging of copper sheets varies based on their form (sheet or coil) and thickness. Thin copper sheets (foils and coils) are delivered as rolls wound around cardboard cores or spools, with anti-scratch paper or plastic layers placed between them to protect the surface. Thicker sheets are laid flat on wooden pallets, wrapped with bubble wrap or oiled paper to prevent scratching and oxidation during transportation. The entire package is secured with metal straps. Each package typically includes a label with alloy type, dimensions, heat/batch number, and manufacturer details for traceability. For export purposes, special sea freight packaging is used, including pressed wooden boxes and extra moisture-resistant covers. All packaging complies with international transport standards to ensure the product’s quality and integrity during shipment. Given its high value, copper sheet is packaged and handled with great care.
Taban Mes Iranian offers copper sheets from trusted domestic and international manufacturers. Among domestic producers, Shahid Bahonar Copper Industries (Kerman) is renowned for its high-quality sheets with 99.99% copper purity. Bahonar sheets are available as rolls, standard sheets, or custom-cut pieces per customer request. The Khaavarmes sheets distributed through the company’s network are also produced locally with guaranteed quality. Additionally, Mesbar Kaveh, a leading domestic manufacturer of copper profiles, supplies a share of the market’s copper sheets and strips.
For imports, Taban Mes Iranian supplies copper sheets from major European brands such as KME Group (Germany/Italy), one of the largest global producers of copper and copper alloys; Aurubis (Germany – the largest copper producer in Europe); and Wieland Group (Germany – a leader in semi-finished copper products). These sheets can be imported in special grades and sizes, including wide formats and specialty alloys. All imported products are authentic and come with factory-issued quality certificates. Customers can therefore select the best option from both premium local and world-class international brands.
Introduction
A copper strip (also called a copper flat bar) is a relatively thick, rectangular section of copper typically produced in a few millimeters thickness and widths of several centimeters. It is available in straight bars or coils. In the Iranian market, “copper strip” often refers to flat copper busbars in smaller dimensions used for electrical and grounding applications. These strips are chemically identical to copper sheets (typically pure copper with 99.9% purity in TPC, DLP, or DHP grades), with the primary differences being in shape, dimensions, and production method. Copper strips can be made either by slitting thick sheets into narrower widths or by direct extrusion. Taban Mes Iranian supplies copper strips in standard and custom dimensions, both in annealed (soft) and cold-worked (hard) conditions. Annealed strips are flexible and easily bendable, while hard strips offer higher strength.
Applications of Copper Strips
Due to their rectangular geometry and excellent conductivity, copper strips play a crucial role in electrical connections and grounding systems. Common applications include:
• Grounding systems: Used as grounding tape in earth pits and building grounding grids, connected to rods or plates via clamps (e.g., 30×3 or 30×5 mm).
• Power distribution panels: Employed as small busbars (e.g., 20×3 or 20×5 mm) for connecting switches and terminals in compact spaces.
• Electrical connectors: Used in making shunts, jumpers, lugs, and flexible braided connectors for moving parts (e.g., generator to panel).
• Electronics and telecommunications: Used in high-current rectifier bridges and as shielding tapes in coaxial and telecom cables.
• Industrial uses: Applied in solar cells, battery connectors, conductive washers, and welding equipment due to formability and solderability.
Chemically, copper strips are the same as copper sheets, made from pure copper in TPC, DLP, or DHP grades. The alloy choice depends on the application: DLP/DHP is preferred for hydrogen-sensitive brazing/welding, while TPC is ideal for maximum conductivity. All copper strips offered have excellent conductivity (90%–100% IACS) and very low electrical resistance.
A rule of thumb: copper can carry ~1.7 A per mm² cross-sectional area (under standard thermal conditions). The cross-section must be selected based on current capacity to avoid voltage drop and overheating.
Mechanically, annealed copper strips are flexible and can be bent to small radii without cracking. Their tensile strength ranges from 200–220 MPa in annealed condition and up to 250–300 MPa when cold-worked. Extruded strips have finer grain structure and higher strength. Surfaces are typically shiny and oxide-free but may oxidize over time. Tin coating is used to prevent oxidation and improve bolt connection surfaces. Taban Mes Iranian offers tin- or even silver-plating upon request.
Copper strips are produced in a wide range of sizes. The typical thickness of flat copper strips available in the market is between approximately 3 mm to 10 mm. Thinner thicknesses (such as 1 or 2 mm) also exist, but they are usually classified as soft copper tapes or thin copper strips. The width of the strip can range from around 10 mm (1 cm) to 100 mm or more. Common widths in the Iranian market are 20, 30, 40, 50, and 60 mm, which are sufficient for most grounding and electrical panel applications. F…
Copper strip packaging is similar to that of busbars. Thin and narrow strips (flexible copper tapes) are usually packed in coils. These coils are wound around spools or suitable reels and secured with plastic straps to prevent uncoiling. The coils are often wrapped in stretch film or plastic to prevent direct contact with air and moisture. Thicker strips, supplied in 3 or 4-meter straight lengths, are bundled together—several pieces are stacked and tightly strapped with metal bands. Edge protectors or c…
Taban Mes Iranian also supplies copper strips from both domestic and international manufacturers. The majority of domestic copper strips are sourced from Shahid Bahonar Copper Industries in Kerman and Mesbar Kaveh. Bahonar has dedicated rolling and extrusion lines and produces strips with 99.98% copper purity in dimensions ranging from 3×20 mm to 10×120 mm. Mesbar Kaveh (located in Kaveh Industrial City) is a major producer of copper strips for grounding and flat busbar applications in Iran. Bahonar and…
Imported copper strips from the German brand KME (and Italy) are also available. KME manufactures strips with precise thicknesses and custom widths in standard alloys (ETP, DHP, etc.) and uses advanced packaging for safe transportation. Additionally, Wieland and Aurubis, leading international copper suppliers, include strips and copper tapes in their product ranges. For instance, Wieland offers copper strips in C11000 (ETP) grade with both rounded and flat edges. Taban Mes can import these upon customer …
Introduction to Copper Busbar
A copper busbar is a type of flat electrical conductor with a large cross-sectional area, designed for transmitting high electrical currents and distributing power in switchboards and power systems. Copper busbars typically have a rectangular cross-section and are made from high-purity copper with excellent conductivity to minimize voltage drop and energy loss. In industrial electrical panels, copper busbars serve as the backbone of current distribution, facilitating numerous branches and connections.
Because large currents flow through busbars, electrical conductivity and current-carrying capacity are critical. Therefore, they are usually made from TPC-grade copper (~101% IACS conductivity) or special oxygen-free copper to prevent oxidation. Copper busbars can be installed as straight lengths or machined parts (bent, drilled, coated). Taban Mes Iranian provides high-quality copper busbars in various dimensions and types (bare or coated), understanding the vital role of this component in the power industry.
Applications of Copper Busbar
Copper busbars are primarily used in power systems and high-current distribution applications. Common uses include:
• Low and Medium Voltage Switchboards: In factory, commercial, and substation panels, copper busbars are the main conductors distributing three-phase and neutral power to different sections. In low-voltage panels, horizontal and vertical busbars transmit current from the main inlet to circuit breakers and fuses.
• Diesel Generators and UPS Units: Connecting large generators to the network requires high-capacity copper busbars. In UPS systems, copper busbars connect rectifiers, batteries, and inverters for both DC and AC power distribution.
• Bus Duct Systems: In tall buildings or industrial sites, bus duct channels containing parallel copper busbars are used for high current transfer between panels. These busbars, insulated appropriately, carry current over long distances with minimal loss.
• Power Plants and High-Voltage Substations: In places like substation bus sections (bare copper/aluminum bars in the yard) and power plants, while aluminum is often used, copper is preferred for connections to equipment (transformers, switches), for very high currents, or in limited spaces.
• Automotive and Emerging Technologies: With the rise of electric vehicles and energy storage systems, flat copper busbars are increasingly used in battery packs, power inverters, and fast chargers. For instance, in EV battery packs, thin but wide copper busbars connect modules and carry hundreds of amps.
In summary, wherever safe and efficient high-current transfer with minimal voltage drop is required, copper busbars are the preferred solution. Their large contact surface allows multiple cable lugs or terminals to be connected, enabling easy distribution to multiple circuits. Replacing multiple cables with busbars simplifies wiring, enhances safety, and eases maintenance in panels.
Copper busbars are almost always made from pure copper with the highest possible electrical conductivity. The most common material for busbars is electrolytic tough pitch copper (Cu-ETP or UNS C11000), which contains at least 99.9% copper and small amounts of impurities, providing an electrical conductivity of approximately 100% to 101% IACS.
This type of copper has moderate hardness and strength, sufficient for mechanical needs of busbars, and is more cost-effective than special alloys. In cases where busbars need to be soldered or welded (to connect to other components in unprotected environments), oxygen-free copper such as Cu-HCP or Cu-DHP can be used to avoid hydrogen embrittlement. However, due to a 5–10% reduction in conductivity compared to ETP, the power industry generally prefers ETP copper and uses mechanical connections (e.g., bolts and nuts) instead of welding.
Copper busbars must carry the rated system current continuously without exceeding a specified temperature (usually 85°C for class F insulation). Therefore, the cross-section of the busbar is designed according to the current. For example, a copper busbar with a 1000 mm² cross-section (approximately 10mm × 100mm) can continuously carry ~1700 amps (assuming 1.7 A/mm²). For higher currents, multiple busbars can be used in parallel, or the dimensions can be increased.
The electrical resistance of copper busbars is very low. For instance, the resistance of one meter of a 50×5 mm busbar (250 mm² cross-section) is about 0.00007 ohms, resulting in a minimal voltage drop of around 0.007 volts per ampere-meter. Copper also has a relatively low thermal coefficient of resistance, maintaining good conductivity even at elevated temperatures. Copper has a high melting point (~1083°C), making busbars resistant to deformation under short-circuit currents that generate sudden heat.
To improve connection durability, copper busbars are often tin-plated. Tin coating reduces surface oxidation and extends the lifespan of bolted connections (tin oxide remains conductive, unlike copper oxide). Tin is softer than copper, allowing better electrical contact when bolts are tightened. Some high-end busbars are silver-plated, which provides superior conductivity and corrosion resistance, albeit at a higher cost.
Taban Mes Iranian offers both bare (uncoated) and tin-plated copper busbars. Bare busbars have a bright copper color and are suitable for indoor, dry installations. For panels exposed to moisture or corrosive environments, tin-plated types are recommended.
All supplied busbars conform to international standards such as DIN 13601 / EN 13601 (European standard for copper and copper alloys for electrical applications), ASTM B187 (American standard for copper bars and busbars), ASTM B133M (copper flat rods and bars), and JIS H3250 (Japanese standard). Compliance with these standards ensures appropriate chemical composition, mechanical properties, dimensional tolerances, and defect-free surfaces, as expected in the electrical industry.
Domestic manufacturers like Shahid Bahonar factory inspect their busbars using eddy current testing to ensure absence of internal cracks or discontinuities. Straightness and flatness are also checked to facilitate easy panel mounting.
Copper busbars are available in a wide range of standard sizes. Typical dimensions include thicknesses from about 2 mm to 20 mm and widths from 20 mm to 125 mm. Shahid Bahonar, the largest copper busbar manufacturer in Iran, offers dimensions from 2×20 mm to 20×125 mm in lengths ranging from 2 to 10 meters.
Common sizes include:
• Thicknesses: 3, 5, 6, 10, 12 mm
• Widths: 20, 30, 40, 50, 60, 80, 100, 125 mm
For example, 5×50 mm and 10×80 mm are common in low-voltage panels, while 10×100 mm or 20×100 mm are used in main panels and interconnections. Very wide (up to 160 or 200 mm) or very thick (25 or 30 mm) busbars can be custom-made for specific industries.
To increase current capacity, multiple thinner busbars are often used in parallel instead of a single thick one to improve cooling and connection flexibility.
In terms of edge shape, copper busbars are classified as sharp-edged (square) or round-edged. Sharp-edged types have 90° corners, while round-edged types are slightly filleted. Round edges cost more but reduce corona discharge in high voltages and are easier to insulate (e.g., with shrink tubing). For low-voltage networks, sharp edges are usually sufficient.
Standard busbar lengths are typically 4 or 5 meters (for transport convenience), but 6 meters or more can be made upon request. During panel installation, busbars are usually cut and drilled to custom lengths, so the initial length affects installation efficiency but not operation performance.
Due to the relatively high weight and the importance of keeping copper busbars straight, their packaging is carried out with care. After production and inspection, the busbars are typically bundled in groups of 5 to 10. They are stacked and secured with metal straps at several points. At the strap locations, plastic or cardboard edge protectors are used to prevent damage to the edges. The entire bundle is then wrapped with plastic film to protect it from moisture and dust. Each bundle contains a tag with product details (dimensions, alloy, number of bars, gross and net weight, manufacturer name, and batch number). This allows customers to verify the product matches their order and enables traceability. Very long busbars (e.g., 6 or 10 meters) may be loaded as cradle-packed bundles to facilitate transportation—wooden cradles are placed on the trailer bed or container floor, and the busbars are secured on them to prevent bending.
For export purposes, in addition to the above, packaging may include large wooden crates or special pallets to prevent damage during repeated handling in ports and customs. If the busbar is tin-plated, nylon or waxed paper must be placed between the packed bars to prevent discoloration or stains during long-term storage. Transportation is mainly carried out by flatbed trucks or containers, and unloading requires lifting equipment (such as forklifts or overhead cranes), as each bundle may weigh several hundred kilograms. Overall, the packaging is designed to ensure that the copper bars arrive at the project site straight, intact, and ready for installation.
Taban Mes Iranian supplies both domestically manufactured and reputable imported copper busbars. In the domestic market, Shahid Bahonar Copper Company is the main supplier, with its own dedicated busbar plant. Bahonar’s busbars are produced using extrusion and rolling technology, providing high quality, and a large portion of their production is exported to European and Asian markets. Another producer, Mesbar Kaveh, manufactures commonly used busbar profiles (mostly up to 10 cm wide), and its products are used in electrical panels for many industrial projects. Taban Mes Iranian offers the products of these two manufacturers at competitive prices with quality assurance. All domestic busbars come with standard chemical analysis (Table 1) and a factory quality certificate (including electrical and mechanical test results).
For international brands, Taban Mes Iranian can supply European-made copper busbars. For example, Wieland Germany (and its subsidiary Farmer’s Copper) is well known globally and produces C11000 grade busbars in both rounded and square edges. These busbars are available in standard 12-foot (3.66-meter) lengths and various profiles. KME also produces premium-grade busbars suitable for specialized projects.
Although Aurubis mainly focuses on copper cathodes and raw materials, it supplies busbars and fabricated copper parts through its partners. If customers need imported busbars (e.g., for specific profiles or special coatings), the company guarantees product authenticity and can fulfill the order. All imported busbars are delivered with the manufacturer’s certificate, including results of electrical conductivity, chemical composition, and dimensional tests, ensuring full confidence in product quality.
