The offering is copper‑clad steel (CCS) supplied by CS‑Tech in South Korea, where a low‑carbon steel substrate is coated with copper ranging from 5 % to 40 % by weight. The material is available as sheet or coil, with typical thicknesses from 0.2 mm to 2.0 mm and standard widths of up to 1500 mm. CS‑Tech describes the CCS as a bi‑metallic composite that balances the conductivity of copper with the mechanical strength of steel. The product meets international standards for electrical conductors and is manufactured under controlled coating processes.
Standard CCS sheets exhibit a copper resistivity of 1.7 µΩ·cm and a tensile strength between 300 MPa and 600 MPa, depending on the copper content. Dimensional tolerances commonly fall within ±0.05 mm for thickness and ±1 mm for width, which aligns with the values supplied by CS‑Tech. Typical surface finish is a bright copper layer that may develop an oxidation colour, a characteristic noted in the supplier’s description. The material is usually packed in moisture‑proof film and bundled on pallets for export, a practice that protects the copper coating during transit.
CCS is employed in electrical conductors, printed circuit board panels, earthing strips and telecommunications infrastructure where cost‑effective conductivity is required. Buyers such as cable manufacturers, PCB fabricators and utility companies often request FOB or CIF terms and settle payments via L/C or T/T. CS‑Tech indicates that order sizes are adjustable to meet both prototype and mass‑production needs, but exact MOQ should be verified directly. Prospective importers are advised to confirm the copper percentage, thickness tolerance and delivery schedule before finalising the contract.

CS‑Tech is based in Busan, South Korea, with its registered address at 87‑7 Noksansandan 261‑ro, postal code 46753. The supplier holds a harbor trust tier, reflecting successful completion of the platform’s basic verification process. Its response metrics show a 0 % response rate and no average response time, indicating that initial contact may require multiple attempts. CS‑Tech positions itself as a producer of copper‑clad steel composites for industrial use.
The product description notes adjustable copper content between 5 % and 40 % and lists typical thicknesses, but the supplier does not disclose exact batch certifications, production lead time or MOQ in the public data. No explicit payment terms or Incoterms are included, so buyers should ask for a formal quotation that details these conditions. The company’s profile does not mention any third‑party testing laboratories, so verification of coating thickness and adhesion should be requested.
Copper Clad Steel (CCS) is a bi-metallic composite material combining the conductivity of copper with the strength of steel, offering an economical alternative to solid copper for electrical and industrial applications. Available in adjustable copper content (typically 5-40%) and various thicknesses, CCS provides excellent solderability, corrosion resistance, and formability while reducing raw material costs by up to 50%. Widely used in electrical conductors, printed circuit boards, earthing systems, and telecommunications infrastructure, this product is traded globally in coil and sheet formats meeting international standards.

Potential buyers must obtain a coating thickness report that specifies the copper layer on the steel substrate, as this determines conductivity and corrosion resistance. Request documentation that confirms the copper content falls within the 5 % - 40 % range stated by CS‑Tech. Verification of the steel grade, typically low‑carbon, should also be included in the technical data sheet. Any discrepancy between the supplied data and the received product must be recorded before acceptance.
Discuss the Incoterm early in the negotiation; CS‑Tech can ship on FOB Busan or CIF a nominated destination port. Clarify the expected lead time, which depends on the coil or sheet thickness and current production schedules. Payment is usually arranged via irrevocable L/C or T/T, but the exact schedule should be documented in the sales contract. Ensure that the commercial invoice lists the exact thickness, width and copper percentage for customs purposes.
On receipt, conduct a resistivity test to verify the typical 1.7 µΩ·cm value for the supplied copper‑clad steel. Perform a tensile test to confirm the material meets the 300 MPa - 600 MPa strength range appropriate for the declared copper content. Inspect the packaging for moisture‑proof film integrity and any signs of oxidation on the copper surface. Request the mill test report and any third‑party certification to complete the quality assurance process.
