JIS G3312 CGCC Prepainted Colour Steel Coil ASTM A653 Certified 914-1250mm Width Wall Cladding

Projects that cross borders usually cross standards as well, so this prepainted colour steel coil is produced and documented against JIS G3312 CGCC with equivalent compliance to ASTM A653 and EN 10169 where the buyer requires it. The coil is a hot dip galvanized base with a chromate conversion coating and a two coat paint system, supplied with mill test certificates stating grade, coating mass, mechanical properties and paint build in the format that third party inspection bodies accept. Widths from 914 mm to 1250 mm and thickness from 0.15 mm to 1.20 mm cover the common roofing, cladding and panel requirements, and certificates can be issued per heat or per shipment depending on the contract.

• Dual standard compliance: Produced to JIS G3312 CGCC and documented against ASTM A653 and EN 10169 equivalents, so the same coil can satisfy a Japanese specification and a United States specification project.
• Inspection ready documentation: Mill test certificates, coating mass reports, dimensional sheets and paint test results are issued in English with heat numbers, allowing third party inspectors to verify the shipment without re testing.
• Chromate conversion layer: A chromate passivation layer between the zinc and the primer improves paint adhesion and adds a secondary barrier against early edge corrosion.
• Consistent mechanical values: Yield strength, tensile strength and elongation are tested per heat, giving structural panel designers reliable input values instead of conservative assumptions.
• Grade flexibility: CGCC, DX51D plus Z, SGCC and S250GD plus Z are all available, so a distributor can serve several customer specifications from one supplier relationship.
• Export experience: Documentation has been prepared for customs, inspection agencies and project consultants in Southeast Asia, the Middle East, Africa and South America, reducing the risk of a shipment being rejected on paperwork.

This coil is chosen where documentation and traceability carry the same weight as the material itself. Applications include roofing and wall panels on contract projects, steel doors and frames, electrical cabinets, air conditioning casings, shelving and general sheet metal work. Distributors supplying construction contractors appreciate that one coil can be offered against a JIS based specification and an ASTM based specification, reducing the number of stock items they must carry. Government and infrastructure tenders that require third party inspection are supported with pre arranged SGS or BV visits and certificates issued against the purchase order number.

Coils are wrapped in waterproof paper and plastic film, edge protected with fibreboard rings and strapped to wooden skids suitable for container and break bulk shipment. Labels show standard, grade, heat number, size, coating mass and net weight. The document pack includes the mill test certificate, coating mass report, paint system report and packing list, all in English and cross referenced to the purchase order. Where third party inspection is required, we schedule the inspection before loading and release the certificate with the shipping documents so clearance is not delayed at destination.
