Import Coated Aluminum Coil — Buy in Bulk from Supplier in China

Coated aluminum coil from GH Aluminum is a continuous strip of aluminum alloy, typically 0.2mm to 3.0mm in thickness and up to 1,600mm in width, with a polymer-based protective and decorative finish applied through roll coating. The base material is generally 3xxx or 5xxx series alloy, selected for its balance of formability and corrosion resistance. The coating system includes a primer, color layer, and topcoat, applied in a continuous inline process to ensure uniform adhesion and thickness.

The coating type is typically polyester (PE) or polyvinylidene fluoride (PVDF), with PVDF offering superior UV resistance and color retention over 20+ years in outdoor exposure. Standard coating thickness ranges from 18 to 25 microns for PE and 25 to 35 microns for PVDF. Surface finishes include matte, gloss, metallic, and embossed textures, with color options following RAL or Pantone standards. The aluminum substrate meets ASTM B209 or EN 573-3 standards for chemical composition and mechanical properties.

This product is widely used in architectural cladding, roofing, ceiling systems, and transportation paneling. Buyers include construction contractors, facade engineers, and appliance manufacturers sourcing for durable, low-maintenance surfaces. Trade terms are typically FOB Guangzhou or CIF destination port, with standard packaging in wooden crates with moisture barriers. Minimum order quantities are flexible but often start at 1 metric ton for custom colors. Lead times vary by color and volume, and certification documentation must be requested prior to order.

GH Aluminum operates from Guo Village, Fangxin Rd., near Guangzhou, China. The listing indicates an imported supplier tier with harbor-level trust verification, suggesting the company is engaged in export logistics but provides no details on production capacity, years in operation, or workforce size. No certifications, client list, or factory audits are referenced in the source data. The supplier responds to inquiries at a rate of 0.00% with no average response time recorded, indicating limited or no direct communication capability.

The product listing does not confirm whether GH Aluminum manufactures the coil or acts as a trader. There is no mention of in-house coating lines, alloy sourcing, or quality control protocols. Buyers should treat this as a sourcing intermediary unless independent verification confirms production capability. All technical claims must be validated through direct request for material test reports and coating adhesion test results.
