Procurement FAQ
Frequently Asked Questions by Overseas Buyers
Our vertical coating line operates in strict accordance with AAMA 2604 and AAMA 2605 standards for high-performance architectural coatings, as well as Qualicoat specifications. Mill test reports and salt-spray test certificates are supplied for all export shipments.
Standard single-coat applications maintain a uniform film build of 60 to 80 microns. Dual-layer PVDF/fluoropolymer coatings for severe coastal or high-UV environments can achieve 100+ microns, backed by performance warranties of up to 15–25 years depending on resin grade.
We supply over 100 standard RAL shades in matt, semi-gloss, and high-gloss textures, as well as metallic, sand-blast effect, and timber wood-grain sublimation. Custom spectrophotometer color matching is available upon sample submission.
Every coated profile is interleaved with protective non-abrasive paper or PE film, bundle-wrapped in polyethylene shrink wrap, and packed into reinforced wooden crates or steel-framed pallets designed for rigid container loading.
