Large-Scale Storage & Ready-to-Ship Inventory

Our modern indoor warehouse holds over 50,000 tons of PPGL coils, prepainted galvalume steel sheets, and corrugated roof tile raw materials. We maintain stock in standard RAL colors (such as RAL 9002, RAL 5012, RAL 3005) to ensure rapid order fulfillment for international distributors and construction contractors.

Automated Color Coating & Galvalume Production Lines

Equipped with 2 double-coat double-bake color coating lines and continuous galvalume dipping lines, our factory achieves uniform paint adhesion, vibrant color consistency, and extreme weatherability against UV radiation and coastal salt fog corrosion.

Strict Quality Assurance & In-House Testing Laboratory

Quality is strictly guaranteed before shipment. Every coil undergoes comprehensive physical and chemical testing to ensure zero peeling, zero cracking, and long-term corrosion protection.

Paint Film Thickness: Electromagnetic gauges verify micron-level paint distribution.
T-Bend Test: 0T–2T bend tests ensure paint coating flexibility without cracking during profiling.
Adhesion Test: Cross-hatch tape adhesion and impact testing.
Corrosion Resistance: Accelerated salt spray testing simulating harsh outdoor environments.

Seaworthy Export Protective Packaging

PPGL Coils are packed with waterproof paper, inner metal sleeves, plastic film wraps, galvanic steel outer ring protectors, and heavy-duty steel bands strapped onto strong wooden pallets to guarantee moisture-free ocean transit.

Container Loading & Ocean Logistics Supervision

Coils are anchored using vertical or horizontal loading arrangements (Eye-to-Sky / Eye-to-Side) with wooden chocks and heavy-duty wire ropes inside 20ft containers, ensuring total stability on rough seas.
