Import Dx53d Galvanized Roof Sheet — Buy in Bulk from Supplier in Viet Nam

DX53D Galvanized Roof Sheet is a cold-rolled steel product with a zinc coating designed for roofing applications requiring enhanced durability. The material is produced to meet international standards including ASTM, EN, and GB, with thickness options from 0.12 mm to 6 mm. Zinc coating weights typically range from 60 g/m² to 600 g/m², selected based on environmental exposure. Surface treatments include chromated, oiled, and skin-passed finishes to improve handling and corrosion resistance.

DX53D is a higher-strength grade than DX52D, with improved yield strength and formability suitable for long-span roofing systems. The steel substrate contains controlled levels of titanium and niobium to stabilize grain structure, enhancing weldability and resistance to deformation under load. Common surface finishes are regular spangle and minimum spangle, chosen for aesthetic preference in commercial and residential buildings. Packaging is typically in waterproof-wrapped coils with iron banding for ocean transport.

This product is used in industrial warehouses, agricultural sheds, commercial buildings, and residential rooftops where long-term weather resistance is critical. Buyers include contractors, building material distributors, and project developers sourcing for regions with high rainfall or coastal salinity. Trade terms are negotiable, but buyers must confirm packaging configuration, minimum order quantity, and incoterms directly with the supplier. Custom lengths and slitting services may be available upon request.

Shandong Jintuo Metal Materials Co., Ltd is based in Liaocheng City, a major steel trading center in China. The company operates as a trading entity sourcing galvanized steel products from certified mills, with no indication of in-house production. Its listing shows an imported supplier status with harbor trust tier, but no verified response rate or communication history is recorded.

The supplier does not claim certifications, production capacity, or testing facilities. While the listing references DX53D as a high-performance product, no evidence is provided of mill origin, chemical analysis, or coating validation. Buyers must request independent test reports and confirm the source of the steel substrate before committing to bulk orders.
