Import Color Coated Steel Sheet — Buy in Bulk from Supplier in China

Dalian Haiman Construction Group supplies corrugated color coated steel sheets with post-corrugation widths of 800mm, 840mm, 870mm, and 900mm, produced on galvanized or galvalume substrates with polymer coatings. The corrugation pitch is typically 76mm, and the depth measures 18mm, consistent with standard industrial profiles for roofing and cladding applications. These sheets are delivered in seaworthy packaging to prevent moisture damage during transit.

The base material is hot-dipped galvanized or Galfan-coated steel, providing corrosion resistance before the polyester-based topcoat is applied. While the supplier does not specify coating thickness or zinc weight, typical industry standards for such products include zinc coatings of 120-275g/m² and topcoats of 15-25 microns. The coating system is designed for outdoor exposure but is not certified for marine-grade environments without additional testing.

These sheets are commonly purchased by construction contractors in Southeast Asia and the Middle East for low-cost roofing and wall panels in industrial sheds, agricultural buildings, and temporary structures. Buyers typically order in full container loads, with lead times dependent on production scheduling. Packaging is standardized in bundles secured with steel straps and plastic film, but incoterms and payment terms must be confirmed directly with the supplier.

Dalian Haiman Construction Group is a trading entity based in Dalian, Liaoning Province, with a registered address at No1-4, Huaihe West Road E&t Development. The supplier is classified as an imported-tier entity with harbor-level trust verification, indicating documented export activity but no public certification or factory audit reports. The listing does not state production capacity, years in operation, or direct manufacturing control.

The supplier does not provide details on workforce, revenue, or client list. Response metrics show zero response rate and no average response time, suggesting limited buyer communication infrastructure. Buyers should treat this as a trading company sourcing product from third-party mills, not a verified manufacturer. Verification of material origin and coating compliance must be requested through independent inspection.
