Surface Passivation & Treatment Options

To ensure optimal performance during your downstream manufacturing, painting, or storage processes, we provide highly customizable surface treatments:

  • Passivation: Chromate passivated or non-chromate (RoHS compliant) passivated options available to prevent white rust during transit.

  • Oiling: Light oil, no oil, or completely dry surfaces, tailored to your specific stamping, forming, or coating requirements.

Heavy-Duty Commercial Applications

Our galvanised coils and sheets form the structural backbone for numerous demanding sectors:

  • Construction Infrastructure: Corrugated roofing, steel framing profiles, and HVAC ventilation ductwork.

  • Automotive & Transport: Internal structural components and underbody panelling.

  • Industrial Fabrication: Electrical enclosures, heavy appliance housings, and agricultural storage silos.

Request a Bulk Manufacturing Quote

As a primary China manufacturing source, we facilitate scalable metal supply chains for global steel service centres, construction contractors, and OEM fabricators. Please provide your exact material grade (e.g., DX51D), dimensions (Thickness × Width), Zinc coating weight (g/m²), preferred surface treatment, and total metric tonnage to receive an official factory-direct price and a production lead time.
