Product Overview
We supply Z275 galvanized steel coils and galvalume steel coils in 0.35mm thickness, offering two of the most widely used corrosion-resistant coated steel products for construction, roofing, appliance manufacturing, and general industrial applic
ations. Both products are available with competitive per-kilogram pricing, flexible order quantities, and reliable global delivery.
Z275 Galvanized Steel Coil features a pure zinc coating (275g/m² total both sides) applied through hot-dip galvanizing, providing sacrificial corrosion protection and excellent formability.
Galvalume Steel Coil features a 55% aluminum-zinc alloy coating, delivering superior heat reflectivity, enhanced corrosion resistance in marine and industrial atmospheres, and longer service life compared to conventional galvanized products.
At 0.35mm thickness, these coils are ideal for lightweight roofing sheets, wall cladding, ductwork, and formed structural components where material efficiency and cost control are critical.

FAQ
Q: Is 0.35mm thickness strong enough for roofing applications?
A: Yes. 0.35mm is a standard thickness for residential and light commercial roofing in many markets. For industrial buildings, high-wind zones, or longer span applications, 0.40mm–0.50mm may be preferred. We can advise based on local building codes and load calculations.
Q: Can you supply coils slit to custom width?
A: Yes. We offer precision slitting from master coils to widths as narrow as 30mm. Edging and burr removal are included. Custom width coils reduce scrap and processing time for roll forming and stamping operations.
Q: Do you offer pre-painted (color-coated) galvanized or galvalume coils?
A: Yes. We supply PPGI (pre-painted galvanized) and PPGL (pre-painted galvalume) coils in a wide range of colors and finishes (PE, SMP, HDP, PVDF). Paint thickness typically ranges from 15–25 microns topcoat and 5–10 microns primer.
Q: What is your minimum order quantity (MOQ) and typical lead time?
A: Standard MOQ is one 20-foot container (approximately 25–28 metric tons). For trial orders, mixed-grade containers, or non-standard specifications, please contact us for flexible arrangements. Lead time is typically 15–25 days for stocked specifications; 30–45 days for custom orders.
