Product Introduction
Overview
The Affordable Factory Outlet Galvanized Steel Coils (Z20-Z275g) are high-quality metallurgical products designed for cost-sensitive buyers seeking reliable corrosion resistance and formability. Directly sourced from the manufacturer, these coils feature hot-dipped zinc coatings ranging from Z20 (20g/m²) for indoor use to Z275 (275g/m²) for severe outdoor environments, ensuring optimal protection across diverse applications.
Constructed with low-carbon steel substrates (SPCC, SGCC grades), the coils undergo rigorous galvanization to create a uniform zinc layer that combines sacrificial protection with mechanical durability. Available in thicknesses from 0.15mm to 3.0mm and widths up to 1250mm, they balance affordability with performance, making them ideal for large-scale fabrication in construction, appliances, and general metalworking.
Features
Wide Coating Range for Diverse Needs:
Z20-Z100: Economical options for indoor storage racks, office furniture, and non-exposed components (service life: 5-10 years in dry conditions).
Z180-Z275: Heavy-duty coatings for coastal roofing, industrial cladding, and transportation equipment (salt spray resistance: 1,000-2,000 hours).
Factory-Direct Value Proposition:
Eliminates middleman markups, offering prices 15-20% lower than market rates for bulk orders (50+ tons).
Custom slitting and cut-to-length services at no extra cost, reducing material waste in production lines.
Formability & Process Compatibility:
Smooth surface finish (spangle/spangle-free) enables easy painting, powder coating, and lamination for aesthetic or protective purposes.
Excellent ductility (elongation ≥26% for Z100) supports deep drawing, roll-forming, and stamping for complex shapes like appliance panels.
Quality Assurance:
Meets international standards (ASTM A653, EN 10143), with mill certificates verifying coating weight, tensile strength, and corrosion resistance.
Stringent quality control: <0.5% surface defect rate, ensured through automated optical inspection during production.
Application
Construction Industry: Fabricates lightweight roof trusses, wall cladding, and C/Z purlins for prefab homes and industrial sheds, with Z180g coating resisting moderate humidity.
Home Appliances: Forms inner panels for refrigerators, washing machines, and air conditioners, providing a stable base for enamel coatings at competitive costs.
Automotive Components: Produces truck body panels, trailer frames, and underbody shields, with Z275g coating protecting against road salt and moisture in harsh climates.
General Fabrication: Ideal for metal furniture, signage, and HVAC ductwork, offering a balance of affordability and rust resistance for both indoor and outdoor use.
FAQ
Q: How do I choose the right coating weight for my project?
A: Select Z20-Z100 for dry indoor environments, Z180 for urban outdoor use, and Z275 for coastal/industrial zones. Our team provides free consulting to match your environmental needs.
Q: What is the minimum order quantity for factory outlet pricing?
A: Standard coils (5-10 tons) are available at factory prices; smaller orders (1-5 tons) are subject to a nominal processing fee.
Q: Can I get a sample to test formability?
A: Yes, free 300x300mm samples with your chosen coating weight and surface finish are available upon request.
Q: How does galvanized steel compare to galvalume in cost?
A: Galvanized (zinc-only) is 20-30% more affordable than galvalume (aluminum-zinc alloy), making it ideal for budget projects not requiring extreme corrosion resistance.
