Product Overview
Our GI (Galvanized Iron) Coil and Sheet Galvanized Steel are engineered to deliver superior corrosion resistance, durability, and versatility for a wide range of industrial and commercial applications. Manufactured in compliance with international standards such as ASTM, JIS, DIN, EN, and GB , these products feature a hot-dip galvanized coating that forms a robust zinc-iron alloy layer, protecting the steel substrate from rust and environmental degradation. The zinc coating thickness ranges from Z30 to Z600 g/m² , ensuring long-term performance in harsh conditions. Available in materials like DX51D, SGCC, G350, and G550 , our products are suitable for structural, automotive, and architectural uses.
Key highlights include:
Global Standards Compliance: Meet ASTM A653, JIS G3302, and EN 10346 , ensuring reliability for international markets.
Customizable Specifications: Thickness, width, and surface finishes (bright, mill, polished) tailored to project requirements .
Sustainability: Recyclable material with a lifespan of up to 80 years (Z600 coating) , aligning with green building practices.
Product Features
Material
Our galvanized steel is produced using high-grade alloys like SGCC (for general forming), SGCH (high-strength), and G550 (extra-high strength) . These materials offer excellent formability and weldability, making them ideal for complex fabrications. The zinc coating acts as a sacrificial layer, corroding preferentially to protect the steel beneath, even when scratched or damaged .
Wide Range of Coatings
With zinc coating weights from Z30 to Z600 g/m² , our products cater to varying corrosion resistance needs. For example:
Z275 g/m²: Suitable for moderate environments (e.g., roofing, HVAC ducts) .
Z600 g/m²: Provides up to 80 years of protection in highly corrosive settings like coastal areas or industrial zones .
The coating's tight adhesion ensures no flaking during bending or welding .
Surface Finishes and Treatments
Choose from bright, mill, polished, or oiled surfaces . Optional post-coating treatments like chromate or VCI (Volatile Corrosion Inhibitor) paper enhance anti-corrosion properties and prevent white rust during storage. Zero-spangle (extra-smooth) finishes are available for aesthetic applications .
Precision Engineering
Tolerances: Thickness and width variations are tightly controlled to ensure consistency in fabrication processes .
Processing Services: In-house capabilities include bending, decoiling, and punching , enabling seamless integration into customer workflows.
Quality Assurance
All products come with Mill Test Certificates, ISO 9001, CE, and SGS certifications , guaranteeing adherence to rigorous quality benchmarks.
Applications
Construction Industry
Roofing & Cladding: Lightweight yet durable SGCC sheets with Z275 coating are widely used for roofing panels and building facades, offering resistance to UV rays and moisture.
Structural Components: G550 high-strength coils support load-bearing structures like steel frames and trusses .
Infrastructure: Bridges, railways, and water tanks benefit from Z600-coated sheets’ long-lasting corrosion resistance.
Automotive Sector
Body Panels: SGCC and DX51D materials provide corrosion protection for car bodies and chassis .
Exhaust Systems: Galvanized steel resists heat and chemical corrosion in exhaust components .
Appliance Manufacturing
Household Goods: SGCC sheets with smooth finishes are used in refrigerators, washing machines, and microwave casings .
Industrial Equipment: G350 coils protect industrial freezers and electrical cabinets from moisture and abrasion .
HVAC and Plumbing
Ductwork: Galvanized sheets with anti-friction coatings reduce airflow resistance in ventilation systems .
Pipes & Fittings: Z275-coated pipes withstand water corrosion in plumbing networks .
