Product Introduction
Galvanized Sheet Coil
1. Galvanized Sheet Coil - Product Overview & Core Definition
Product Name: Galvanized Sheet Coil (Hot-Dip Galvanized Steel Coil, GI Coil)
Core Process: Carbon steel coil with continuous hot-dip galvanized zinc coating
Core Function: Provide long-term corrosion resistance and structural strength
Application Scope: Global export for construction, manufacturing, and general engineering industries
2. Core Technical Features & Specifications
Substrate Material: Cold-rolled or hot-rolled carbon steel
Surface Coating: Zinc coating (Z20–Z275 g/m²), available in regular/minimum/zero spangle finishes
Size Range: Thickness 0.12–6.0mm, width 50–1500mm, coil weight 3–10MT
Mechanical Properties: High tensile strength, good ductility, excellent formability
Surface Quality: Smooth, uniform coating; no bare spots, scratches, or defects
3. Competitive Advantages
Corrosion Resistance: Zinc coating provides barrier protection and cathodic protection against rust
Cost Efficiency: Lower cost than stainless steel with comparable anti-corrosion performance
Processability: Easy to cut, bend, stamp, weld, and form for downstream manufacturing
Long Service Life: Outdoor durability of 10–25 years depending on environment and coating weight
Versatility: Suitable for painting, powder coating, and other secondary surface treatments
4. Typical Applications
Construction: Roofing, wall cladding, corrugated sheets, structural supports
Light Industry: Metal furniture, cabinets, shelves, and household appliances
Automotive & Transportation: Chassis parts, brackets, and interior components
Agriculture & Infrastructure: Greenhouse frames, silos, guardrails, and drainage systems
Downstream Processing: Raw material for making PPGI, color-coated sheets, and profiled panels
5. Export Support & Services
Customization: Slitting, cutting, and coil-to-sheet processing available
Quality Assurance: Mill Test Certificates (MTC) and third-party inspection reports (SGS/BV)
Packaging: Standard seaworthy export packaging (anti-rust paper + VCI film + steel strapping + pallets)
Trade Terms: FOB / CFR / CIF / EXW; flexible payment methods (T/T, L/C at sight)
Logistics & MOQ: MOQ starting from 1MT; bulk vessel and container shipment options
FAQ:
Q1: How long is your delivery time?
