توضیحات محصول
Galvalume Steel Coil for Roofing and Industrial Use High Corrosion Resistant Alu Zinc Coated Steel Coil

High quality Galvalume Steel Coil also known as Alu Zinc coated steel coil with superior corrosion resistance 2 to 6 times longer lifespan than GI widely used in roofing appliances and industrial panels competitive price factory direct supply.

Galvalume Steel Coil also referred to as Alu Zinc coated steel coil is an advanced coated steel material produced by a continuous hot dip process. The steel substrate is coated with an aluminum zinc alloy layer typically containing 55 percent aluminum small silicon content and zinc balance. This structure creates a highly durable barrier combining aluminum protection and zinc sacrificial performance.

Compared with traditional galvanized steel Galvalume Steel Coil offers significantly enhanced durability making it an ideal material for long term outdoor and industrial applications. The surface presents a uniform silver gray appearance with a distinctive spangle pattern suitable for both functional and decorative uses.

Key Advantages

Superior Corrosion Resistance for Harsh Environments

Galvalume Steel Coil delivers 2 to 6 times longer service life than standard galvanized steel. It performs exceptionally well in marine industrial and high humidity environments making it a reliable choice for roofing and exterior structures.

Dual Protection Mechanism

The aluminum component forms a dense protective barrier while zinc provides electrochemical protection at cut edges and scratches ensuring long term structural integrity.

Excellent Heat Reflectivity and Energy Efficiency

Alu Zinc coated steel coil reflects heat effectively reducing building temperature and improving energy efficiency especially for roofing systems in hot climates.

Outstanding Surface Quality

Smooth bright silver finish with options including regular spangle minimized spangle and skin passed surface suitable for painting or direct use.

Frequently Asked Questions
What is Aluminum-Zinc Coated Steel?
It is a steel sheet coated with an alloy consisting of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This unique composition combines the corrosion resistance of aluminum with the sacrificial protection of zinc.
What is the difference between GI (Galvanized) and GL (Galvalume)?
GI (Galvanized): Coated with pure zinc. Offers excellent sacrificial protection but has shorter lifespan in corrosive environments.
GL (Galvalume): Coated with aluminum-zinc alloy. Provides 3 to 6 times better corrosion resistance than GI and superior heat reflectivity.
What surface finishes are available?
We offer three main surface types:
  • Regular Spangle: Standard crystalline pattern
  • Minimized Spangle: Fine, uniform surface appearance
  • Zero Spangle: No visible pattern, ideal for painting applications
Can it be painted?
Yes. We supply Pre-Painted (PPGI/PPGL) coils with various coatings including polyester, silicon modified polyester (SMP), or PVDF (fluorocarbon). We also supply bare (unpainted) coils suitable for post-painting processes.
What thicknesses and widths are available?
Thickness: 0.12mm to 2.0mm (custom sizes available)
Width: 600mm to 1,250mm (custom sizes available upon request)
What are the common applications?
  • Construction: Roofing sheets, wall cladding, gutters, sandwich panels
  • Home Appliances: Air conditioner covers, refrigerator back panels, ovens
  • Industrial: Automotive parts, agricultural equipment
How is the coil packed for export?
For seaworthy transportation protection, we use anti-rust oil film, waterproof kraft paper, galvanized iron sheet wrapping, and steel pallets with edge protectors to ensure product integrity during shipping.
