What is Aluzinc Sheet?
Aluzinc steel sheet, also known as galvalume steel, is an alloy-coated steel product made from a hot-dip-plated, cold-rolled steel substrate that is coated with an aluminum-zinc alloy consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon.
- Aluminum: provides heat resistance and forms a protective barrier against oxidation.
- Zinc: provides sacrificial protection against rust.
- Silicon: enhances adhesion and uniformity of the coating.
Benefits of Aluzinc Sheet
- Excellent corrosion resistance: The aluminum in zinc-aluminum alloy sheets is resistant to salt spray, humidity, and chemicals, and performs 2-4 times better than galvanized steel in coastal and industrial areas.
- Excellent heat resistance: The zinc-aluminum alloy coating can withstand temperatures up to 600°F (315°C).
- Lightweight and durable: Aluzinc Sheet is 20-30% lighter than galvanized steel, reducing structural loads while maintaining high tensile strength.
- Mechanical Properties: Aluzinc steel has high fracture resistance and can withstand mechanical stress.
- Aesthetic versatility: The surface layer has a silvery-white metallic color and is compatible with organic coatings (e.g. PPGI, PPGL) for customized colors and textures.
- Environmentally friendly and recyclable: GL steel is 100% recyclable, supporting sustainable building practices.
- Cost-effective service life: Aluminium zinc plated steel has a long service life of 30-50 years with very low maintenance costs.
Application Areas of Aluzinc Sheet
Aluzinc Sheet is widely used in Construction & Architecture, Automotive & Transport, Agriculture, Infrastructure, Manufacturing, and Appliances due to its excellent physical and chemical properties.
- Roofing and cladding: residential, commercial, and industrial buildings.
- HVAC systems: ducting and ventilation components
- Solar panel installation
- Vehicle components: body panels, chassis and exhaust systems
- Containers
- Greenhouses and silos
- Bridges and motorways
- Domestic appliances: refrigerators, ovens, and washing machines.
- Industrial equipment: machine guards, tanks, and conveyor systems.

Comparison of GI sheet, GL Sheet
Galvanized steel and galvalume steel are two popular metal sheets that are widely used in roofing, facades, and manufacturing. For corrosion and weathering resistance, aluzinc sheet (GL sheet) is the way to go, while GI sheet is a good choice for projects with limited budgets and less corrosive environments.
| Feature | Aluzinc (GL) | Galvanized Steel (GI) |
| Corrosion Resistance | 2–4x higher | Moderate |
| Heat Resistance | Up to 315°C | Up to 200°C |
| Lifespan | 30–50 years | 15–25 years |
| Cost | Slightly higher upfront cost | Lower initial cost |
| Best For | Harsh environments, long-term projects | Mild climates, short-term use |

How to Choose the Right Aluzinc Sheet?
The thickness of the aluzinc coating will affect the corrosion resistance of the sheet, the thickness of the sheet determines its workability and structural support ability, therefore, when choosing the aluzinc sheet, we have to consider the application environment, the coating thickness, the size of the sheet, the mechanical properties, the surface quality, the fire protection requirements, and many other factors.
- Environment: In coastal or industrial areas, choose a higher coating weight (e.g. 150g/m²).
- Coating type: use with PVDF or SMP coatings (PPGL) to increase UV resistance.
- Thickness: Choose 0.5mm-0.7mm for roofing or 1.0mm+ for structural applications.
