FAQ โ Aluzinc Steel Coil
Aluzinc steel coil is a cold-rolled steel coil coated with an aluminum-zinc alloy layer through a hot-dip process. The coating typically contains 55% aluminum, 43.4% zinc, and 1.6% silicon, providing excellent corrosion resistance and heat reflectivity.
Aluzinc steel coil is widely used in:
-
Roofing sheet manufacturing
-
Wall cladding systems
-
Sandwich panel production
-
Industrial buildings and warehouses
-
Agricultural structures
-
Steel structures and construction components
-
HVAC ducts and ventilation systems
It is commonly used in long-life roofing and construction materials.
-
Galvanized Steel (GI): Zinc coating, lower cost, good corrosion resistance.
-
Aluzinc Steel (GL): Aluminum + Zinc alloy coating, higher corrosion resistance and heat reflectivity.
Aluzinc steel can last 2โ4 times longer than galvanized steel in certain environments.
Common coating weights include:
-
AZ30: Indoor applications
-
AZ50: General construction
-
AZ100: Standard roofing
-
AZ150: High corrosion resistance
AZ150 is the most widely used coating for roofing sheet production.
Typical thickness range:
-
0.12 โ 0.25 mm: Roofing sheet manufacturing
-
0.30 โ 0.50 mm: Industrial roofing and cladding
-
0.50 โ 1.0 mm: Structural panels
-
1.0 โ 2.0 mm: Industrial fabrication
Custom thickness can be produced according to customer requirements.

-
1000 mm: General sheet processing
-
1200 mm: Panel manufacturing
-
1250 mm: Construction applications
Custom slitting widths are also available.
Aluzinc steel is widely used for roofing because it provides:
-
Superior corrosion resistance
-
Excellent heat reflection
-
Long service life
-
High durability in harsh environments
-
Lower maintenance costs
Yes. Aluzinc steel coil is commonly used as the base material for PPGL (Pre-painted Galvalume Steel Coil). After cleaning and chemical treatment, the coil is coated with paint to produce color coated steel for roofing and wall panels.
Service life depends on coating weight and environment. Typical lifespan:
-
Rural environment: 25โ40 years
-
Industrial environment: 20โ30 years
-
Coastal areas: 15โ25 years
Higher coating weights provide better corrosion protection.
