AZ30 Galvalume Steel Coil (30 g/m²)
Durable AZ30 Galvalume steel with superior corrosion resistance, excellent heat reflectivity, and versatile applications for construction, automotive, and appliances.
Galvalume Steel Coil AZ30 (30 g/m²) – High-Performance Aluzinc Coated Steel
Galvalume Steel Coil AZ30 (30 g/m²) refers to an Aluzinc-coated steel coil with a total coating weight of 30 grams per square meter. The coating is composed of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon, which provides superior corrosion resistance, excellent thermal stability, and outstanding reflectivity compared with conventional galvanized steel.
Thanks to its unique metallurgical structure, Galvalume AZ30 combines the barrier protection of aluminum with the galvanic protection of zinc, making it a cost-effective material for construction, automotive, home appliances, and industrial applications.
Key Features
- Superior Corrosion Resistance
AZ30 Galvalume steel offers 3–6 times longer service life than traditional galvanized steel under similar conditions. The aluminum oxide layer acts as a durable barrier, while zinc provides sacrificial protection. - Excellent Heat and Light Reflectivity
The material withstands continuous exposure up to 300–315 °C and reflects heat and UV radiation almost twice as effectively as galvanized steel, reducing energy absorption. - Lightweight yet Strong
With a lower coating density than pure zinc, AZ30 provides wider surface coverage with less material. It ensures excellent workability, including stamping, cutting, bending, welding, and profiling.
