AZ100 Aluzinc Steel Roll Forming Material Guide: Coating Thickness, Coil Sizes & Uses

AZ100 Aluzinc Steel Roll Forming Material

1. Overview of AZ100 Aluzinc Steel in Roll Forming

AZ100 Aluzinc steel is a medium aluminum-zinc coated steel with a coating weight of 100 g/m² (total both sides). It offers a balanced combination of corrosion resistance, heat reflectivity, and cost, making it suitable for both indoor and light outdoor applications.

The coating consists of 55% aluminum, 43.4% zinc, and 1.6% silicon, providing improved durability compared to AZ50 while remaining more affordable than AZ150.

In roll forming, AZ100 is commonly used in roofing, wall cladding, and light structural components where moderate corrosion protection is required.
