SGLCC Galvalume Steel Coil: Reliable Protection for Industrial Environments
Selecting the right material for industrial applications requires a balance of strength, corrosion resistance, and long-term value. SGLCC hot-dipped galvalume steel coil with AZ30-AZ275 coating is designed to meet these demands across sectors such as construction, agriculture, automotive, and general industry.
This product starts with a cold-rolled steel core that is hot-dipped into a 55% aluminum, 43.5% zinc, and 1.5% silicon alloy. The result is a dual-action protective layer: aluminum forms a strong barrier against rust, while zinc offers sacrificial protection at scratches or cut edges. This makes galvalume steel a dependable choice for both outdoor and harsh indoor environments.
