Products Description
20mm x 20mm x 1.2mm hot-dipped galvanized square tube is a premium-quality steel profile designed for superior strength, excellent corrosion resistance, and long-lasting durability. Manufactured from high-grade mild steel, this tube undergoes a rigorous hot-dip galvanizing process, creating a robust zinc coating that protects it from rust, corrosion, and harsh weather conditions. It is the ideal choice for a wide range of structural, industrial, and decorative projects.
