Description
Galvanized steel square tubes are hollow-section pipes with square profiles, treated by hot-dip or electro-galvanizing to enhance corrosion resistance and durability. Their smooth surface and structural integrity make them ideal for laser cutting, perforation, and precise welding—commonly used in construction, equipment frames, and light-gauge structures.
Key Features
Superior corrosion resistance with long-lasting zinc coating
Excellent structural stability with uniform load-bearing section
Laser-friendly flat surfaces and uniform wall thickness for clean cutting and welding
Flexible coating options: hot-dip or electro-galvanized
Applications
Structural frames, light-gauge steel construction
Automation equipment frames and machine bases
Display racks, partition systems, handrails
Laser-cut components and precision assemblies
Common Specifications
Item Range / Typical Values
Size 20×20 mm to 150×150 mm
Thickness 1.0 mm to 6.0 mm
