Production Process
Galvanized Square Tube
A galvanized square tube is a hollow structural steel tube with a square cross-section that has been coated with a layer of zinc to provide corrosion resistance. The galvanization process can be hot-dip galvanizing or pre-galvanizing (cold galvanizing). This protective zinc coating extends the tube’s service life, making it ideal for outdoor, exposed, or corrosive environments.
Product Description
High Strength and Structural Integrity
Rectangular steel pipes have higher bending and torsional resistance compared to round pipes in certain applications.Ideal for load-bearing structures and frameworks requiring superior strength and stiffness. Easy Welding and Fabrication
Flat surfaces make welding, bolting, and joining easier than round pipes.Simplifies assembly in modular and prefabricated structures.
Excellent Durability and Corrosion Resistance
Made from high-quality carbon steel or alloy steel, with options for galvanized coating for corrosion protection.Ensures long service life even in outdoor or harsh environments.
