Galvanized square tube

Square steel pipe is a lightweight hollow section steel with a square cross-section, widely used in structural engineering such as construction and manufacturing. Square steel pipe, as the name suggests, is a type of steel pipe with a square cross-section, belonging to cold-bent steel. It is made from hot-rolled or cold-rolled strip steel such as Q235, Q345, etc., and goes through processes such as unbundling leveling, curling, and welding into round pipes. Then, it is formed into a square shape through the rolling process and finally cut into the required length.1. Due its high strength and rigidity, as well as its neat and beautiful appearance, it has become one of the indispensable basic materials in the modern industrial and construction fields.5 Core and advantages High strength and good rigidity: suitable for bearing large loads and applicable to important structural components. Lightweight design: saves more material and reduces overall weight compared solid steel. Good corrosion resistance (especially for galvanized or stainless steel material): can be used for a long time in humid or outdoor environments. Easy to process: a variety of secondary processing methods such as cutting, welding, and bending. Smooth surface, easy to paint: enhances decoration and protective performance.5 Common specifications and standardsSquare steel pipes come in a variety of sizes and can be customized according to different needs. The following is a summary of the common specification range: Classification Dimension pecific Content Cross-section size Square: 8×8 mm to 800×800 mm; Rectangular: 10×20 to 600×800 mm 22 Wall thickness range 0.6 mm – 35 mm 10 Common material Q23, Q235B, Q345B, Q355B, 304 stainless steel, 510L, 15Cr, etc. Production process Welded square steel pipe (high-frequency welding), seamless square steel pipe, hot-rolled/cold-drawn square steel pipe25 Executing standard GB/T 6728-2002 (National standard), JIS G3466-88 (J standard), EN 10210 (European standard), etc. When purchasing in practice, it is necessary to pay attention to the manufacturer's tolerance difference ensure the interface matches.
