PRODUCT DESCRIPTION

Galvanized square steel tube is a general term for square steel tubes and rectangular tubes, that is, steel tubes with equal side lengths. It is made of strip steel after process treatment and rolling. Generally, the strip steel is unpacked, leveled, crimped, welded into round tubes, rolled into square tubes, and then cut into required lengths. Generally 50 pieces per pack. Also known as square, rectangular cold-formed hollow section steel, referred to as square tube, rectangular tube.

1. Classification of square and rectangular tube production process
Square rectangular tubes are divided into hot-rolled seamless square steel pipes, cold-drawn seamless square steel pipe, extruded seamless square tubes and welded square tubes according to the production process. Welded square tubes are divided into: (a) arc welded square tubes, resistance welded square tubes (high frequency and low frequency), gas welded square tubes and furnace welded square tubes; (b) straight seam welded square tubes and spiral welded square tubes according to Weld points
2. Material classification of square and rectangular tubes
Square tubes are divided into plain carbon steel square tubes and low alloy square tubes according to their materials. Ordinary carbon steel is divided into Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.; low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
3. Classification of square and rectangular tube production standards
Square tubes are divided into national standard square tubes, Japanese standard square tubes, British standard square tubes, American standard square tubes, European standard square tubes and non-standard square tubes according to production standards.
4. Classification of rectangular tube section shape
Square tubes are classified according to the cross-sectional shape: (1) Square tubes with simple cross-sections - square square tubes, rectangular square tubes (2) Square tubes with complex cross-sections - flower-shaped square tubes, open-shaped square tubes, corrugated square tubes, special-shaped square tubes Tube
5. Classification of surface treatment of rectangular tubes
Square tubes are divided into hot-dip galvanized square tubes, electro-galvanized square tubes, oil-coated square tubes and pickling square tubes according to surface treatment.
6. Classification of square and rectangular tubes
Square tubes are classified by use - decorative square tubes, machine tool equipment, machinery industry, chemical industry, steel structure, shipbuilding, automobiles, steel beams and columns, special-purpose square tubes
7. Wall thickness classification of square and rectangular tubes
Rectangular tubes are classified according to wall thickness - extra thick rectangular tubes, thick rectangular tubes and thin rectangular tubes
