PRODUCT DESCRIPTION

1. Classification of production process of galvanized steel square rectangular tube
According to the production process, rectangular tubes are divided into hot rolled rectangular seamless steel pipe, cold drawn rectangular seamless steel pipes, extruded seamless rectangular tubes and welded rectangular tubes. 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 welding points Minute
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 shapes
Square tubes are classified according to cross-sectional shape: (1) Square steel pipe 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
5. Classification of surface treatment of rectangular tubes
Square tubes are divided into hot-dip galvanized square tubes, electro-galvanized square steel pipes, 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
