Now on the use of steel structure of the increasingly high demand, so the adoption of steel structure on the material requirements are also getting higher and higher, the use of steel structure, we mainly use what materials to use it, according to the different uses, different components, the use of materials are also different.
The main component class material:
Note: 1, plate thickness of 8-32. Wide 180-600. Long below 15000.
2, coil: open flat, Kaiping pattern plate. General 1250.1500.1800.2000 wide. Thickness is below 16.
3, hot rolling thick plate.
4, H type steel: hot rolled H steel, high-frequency welded H steel.
Component class of timber:
1, I-beam, channel steel, angle steel (equilateral, inequilateral, round steel, screw thread steel etc.)
2, cold formed steel hollow sections: a square pipe, rectangular pipe
3, the circular tube: high frequency welded pipe, thermal expansion of seamless pipe, seamless tube, spiral pipe delivery time is 15-45 days, 219 larger in diameter, wall thickness is below 16. Longitudinal submerged arc welded pipe diameter 30-45 days, more than 400, the wall thickness is below 50.
Enclosing class timber:
1, purlin: wide strip of coil strip or pressed
Galvanized: Wuxi (strip) etc.
Black (non Galvanized): wide roll (Mei Gang, Wuhan steel, Anshan, Benxi Iron and steel, strip steel etc.) (Tianjin No. 1, Tangshan stainless steel etc.),
In 2, the lottery: a conventional substrate thickness (0.35.0.40.0.50.0.55.0.6) and conventional color (Highland, lime, ivory etc.).
3, aluminum plating zinc plate: origin of Baosteel (Meishan) Bosq, joint etc.
4, galvanized plate thickness below 3, width 1000.1250.1500; origin of Maanshan Iron and steel, Benxi Iron and steel Tang Gang, etc..
5, stainless steel: conventional thickness 1 1.2,1.5, conventional 1000.1220.1240.
