Steel structure of common materials used

Now the use of steel structure of demand is higher and higher, therefore the adoption of the steel structure of material requirement also more and more high, on the use of steel structure, we mainly adopt what material to use, according to the different use, the different components, the use of material is also different. Main component class material: 1, the blade plate: 8 - thick 32. Wide 180 - 600. 15000 the following long. 2, rolled plate: open tablet, kaiping pattern plate. In general, 1250 wide. 1500. 1800. 2000. Thickness is 16. 3, hot rolling of thick plate. 4, H section steel, hot-rolled h-beam, high-frequency welding h-beam. Time component class material: 1, i-steel, channel steel, Angle steel, Equal and unequal) , round steel, rebar, cold bending hollow section 2:3 square tubes, rectangular tubes, pipe, high-frequency welded pipe, heat expansion of seamless pipe, seamless tube, spiral pipe delivery time is 15 -- 45 days, diameter of 219 above, below the wall thickness is 16. 30 - straight seam submerged arc welding pipe 45 days, more than 400 diameter, wall thickness as below 50. Retaining class material: 1, purlin, have wide roll slitting or repression and galvanized steel strip: wuxi ( Strip) Black (such as The galvanized) : wide volume ( MeiGang, wuhan, anshan, benxi steel, etc. ) And strip ( Tianjin rolling a, tangshan stainless, etc. ) , 2, lottery Numbers: regular substrate thickness ( 0. 35. 0. 40. 0. 50. 0. 55. 0. 6) Conventional color ( Sea blue, white, ivory, etc. ) 。 3, aluminium zinc plate: origin of baosteel ( MeiGang) Bluescope, joint, etc. 4, galvanized sheet, thickness below 3, 1000. 1250. 1500, etc. Origin of masteel, tangsteel, benxi steel and so on. 1, stainless steel: conventional thickness. 0, 1. 2, 1. 5, the regular 1000. 1220. 1240.
