Other building steel and steel specifications basic introduction

Other building steel

In some cases, to use some different grades of steel, the material should meet the relevant national standards. For example, when the welded load-bearing structure uses Z-directional steel to prevent lamellar tearing of steel, it should comply with the provisions of the Thickness Direction Performance Steel Plate (GB/T5313) : In the exposed environment has special requirements for corrosion resistance or under the action of corrosive gas, solid medium bearing structure using weathering steel, should meet the provisions of the "welding structure weathering steel" (GB/T4172) : When the steel structure is used, should meet the provisions of the "General engineering cast carbon steel parts" (GB/T11352).

Steel specification

The steel used in steel structure is mainly hot rolled steel sheet, section steel and steel pipe, and cold rolled steel sheet and cold formed thin-wall steel. In order to reduce the production workload and reduce the cost, the design of steel structures and producers should have a more comprehensive understanding of the specifications of steel.
