Welded structure
Use hot-rolled steel (angle steel, I-beam, channel steel, steel pipe, etc., steel plate, cold-formed thin-walled steel and steel wire as basic components, and connect them by welding, bolting or rivet connection according to certain rules After the basic member is formed, the basic member is irregularly connected into a structure capable of withstanding external loads as a steel structure by welding, bolting or rivet connection.

The welding structure has a series of advantages that other structures can not compare, mainly reflected in the following aspects:Please check the word document below
