Square Structural Steel Pipe

Square tube if deduce ChengFangGang, dug solid part is a square tube, and then its mechanical properties and physical properties and may be, compare the channel steel, i-steel, what are the advantages? Mechanical performance analysis, we use 200 * 200 mm square tube, wall thickness, arbitrary choice as case analysis, the direct compression section is 400 ㎡, and beams, channels direct compression fracture compared with square tube, are incomplete, the parameters of the compression of vertical section, square tube than beams and channels, if as a straight column in structural steel pipe, the stress of the square tube performance than beams and channels. Square tube is chosen as the pillar is best choice on mechanical design Physical performance analysis: 1. The square tube and antirust processing, the surface is smooth, easy spraying, spraying the surface just ok, and beams and channels need to deal with the double rust; 2. Square tube section without the imperfect part, channel and I beam section are vacant; 3. The square tube welding process, welding around as long as the appearance, more convenient, reliable, and the channel steel, i-steel, outside welding; 4. Galvanized square structural steel pipe factory has made the anticorrosive, antirust processing, don't need to make other processing, purchase and can be used. Based on the comparison of the above reasons, the physical properties of the square tube compressive capacity are better than that of the channel and I beam. According to the mechanical and physical performance analysis, large steel structure using the square tube, save material, energy saving, structure, strong square tube inevitably in steel structure of the future is bound to replace beams and channels.
