Square and rectangular tubes are industrial consumables, which generally involve large quantities of procurement. The procurement personnel also need to sort out relevant data during procurement. The above customized standards of seamless square and rectangular tubes manufacturers and the specification and size table of square and rectangular tubes can provide reference for procurement personnel, and more direct data will be generally provided by manufacturers.
01 Tensile, compressive and shear resistance of steel
The tensile, compressive and shear strength of steel is relatively high, and the section of steel members is small and the dead weight is light. High strength, suitable for building bridges with heavy loads; Light deadweight can reduce the load of the foundation, reduce the cost of the foundation, and facilitate transportation and hoisting.
- 02 Good plasticity and toughness of steel
The good plasticity and toughness of steel make the seismic performance of steel structure bridges good. Because steel has good plasticity and toughness, it can absorb more energy through the deformation of the structure under the earthquake action, and has the toughness that can act repeatedly, thus greatly improving the seismic performance of the steel structure. Earthquake resistance and wind resistance are the guarantee of bridge safety. The excellent seismic performance of steel structure bridges expands their application scope, especially in high seismic intensity areas.
