Advantage of high strength steel in ordinary steel

Compared with lowbed trailer ordinary-strength steel, lowbed trailerhigh-strength steel has higher yield strength and tensile strength. Therefore, using high-strength steel components to replace ordinary-strength steel components can reduce the section size, save steel consumption, and reduce manufacturing, transportation, and installation costs. The application of high-strength steel can not only reflect higher structural efficiency, but also bring considerable economic and social benefits.

There are many advantages of lowbed trailer high-strength steel. The research results show that under the same axial compression condition, the steel column using high-strength steel will have the ratio of ultimate stress δu to yield strength fy in terms of overall stability δu/fy (that is, the overall stability. The stability coefficient φ) is much higher than that of ordinary strength steel columns.

Compared with lowbed trailer ordinary steel, the use of lowbed trailer high-strength steel for steel structures has the following advantages: it can reduce component size and structural weight, correspondingly reduce welding workload and welding material consumption, and reduce the amount of various coatings (rust-proof, fire-proof, etc.), It makes the transportation and installation easier, and reduces the processing, production, transportation and installation costs of the steel structure. lowbed trailer High-strength steel can reduce the amount of steel, thereby greatly reducing the consumption of iron ore resources; the reduction in the amount of welding materials and various coatings (rust-proof, fire-proof, etc.) can also greatly reduce the consumption of non-renewable resources and reduce Damage to the environment from resource extraction.
