SS400: Basic carbon structural steel, tensile strength ≥400MPa, suitable for general building frames and mechanical parts, cost-effective. SS490: Medium-strength steel (tensile strength ≥490MPa), balancing strength and cost in bridges and plant structures. SS540: High-strength steel (tensile strength ≥540MPa), suitable for heavy-load structures (such as high-rise buildings, port machinery), reducing weight while improving safety.
I-shaped steel has wide flanges and strong bearing capacity, and thin and tough webs. This design can provide sufficient support area to ensure the stability and reliability of the overall structure. It uses I-shaped flat steel that is thin in the middle and thick on both sides, which optimizes the force structure of the steel and enhances the overall strength.
High material utilization rate, suitable for industrial mass production, reducing overall costs; some models can replace concrete structures and shorten construction period
Under most environmental conditions, Q235B I beam exhibits good corrosion resistance and can resist a certain degree of oxidation and corrosion, extending the service life and safety of steel. However, in corrosive media such as strong acids and alkalis, corresponding protective measures need to be taken.
SS400 - SS490 Structural Steel I Beam 20a is available in various specifications in China, with lengths of 6 - 12m, thicknesses of 8 - 28mm, 6 - 16mm, etc., and web widths of 100 - 900mm, which can also be customized. There are carbon steel I-beams of different sizes such as 200200mm, 300300mm, etc., to meet different construction needs
Multi-type production adaptation: It can be applied to various models such as Morgan, Danieli, Pomini, and SMS, with performance and life better than the original equipment manufacturers, and can meet the needs of different production equipment1. High reference value of advanced technology: The development of low-temperature rolling technology for bars and wires provides a useful reference for further application of low-temperature rolling technology in domestic bar and wire production, which helps to optimize the production process
