W18x283 h shaped steel beam material and process
1. Optional materials include A36 carbon steel, A572GR50 and A992 high-strength low-alloy steel.
2. It is formed by hot rolling process. Compared with welded H-shaped steel, it has higher material utilization and better structural uniformity, which is suitable for buildings in earthquake zones.
W18x283 h beam profile Application scenarios
High-rise buildings and industrial facilities: As main beams and shear wall frame columns, suitable for large-span structures (such as factory roof support); used for heavy equipment foundation support or crane track beams, withstanding long-term vibration and fatigue loads68. Bridge engineering: As main beams or bridge pier components, it adapts to vehicle dynamic loads and wind loads, and reduces the risk of laminar tearing.
Economic efficiency and selection recommendations
Compared with ordinary welded H-beams, the hot rolling process reduces material waste and reduces the initial cost by 15%-20%.
It is recommended to select the material according to the load requirements: A36 is used for general static load scenarios; A992 is suitable for seismic areas or high dynamic load scenarios.
