Product Details
Designed for large steel structure construction projects, this bent welding steel frame adopts architectural-grade high-strength structural steel, matched with large-scale CNC bending technology to produce H-beams, box columns, corner supports and other structural components with integrated bending forming. The bending forming process ensures uniform stress distribution of steel components, greatly improving the overall stability and bearing capacity of steel structure buildings.
We strictly implement architectural steel structure welding standards, adopting automatic welding to ensure full and firm welds, with 100% non-destructive testing for key welds. The integrated bending design reduces on-site splicing workload, making construction more efficient and effectively lowering construction safety risks. Each frame component is processed and sized accurately, realizing seamless docking during on-site installation.
Aiming at outdoor building application environments, we provide professional anti-corrosion and anti-rust surface treatment, with optional sandblasting, hot-dip galvanizing and weather-resistant coating, adapting to outdoor wind, rain, exposure and other harsh conditions. We support drawing deepening and customized processing according to architectural construction drawings, fully meeting the design and acceptance standards of steel structure buildings.
