High-Quality Cold Formed Steel Profiles

Welded Stainless Steel Pillar is a key customized structural part of the vehicle body side wall and door area of rail transit vehicles. As a core component connecting the vehicle body underframe and side wall, it plays an important role in transmitting vehicle body loads and strengthening vehicle body rigidity, and is widely used in the manufacturing of global subways, EMUs and low-floor trams. The product uses special shaped pipes and profiles as the base material, formed by precision cold bending process, and key stressed parts are strengthened by welding machining technology, with firm and flat welds, with the characteristics of high strength, lightweight and fatigue resistance, meeting the lightweight design trend of modern rail transit vehicles.   In the vehicle body structure, the welded stainless steel pillar cooperates precisely with components such as Door frame assembly and side beam to build a stable vehicle body stress frame, providing stable installation support for the do…
