Steel profile

high strength steelspecialfor the automotive industry

Overview
Higher strength and greater durability from lower weight. Welser Profile offers roll-formed metal section solutions tailored to automotive applications, developed in collaboration with customers to maximise design potential and manufacturability.

Your benefits

• Excellent strength, rigidity and dimensional accuracy
• Superior deformation behavior in crash tests
• Rapid prototyping with near-series production properties
• Weight savings using high-strength and ultra-high-strength steels with reduced gauge and further optimisation options
• Tight tolerances for precision joining techniques and high safety requirements
• High residual elongation and optimal radii achieved through material-friendly roll forming
• Cost reduction by near‑net‑shape profile cross-section design

Applications

• Crash structures and impact elements
• Seating components and seat rails
• Sills and rocker panels
• Reinforcing beams, longitudinal members and crossmembers
• Guide and mounting rails
• Aluminium or steel tubes for hydroforming
• Seat structure tubes and assemblies
