WHAT ARE YOU LOOKING FOR?
Roll-formed automotive high strength steel parts are fabricated by progressively bending continuous steel coils into complex closed or open sections (hat, "B", or "C" profiles) at ambient temperature. Unlike stamping, which often requires trimming and generates significant scrap, roll forming produces net-shape or near-net-shape profiles with minimal material waste, making it ideal for high-volume production of long, straight structural members.
Mass Reduction: Utilizes high-tensile steels (up to 1500 MPa) to reduce component gauge and overall vehicle weight, contributing to fuel efficiency and EV range extension.
Structural Integrity: Continuous grain flow along the profile length enhances fatigue resistance and energy absorption during collisions.
Dimensional Stability: High-precision profiles (tolerance ±0.1mm) ensure perfect fitment with Body-in-White (BIW) assemblies.
Complex Geometries: Capable of forming deep channels, multiple bends, and variable cross-sections in a single pass.
We are looking forward to working with you. Please feel free to contact us if you have any inquiry.
