High-strength Roll-formed Products

Leveraging its deep technical expertise in precision metal forming, Shanghai Heda has established high‑strength roll forming as the core process route for lightweight and safety‑critical structural components in automotive body applications. We specialize in roll forming of advanced high‑strength steels ranging from 590 MPa to 1500 MPa, with products widely covering front/rear bumper beams, rocker panel reinforcements, seat frames, and battery pack side rails.

Compared with conventional stamping processes, our roll‑formed products feature closed multi‑cavity sections produced through multi‑pass continuous rolling. This delivers a 15%–25% weight reduction while significantly improving bending/torsional stiffness and fatigue life. With a material utilization rate exceeding 95%, extremely low die amortization costs, and high dimensional precision, Shanghai Heda's high‑strength roll‑forming solutions achieve the optimal balance between “extreme lightweighting” and “lowest total cost.” Our solutions have been successfully adopted by leading domestic and international OEMs, contributing to improved vehicle safety ratings and weight reduction for electrified platforms.

Looking ahead, Heda is actively developing next‑generation TRB (Tailor Rolled Blank) roll‑forming technology, which employs variable material thickness to achieve further weight reduction at the same cost level.
