High-strength Crash Beams / Sill Beams

As a core supplier in the field of automotive passive safety, Shanghai Heda is dedicated to providing OEMs with full‑scenario safety structural solutions covering frontal/rear impacts and side protection. Our product portfolio includes lightweight aluminum alloy bumper beams, 1500 MPa‑grade high‑strength steel roll‑formed bumper beams, and hot‑stamped rocker panels, underpinned by end‑to‑end capabilities spanning material R&D to precision manufacturing.

For frontal and rear crash systems, we employ 6xxx‑ and 7xxx‑series aluminum alloy extrusions, as well as high‑strength steel roll forming and hot stamping. Through topology‑optimized multi‑cavity closed‑section designs, we achieve outstanding bending stiffness while delivering extreme weight reduction – the aluminum solutions offer over 40% weight savings compared to steel counterparts – without compromising low‑speed crash repairability.

For the side‑impact critical rocker panels, we focus on Heda's proprietary ultra‑high‑strength 6xxx‑series aluminum alloy, which exhibits yield strength far superior to conventional 6xxx alloys, creating an impenetrable side defense line. Under C‑NCAP / Euro NCAP side‑pole impact and rollover conditions, this design effectively controls occupant cabin intrusion, ensuring the safety of both passengers and the high‑voltage battery pack.
