Product Highlights

1) High Strength & High Toughness in Combination
This design integrates high‑strength steel with hot‑stamped steel. The hot‑stamped sections deliver excellent strength and crashworthiness, effectively absorbing and dissipating impact energy during a collision to protect occupants. The high‑strength steel portions provide the side rails with superior toughness, enhancing fatigue resistance and enabling the side rails to better withstand dynamic loads experienced during normal vehicle operation.

2) Lightweight Construction
Without compromising strength, the use of hot‑stamped high‑strength steel allows for thinner material thicknesses, achieving significant vehicle lightweighting. Compared with conventional steel side rails, this hot‑stamped high‑strength steel solution reduces weight by approximately 20%–30%.

3) Cost Efficiency
By strategically selecting materials – hot‑stamped steel for critical zones and high‑strength steel for other areas – we achieve effective structural reinforcement while maintaining tight control over overall manufacturing costs.
