It maintains underbody stiffness. It is connected behind front side member to absorb and transmit collision energy in front/offset collision and requires local stiffness and durability.

Mainly applied steel sheet has a tensile strength of 590~980MPa. However, steel which has maximum TS 1180MPa is recommended for lighter weight and better collision safety. The manufacturing process is mainly applied to Forming, Drawing or Roll forming.

It suppresses collision intrusion at frontal collision and transfers crash energy to rear. It also requires sufficient NVH(Noise, Vibration, Harshness) characteristics.

This component can minimize dash lower deformation upon high-speed impact to reduce driver injury.

Mainly applied steel sheet has a tensile strength of 340~980MPa. The manufacturing process is mainly applied to Drawing or Forming.

This component connects members with the body and requires sufficient strength of the cross section. The reinforcement back upper front requires sufficient mounting strength as a seat belt reactor can be connected while the reinforcement back upper rear requires sufficient torsional rigidity as it bears an interface with the rear window of the car.

Mainly applied steel sheet has a tensile strength of 260-590Mpa and a thickness of 0.7-1.2mm.The manufacturing process is mainly applied to Drawing or Forming.

This component constitutes the structure of a motor vehicle and requires optimal cross sectional rigidity and strength to minimize deformation upon frontal, offset or root impact.

Mainly applied steel sheet has a tensile strength of 340-1470Mpa and a thickness of 0.9-1.6mm.The manufacturing process is mainly applied to Drawing, forming or Hot press forming.

This component constitutes the structure of a motor vehicle and requires high strength as it has to absorb some of the shocks upon frontal or offset impact and transmit the rest to the side sill and the A-pillar. It also requires appropriate thickness because the cross section that it forms along with A-pillar lower inner determines the rigidity of the body (torsion, bending). It also requires high strength and rigidity at the location where the front door hinge is attached.

Mainly applied steel sheet has a tensile strength of 340-590Mpa and a thickness of 1.2-1.6mm. The manufacturing process is mainly applied to Drawing or Forming

This component is designed to disperse shock upon rear or offset impact and be deformed to absorb energy. In statutory testing, it serves as an impact member to minimize damage to its neighboring components. Optimal cross section, strength and thickness are the most important factors for this component as it works along with the crash box to absorb shock upon low and high-speed impact.

Mainly applied steel sheet has a tensile strength of 590 ~ 1470MPa and a thickness of 1.4 ~ 2.0mm. The manufacturing process is mainly applied to Hot press forming or Roll forming.
