ULTRA HIGH-TENSION STEEL [CONSTRUCTION]

• Ultra high-tensile steel plates have enhanced tensile strength compared to previous high-tensile steel plates.

• Because the strength is maintained even though the plates are thin-walled, the ultra high-tensile steel plates are used for the frames and the main frame parts which form the cabin, reducing the weight of the vehicle.

• Enhanced shock absorption has improved the safety.

• Because the ultra high-tensile steel is hard and it may be difficult to reform, when extracting the damaged part using a frame repair machine, perform the work verifying that other parts are not affected.

• When drilling welded parts, use a well-ground drill bit.

• After welding, inspect the weld strength. If adhesion is poor, perform arc welding (plug welding).
