Before cutting or welding For additional information, refer to Specifications (501-25 Body Repair - General Information, Specifications).
Bumper Beams
Bumper beams are usually manufactured from HS (high strength) or stronger steel. If the bumper beam shows signs of kinking or tearing, it is not repairable and must be replaced. Do not use heat to straighten these components, as it will weaken the component. Minor damage is repaired by cold straightening only.
