I-CAR · July 16, 2021
Summary
This article outlines the fundamentals of cold straightening, which is the process of repairing metal damage without heat using methods like hammer and dolly, PDR, or structural pulling. It emphasizes that certain materials like aluminum and UHSS are prone to cracking during cold straightening and highlights that heat should only be applied if explicitly permitted by the vehicle manufacturer.
What to do on the job
Always verify the vehicle manufacturer's specific guidelines regarding cold straightening and heat application limits for the specific metal type before attempting any metal repair.
How to use it
Use this document to justify the replacement of structural or cosmetic parts when the OEM prohibits cold straightening or the application of heat on the specific metal type (such as UHSS or aluminum) involved in the collision.
