Body Construction and Material Repair Guidelines: General Motors

What is the MPa of the front lower rail? What is the outer uniside made of: steel, aluminum, or composite? Can heat be used to straighten or is it cold straightening only? What are the repair limitations? These are just some of the questions that the RTS team fields on a daily basis.

As we know, today’s vehicles can be constructed from a wide variety of materials. Knowing if the OEM provides information on body construction materials and repair guidelines is a crucial step in providing a complete, safe, and quality repair. Let’s see what General Motors (GM) has to say.

GM provides a construction material breakdown on various vehicle components. The information is located in vehicle-specific body repair manuals under Body Repair > Visual Identification > Structure Identification. This section will typically have a numbered vehicle illustration with a corresponding table. The table shows if there is a procedure available and what the construction material is. A detailed description of the various steels, including the MPa range, used by GM is located in the body repair manual under Description and Operation. Additional repair guidelines are also available on the Recommended GM Steel Reparability Matrix
