摘要 |
A method of manufacturing an improved doorbeam having increased impact strength and reduced weight.

The stock is rolled into a tubular configuration, and the lateral edges are welded together. The resultant beam provides extra reinforcing material where needed to provide a balance between weight and strength. |
