ABSTRACT:
A method of manufacturing an improved doorbeam having increased impact strength and reduced weight. The doorbeam is formed from a continuous metal web having opposing lateral edges and a varying thickness therebetween. 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.
