1. Main forming methods for flat products

Let's take a closer look at the different types of formable sheet, in the broadest sense of the word.

Let's begin by classifying, very roughly and for average application conditions, the main flat product forming methods in order of increasing difficulty, both in terms of ductility requirements and complexity of implementation:

• bending (see article Heavy plate forming [BM 6 560] );

• folding (see article
