G.B.N. has the structure to process many alternatives of material based on steel matrix: in this way it can realise a very wide range of profi les suitable to the most different needs of its customers. The realisation happens by means of cold forming, due to the progressive action of a series of rollers which deform progressivelythe start lamina till obtaining the desired profi le as complex as it may be.
G.B.N. uses the following steel variants with low carbon content for deep drawing or cold bending.
