The choice of the materials making up the bodyshell is directed at achieving an excellent standard of quality in order to offer a quality product which is practical and long lasting.

45% of the weight of the bodyshell components is made from bi-galvanized metal, whit another 15% in weight is made from mono-galvanized metal.

Galvanized panels make up 90% of the total value of the body panels.

The galvanizing takes place in accordance with different technological processes:

  • deposition through a galvanizing process, the panel is immersed in or comes into contact with a salt bath, depending on whether bi-galvanizing or galvanizing is involved, which results in a high degree of surface finish;
  • fire deposition: the melted zinc is deposited thermally on the panel. With this process, which is used mainly for structural elements of the bodyshell, thicknesses of up to 20 micron are achieved, compared with the 7 micron obtained from the galvanizing process.

The protection of all the box sections is achieved using galvanized body panels which, after painting, are sprayed on the inside with wax based oil to prevent the phenomenon of internal oxidation.
