The tolerances applicable for control are those shown on this page except when a FAI, a DVI, or a specific control document
are requested to GETELEC.

All our sheets are individually checked and given certificates of conformity. Each type of sheet can be made
on request in a fire-resistant version (according to UL 94). We can also provide cut sections to suit the most
appropriate procedure for your requirements : Tool cut, laser cut, water jet cut and flash cut.
