These plates can be made of aluminium, stainless steel and plastic materials such as PVC, polyurethane and even methacrylate.
Some companies, in addition to using identification by textile labels, such as embroidery, thermo-adhesives or tex-flex labels, use this type of plates that are usually placed on the chest by means of a safety pin or pin placed on the back of the plate.
Regardless of the work identification, companies use them as a reference for the projects, installations or assemblies they carry out.
