GSB's nationally and internationally established quality guidelines apply to coatings and alloys of components made from different materials, aluminium or steel. Not only the coaters but also the pre-treatment of the materials as well as the powder suppliers are checked for highest requirements.
When testing for the quality seal "GSB Premium Coater", the laboratory equipment as well as the factory production control are tested in addition to the manufacturing facility. However, already coated aluminium sheets and profiles are tested by the organization with the help of cooking tests, grid sections and measuring of layer thicknesses to the highest extent. The additional seal "Sea Proof" is also included in the certification as a premium coater. Here the parts are subjected to an acetic salt spray test as well as the filiform corrosion test (FFK). Particularly in areas with high salt content in the air - especially at the sea - such requirements are of great importance.
In order to be able to continue using the certificate, GSB will subject Solarlux to unannounced inspections of the required standards twice a year.
