The GSB AL 631 Quality Regulations apply to the coating of components made from aluminium and its alloys, which are used in structural engineering. The GSB ST 663 Quality Regulations apply to non-galvanised steel surfaces, continuously hot-dip coated flat steel (EN 10346) and hot-dip galvanised steel (ISO 1461, single-piece galvanisation) used in structural engineering.
Coatings are applied to semi-finished products, semi-finished and finished components and pre-fabricated constructions before they are installed. Only products that are checked and approved in accordance with these guidelines are used to pre-treat surfaces and produce coatings.
As part of these quality checks, our inspectors not only review the comprehensive programme of self-auditing and documentation measures, they also take profiles and subject them to the prescribed corrosion tests in our accredited laboratory.
Only approved coating systems are permitted for the coatings. The approval of coating materials is carried out in our laboratory.
