Applications and Industries
Finishing, Quality and Packaging
Finishes such as passivation, plating, galvanizing or customer-specified treatments are selected to suit the material and service. Inspection may include dimensional, visual, mechanical and chemical checks, PMI where applicable, and Material Test Certificates (EN 10204 3.1 where requested). Goods are packed for export.
