Hot-dip galvanising process

In compliance with the UNE- EN ISO 1461:2010 standard, and in order to achieve maximum cleanliness throughout the process and to ensure perfect adherence of the coating, the galvanising division has the most complete technical-chemical systems that guarantee its high level of finish. The installation is equipped with a specific centrifugation area, which allows the galvanising of chains, automotive parts, tips, screws and any threaded part, however demanding it may be.

Thanks to our own LABORATORY AND QUALITY CONTROL, products are constantly monitored in the pickling area, baths and galvanised parts.
