At ESG we have a hot-dip galvanising, shot blasting and passivation plant specially designed to meet the needs of all our customers. We ensure efficient and careful material handling, optimising the quality and physical condition of the parts.
We have a tank of 3m (length) x 1m (width) x 1.50 (depth), equipped with centrifuge system and specialised for the galvanising of:
- Screws
- Chain
- Tips
- Fittings
- Bolts
- Threaded rod
The Hot Dip Galvanising facility is equipped with shot blasting, centrifuging and passivation machinery, which allows us to achieve the necessary finishes according to the customer's needs, whether they are automotive parts, tips, screws and special parts.
Thanks to the LABORATORY AND QUALITY CONTROL products are constantly monitored in the areas of degreasing, pickling, etching, vat of galvanising, centrifugation y passivation.
Complying with the standard UNE- EN ISO 1461:2010the hot-dip galvanising division has the most complete technical-chemical systems that guarantee the best results in the galvanising process. high level of finish and quality.
In its quest for sustainability we are pleased to inform that ESG has been awarded by the Certification Committee for the general galvanisation of ferrous metals by immersion in molten zinc the quality and sustainability certificate of the mark ATEG.
