hot-dip galvanised
Galvanised fasteners

ESG

Elementos de Sujeción Galvanizados (ESG) is the division within the Apellániz Group dedicated to the design and manufacture of metal fittings, specialising in three fundamental aspects: metal transformation, robotised welding and hot-dip galvanising.

Our metal transformation systems for sheet metal formats, sheet metal coil strips, tubes, corrugated, rods and hot rolled profiles through automatic and manual press lines, automatic cutting machines, threading machines, 3D bending machines, laser cutting, welding robots, manual welding etc... oriented either in the construction industry, automotive, road safety, solar, life lines, automotive, telecommunications, railway, civil engineering, electrical or any other field.

Hot-dip galvanising, carried out in our own plant, is an essential process that gives metal fittings a protective layer of zinc, which makes them highly resistant to corrosion and gives them exceptional durability. This process guarantees a higher quality of products.

Our approval by leading companies in a variety of sectors is testament to our ability to meet their exacting standards. This demonstrates ESG's dedication to strictly follow each customer's specifications, ensuring the delivery of parts that meet the highest levels of quality.

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.
