ESG

Elementos de Sujeción Galvanizados (ESG) es la división dentro del Apellániz Group dedicada al diseño y fabricación de herrajes metálicos, siendo especialistas en tres aspectos fundamentales: transformación metálica, soldadura robotizada y galvanizado en caliente.

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.

The hot-dip galvanised, realizado en nuestra planta propia, es un proceso esencial que confiere a los herrajes metálicos una capa protectora de zinc, lo que los hace altamente resistentes a la corrosión y les otorga una durabilidad excepcional. Este procedimiento garantiza una mayor calidad en los productos.

Nuestra homologación por parte de empresas líderes en diversos sectores es testimonio de nuestra capacidad para cumplir con sus estándares más exigentes. Esto demuestra la dedicación de Elementos de Sujeción Galvanizados (ESG) a seguir estrictamente las especificaciones de cada cliente, asegurando la entrega de piezas que cumplen con los más altos niveles de calidad.

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.
