Our fabrications can be complemented with different types of surface treatment or surface finishing. We apply these treatments under previous definition of the client and adapting to their needs or based on our own criteria always covering the client’s needs.

Surface treatment or surface finishing is defined as the set of different processes that give the manufactured metallic element a certain appearance or durability.

Surface treatments can consist of hot-dip galvanizing, plating, pre-preparation of the surface by shot blasting or pickling, painting, temporary surface protection or permanent surface protection. It is possible to use or apply individually or in combination different surface treatment processes to give our products aesthetics and/or durability.

We build componentsThe company has a wide range of products, subcomponents, elements or kits, for final products, production processes, maintenance, industrial tooling, construction, etc. Also main or secondary metallic structures for industry or construction.

These will normally be single assemblies or initial prototypes that require a medium-high level of quality, where the customer needs to be sure that all their specifications are met and demonstrable.


Production industry and industrial engineering.


We have ISO 9001 quality management certifications. supplemented to meet the criteria of 10 CFR 50 App B and ASME Section III Subsection NCA-3125 and NCA-4110(a). Subcontracted Services.
ISO 3834-2
quality of welding processes.
UNE-EN 1090 factory production control and CE marking.

We are technically capable of executing metallic structures in classes EXC 1, 2, 3 and 4 , being able, where appropriate, to carry out CE marking.


The “works control records sheet” included in the ISO 9001-2015 quality system indicates the type of inspection, frequency and incidents arising in the works, these parameters will be different in each work to be carried out, and may be supplemented by external audits in cases where required.

In the inspection points plan (IPP) of the work included in the quality system as required or for productions subject to UNE-EN 1090, indicates the type of inspection, frequency and incidents arising in the works, these parameters will be different in each work to be carried out, and may be supplemented by external audits where necessary.
