built on our many years of working with industrial steel bolting and fastening systems for large customers, and we specialize in all types of metal industry-specific coatings.

Our main line business is the wholesale of bolts and fasteners, and we are currently leading the industry in Spain. We supply stainless steel and coated carbon steel parts to top construction, metal silo, greenhouse and solar panel companies, among others.

We owe our success to three key reasons: The quality of our products, our flawless consultancy service – always readily available for our customers, and our ongoing investment in innovation, continuously deploying cutting edge technology across our processes.

At SNK System, we aim to stand out from among our competitors in the bolting industry by staying ahead of our customers’ needs and seeking continuous improvement. This responds to our main goal: Being our customers’ best business partner.

We add a new competitive advantage by offering more and better solutions to our customers

Through a comprehensive service that includes specialized coating processes for all our screws and fasteners.

In the SNK Group, we have a branch dedicated to the coating of screws and other parts in ZnNi at our facilities in San Andreu de la Barca. We are the first in the industry to have the entire production process in our own facilities.

This means that we are much more agile in terms of quality and delivery times for each order. We are constantly conducting R&D studies in different applications to achieve the best results for our clients.

Therefore, we have developed our own JR 2000 coating.
