New partnership, Ucalsa!

We are proud to announce that B2B Marine has recently signed a strategic agreement with Ucalsa from Spain.

Personalised approach

Ucalsa -Utillaje y Calderería SA- was founded in 1986 as an entrepreneurial opportunity in light of the experienced naval industry in the Vigo Estuary. What started out as a small boilermaking workshop for local shipyards has now become, three decades later, the main supplier of structural elements such as doors and hatches for the entire Spanish naval sector, with a modern factory spanning more than 10,000 square metres and more than 60 employees. It can be said that most of the vessels built in Spain today include elements with UCALSA stamp.

Ucalsa specializes in standard and custom products such as exterior doors, special doors, hatches, escape hatches for commercial vessels and jachts, custom alumunium and steel construction, gangways, tanks, special industrial products.

We understand that every vessel is unique, which is why we offer a personalized approach to our services. Our team of experts is available to discuss your specific needs and requirements, and we can work with you to create a custom design that perfectly matches your vessel’s style and functionality.
