Certified industrial capacity, right across the border
We’re based on the same island, in Sint Maarten on the Dutch side, minutes from Marigot and the French-side marinas. That means fast response for French-side yards, resorts and facilities that need certified welding and fabrication.
We bring qualified welders, AWS D1.1 and ASME IX procedures, marine-grade stainless and aluminium fabrication, structural steel and the rigging to lift and set it, without a wait for capacity from far offshore.
Built for Marigot, the marinas and the yacht sector
The French side’s demand centers on the marinas and yacht refit work around Marigot and the lagoon, resort and villa construction, and the building and utility maintenance that supports them.
That’s our lane: marine-grade stainless and aluminium fabrication, structural steel under AWS D1.1, tanks and pressure work under API and ASME, and corrosion protection built for the coastal environment.

From enquiry to a documented handover
A clear path that keeps your project on standard and on schedule.
Scope & enquiry
You send the drawings or scope. We review the code, materials and feasibility, and come back with a quote.
Engineering & WPS
We confirm qualified welding procedures (WPS/PQR), verify mill certificates and material traceability, and plan the lift and weld sequence.
Fabrication & welding
Our in-house shop and field crews cut, fit and weld to AWS D1.1, ASME IX and API, with dimensional and heat-input control.
Delivery, install & inspection
We rig, lift and set the work, run visual inspection and NDT (dye penetrant, ultrasonic), and hand over full documentation.
Built to the standards your facility relies on
Industrial work is only as good as the code behind it.
For your procurement team: welder qualifications (WPS/PQR), certificate copies and safety documentation are available on request for vendor approval.
