A regional contractor for St. Kitts and Nevis
We’re a certified Caribbean contractor that mobilizes crews and equipment to St. Kitts and Nevis for work that has to meet standard. From Basseterre’s port to construction and energy projects, specialized welding and fabrication is often sourced regionally.
We bring qualified welders, AWS D1.1 and ASME IX procedures, structural steel fabrication and the rigging to lift and set it, so a project on either island gets certified capacity without waiting for it locally.
Built for the ports, construction and energy
Industrial demand across St. Kitts and Nevis centers on the port at Basseterre, an active construction and tourism-infrastructure pipeline, and energy projects including the geothermal development on Nevis.
That work runs on structural steel, welding, tanks and mechanical maintenance. We deliver it to code: structural steel under AWS D1.1, pressure equipment and piping under ASME, and storage tanks under API 650/653.

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.

Regional coverage across the Caribbean →Working with Tasweldermechanics in St. Kitts & Nevis
No. We’re based in Sint Maarten and mobilize crews and equipment to St. Kitts and Nevis for each project. That regional model brings certified, specialized capacity where a local shop can’t.
Certified welding, structural steel and metal fabrication, tank fabrication and repair (API 650/653), crane and heavy-lift services, plant and mechanical maintenance, and qualified personnel supply.
Yes. We fabricate and install structural steel, handle pipe and pressure welding, and provide heavy lift and mechanical crews for port, construction and energy work, including geothermal-related fabrication.
Our procedures follow AWS D1.1 and ASME Section IX, with qualified WPS/PQR. Certificate copies and safety documentation are available for vendor approval.
