Marine fabrication
Marine fabrication, from watertight doors to one-off hardware.
Some things you can't buy off the shelf: a watertight door for a 50-year-old research vessel, a davit mount for an odd transom, a hatch that has to pass inspection. That's our shop's specialty — custom marine fabrication in aluminum, steel, and stainless, built to spec and fitted right.
Fabrication work we handle
- Watertight doors and hatches — fabrication, repair, certification support
- Custom aluminum structures — T-tops, platforms, brackets
- Stainless rails, mounts, and deck hardware
- Tanks — fuel, water, and holding
- Equipment foundations and machinery mounts
