At Zeman Manufacturing, we form precision tubing for the marine industry—commercial vessels, pleasure craft, racing boats, and the dock systems that serve them. Salt spray, vibration, and constant loading demand corrosion-resistant materials and leak-free joints; our tubes deliver both, helping boatbuilders and dock installers keep crews and cargo moving safely.
Using advanced bending and tube-laser technology, we conform to your drawings and tolerances, supplying stainless steel, aluminum, and carbon-steel tubing ready for immediate fit-up on hulls, decks, ramps, and trailers.
Dock-Lift & Dock-System Tubes
Heavy-wall tubing supports lift arms, gangways, and floating or moored dock frames, combining strength with smooth finishes that resist corrosion and abrasion.
Exhaust & Pump Components
Precision-bent exhaust tubes and pump manifolds handle hot gases and seawater circulation, with clean weld preps and exact bends that minimize back-pressure and flow losses.
Frames & Rail Mounts
Tubular frames, grab rails, and rail mounts provide rigid, lightweight structure for topsides, consoles, and safety railings, fabricated for consistent geometry and ease of assembly.
Grab Bars, Handrails & Ladders
Ergonomic, polished tubing creates hand-safe bars and stern- or dive-ladders that withstand repeated impact, UV, and saltwater exposure.
Trailer & Ramp Assemblies
Structural tubes form bunks, winch posts, and guide rails for boat trailers and loading ramps, delivering the stiffness and durability required for on-road transport.

Marine applications leave no margin for corrosion or mis-alignment. Zeman couples advanced bending, laser cutting, and end-forming with ISO 9001:2015 and ISO 13485:2016 certified quality systems to ensure every tube meets tight tolerances and resists the harsh marine environment. From shipboard exhausts to dockside frames, we keep your project moored exactly where it should be—on spec, on time, and built to last.
