Case Study
How a boat cover support pole was made to resist seawater, protect the deck and float
A US marine brand asked us to make a cover support pole that props up the boat cover so rain and snow run off instead of pooling. The product design and the market are the client's; we handle structure, materials, finishing, inspection and shipping.
First, solve
seawater corrosion
Then, snow load
and deck scratches
Finally, add
Floats if dropped

Our role
Structure, materials, finishing, base, inspection and shipping
01 What the pole has to solve
Once a boat is covered, the middle sags and collects water; in winter, snow piles onto the cover. The pole has to hold the cover up so rain and snow slide off. A boat uses 1 to 10 poles depending on its size, and lengths and section counts change with the boat.
02 What makes it hard
Seawater corrodes
Boats sit by the sea for months, so the pole has to withstand seawater and salt air.
Snow presses down
Under load, the pole must not punch through its end cap and damage the deck.
Moved often, never scratching
The pole is moved often and used for years, so its base must leave no marks on the deck.
It may fall overboard
Working on a boat, a pole will sometimes go in the water, so it has to float.
03 How we built it, step by step
Start with seawater
A marine-grade anti-corrosion finish solves corrosion first.
Base material
Switched to soft, non-marking materials: no punch-through under load, no scratches when moved.
Buoyant structure
Buoyancy comes from the internal structure itself, with no add-on float, so it floats whatever the section count.
A full size range
A full range of lengths and section counts to fit different boat sizes.
04 How it is used on board
Three steps: extend to the height you need, lock it, and lift the cover so rain and snow run off.
05 How it is tested
•Salt spray test: ASTM B117 / ISO 9227, hours set by finish and client requirements
•Axial load test: the weight it carries along the shaft when locked
•Pull test: the force it withstands along the shaft when locked
06 What we delivered
Protection
A marine-grade anti-corrosion finish for boats moored by the sea.
Details
A non-marking base and flotation, built into every pole.
