Polystone G Checkerplate - Boat Applications

Polystone G Checkerplate: Boat Applications

Dotmar’s Polystone G Checkerplate is designed for floors and walkable surfaces where wet slip resistance is required. Together with its UV stability and aesthetic checkerplate finish, it is an ideal material for marine applications such as boat swim-outs, floors and fishing platforms.

For the wet barefoot inclining slip-resistance (AS4586), Polystone G Checkerplate maintains grip up to 23 degrees incline.

There are several types of boats and applications that could benefit from a HDPE Checkerplate transom. A few examples are as follows.

Ski/ Wakeboard Boats

Used as a swim/mounting platform for riders (wakeboarders/skiers) to dismount into the water for recreational activities.

Fishing/ Sea Exploration Boats

Used as a platform for fisherman to bring in their catches or for divers to dismount into the water. Ladders can also be attached for users to get back into the boat.

Transfer Boats

Checkerplate materials can be used to create platforms when transferring cruise ship users to their destinations such as remote islands via smaller boats.

Benefits of using HDPE Checkerplate over existing materials such as fibreglass, aluminium or wood.

	HDPE Checkerplate vs Alternative Materials for Nautical Transom Use
Material	HDPE	Fibreglass (Composite)	Wood	Aluminium
Water Resistance	Impermeable to water, does not absorb moisture or swell	Low water absorption, depends on finish quality	Water resistance improves with sealing or pressure treatment, but vulnerable over time	Does not absorb water, highly resistant but may corrode over time
Water Absorption Rate	0.01% (Virtually none)	0.1-0.3%	8-25%	0% (none)
Chemical Resistance (Overall)	Excellent resistance to most chemicals	Resin types determine performance, can degrade with solvents	Not suitable for strong chemicals, regardless of treatment	Susceptible to corrison from acids and salts
Chemical Resistance (Salt)	Excellent	Excellent	Fair to Poor	Fair to Good
UV Degradation	Prolonged exposure can cause UV degradation - can be UV stabilised	Can perform well depending on the coating	No affect from UV	Sealing can improve resistance, but requires maintenance over time
Corrosion	Fully corrosion resistant: does not rust or degrade in contact with water, salt, acids, or bases	Excellent resistance to corrosion, can degrade over time with harsh chemicals	Susceptible to long-term moisture damage	Vulnerable to galvanic, pitting, and saltwater corrosion unless coated or anodised
Density (Weight)	941-965kg/m3	2000kg/m3	1500kg/m3	2699-2810kg/m3
Impact Resistance	Excellent impact resistance: Flexible and tough, does not crack or shatter easily	Strong and stiff, but can be brittle under sudden impact	Good impact resistance, depending on wood treatment	Moderate impact resistance, may dent or deform rather than crack
