SHOP BY PERFORMANCE
Salt water is the loudest test. It is not the only one.
Coastal boards are rated marine grade, but the same formula also decides how they handle load, span, upkeep, and profile. Here is the rest of it.
Marine-Grade Performance
Engineered for constant water contact — salt spray, freeze-thaw, and full submersion.
No Rot / No Wood Fiber
No organic filler means nothing for rot, mold, or insects to feed on.
Low-Maintenance Decking
No sanding, no staining, no sealing. Soap and water is the whole routine.
Heavy-Duty Plastic Lumber
For the loads and traffic that chew through conventional decking.
Profile & Size Flexibility
A full range of profiles and lengths — a material system, not a single board.
24″ On-Center Span
A structural advantage that can simplify framing when the application supports it.
