Materials

Standard gauge boards are produced as encapsulated Glass Reinforced Plastic prints. They are 4 mm thick, drilled, and are normally supplied with stainless steel screws. GRP is tried and tested. It gives a tough and robust product, and is suitable for long-term immersion in water.

Fixings

PVC backing boards are available in either 1.5 or 3.0 metre sections [as a stock item]. These are intended to be a support, not a post system. Timber or galvanised steel posts, together with suitable fixings, can be quoted on request.
