Seaboard is a high-density polyethylene sheet formulated to meet the specific requirements of marine and other outdoor environments. In addition, special post-production treatment enhances its ability to withstand the effects of salt water, moisture and direct sunlight. Seaboard is manufactured as a continuous extrusion – it is not press laminated. Thus, it is unconditionally guaranteed not to delaminate during the service life of the end product.

Another key advantage of Seaboard is its versatility in fabrication and customisation. It can be easily cut, routed, drilled, and shaped, providing a wide range of options for custom projects. Additionally, it can be easily coloured or printed on, allowing for branding and design customisation.
