GRP substructure

GRP – stable, corrosion-free, and durable

 

Icon Profile

 

High load-bearing capacity with low weight

GRP profiles form the stable foundation of every jetty system. They combine high strength with low weight, are significantly lighter than solid wooden beams, and facilitate transport, assembly, and the load on the supports.

Durable, maintenance-free, and economical

Unlike wood, GRP deck substructures are corrosion-free, rot-resistant, and seawater-resistant. Moisture, salt, or biological influences such as fungi and algae do not damage the material. This means no follow-up treatment, no replacement cycles, and significantly lower life cycle costs.

Modular and available as a complete solution

Thanks to their modular design, GRP structures can be flexibly adapted to any jetty system – for coastal areas, inland waters, or floating pontoon systems. In collaboration with experienced partners, complete jetty systems including substructures, GRP decking, and accessories such as GRP railings can be realized – quickly assembled, maintenance-free, and economical.
