GRP Structures | P-TREX S
Logo PTrex

P-TREX S structures are made by GRP, the best and cost effective material to face demanding industrial applications and environmental conditions. Fiberglass walkways and parapets, stairs and bridges, are developed on the basis of the needs of the context and starting from a feasibility study of the project.

Pre-assembly in-house

Our fiberglass solutions are pre-assembled in house, according to the synergy between the design and production office and supplied to the shipyard together with the technical details and assembly sheets, saving time and costs in on-site operations. Thanks to more agile and faster installation activities, the result is an efficient, tidy and clean construction site.

There’s a GRP solution for every problem.
