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.

    The table illustrates the mechanical characteristics of the fiberglass profiles, for the determination of which reference is made to the standards EN 13706-2, EN ISO 527-4, EN ISO 14125 and EN ISO 13130. The values shown in the table are the result of tests made on standard profiles with resins and different thicknesses. For the structural calculation always refer to the values shown in the specific technical data sheet of the product to be used.


    P-TREX S Structures are etremely performing in aggressive environments, even when in contact with liquids or vapours.


    P-TREX F and P-TREX S are widely used in the electricity and telecommunications industries for fencing off and protecting where electrical, thermal and magnetic insulation is required.


    P-TREX S structures in composite material are especially suitable to be used in harsh environments, such as those of the manufacturing or food industry.


    P-TREX F and P-TREX S are widely used in the railway sector.


    P-TREX product lines are designed to ensure the highest possible standards of safety and protection in all airport and port facilities.


    P-TREX S structures don’t fear corrosion or oxidation even in case of steady presence of water. Since they are resistant to adverse weather conditions and don’t alter over time, they don’t need maintenance and are the ideal solution to the problems encountered in water purification plants.


    P-TREX pultruded profiles, structures and fences are guaranteed by FIBRE NETexperience and know-how
