P-TREX P is the line of pultruded profiles made of composite material – FRP. They are available in more than 200 sections and in many different materials and colours.
P-TREX G is the line of gratings in composite material – GRFP. Available in different sizes, thicknesses and mesh size.
P-TREX S structures are made by FRP, the best and cost-effective material to face demanding industrial applications and environmental conditions.
P-TREX F fences and gates are the most innovative systems to fence and protect those areas where electrical insulation, amagnetic and chemical resistance are required.
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.

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.
