Although it is not an excellent thermal insulator, FRP insulates 150–200 times better than steel and 700–800 times better than aluminium. Its thermal conductivity coefficient is very low compared with metals (FRP k = 0.22 W/m°C, STEEL k = 36–54 W/m°C).
Products
- Gratings
Monolithic panels in many formats, quick to install. Wide range of mesh sizes, heights and finishes. Safe: anti-slip surface, electrically insulating, self-extinguishing formulation. Versions for chemically aggressive, ATEX, marine and outdoor environments.
- Pultruded profiles
Profiles in isophthalic resin with high glass fiber content: guaranteed mechanical performance and quality. Available with CE marking via ETA or standard. Numerous open and closed sections ideal for light frameworks as well as structural uses.
- Laminated sheets
FRP laminated sheets are infill and covering panels for walkways, including on concrete. Designed primarily for the protection and safety upgrade of technical surfaces, available on request with anti-slip finish, cutting/shaping to size and various colors.
- Step covers
FRP step covers increase stair safety without invasive work. Made of self-extinguishing polyester resin and glass fiber, they fit onto wood, concrete or steel steps. R13 (DIN 51130) anti-slip surface, yellow anti-trip front edge, available made to measure.
- Mesh
FRP mesh is lightweight, corrosion-resistant and maintenance-free. It is often integrated into airport perimeter security fencing for its radio transparency (does not affect ILS systems) and frangibility properties.
- Corrugated sheet
FRP corrugated sheets offer strength and stability with reduced weight. Ideal for industrial roofing and canopies in aggressive environments, they withstand the elements, reducing installation and maintenance time and costs.
- Fasteners
FRP fasteners (threaded rods, nuts, washers) provide corrosion resistance, electrical insulation and non-magnetic properties. Available in epoxy resin and, on request, also vinylester or isophthalic resin. Threaded rods from 2,200 mm or cut to size; nuts and washers in various diameters.
- Manhole Covers
FRP manhole covers, EN 124, class B125, C250, D400, for inspection chambers. Lightweight, slip-resistant and electrically insulating, they are corrosion-resistant, do not interfere with electromagnetic waves and hold no scrap value for cast-iron thieves. They guarantee strength, light weight and safety.
Systems
- Steps
FRP steps obtained from gratings cut to size with meniscus or quartz anti-slip finishes certified R13 DIN 51130. Used for inclined stairways, access to work platforms, walkways or other industrial structures. Available plain or with step nosing, also made to measure.
- Angular profiles with metal clamps
FRP angular profiles with metal clamps are ideal for creating the perimeter frame of gully covers and trench and manhole covers. They create a stable seating surface thanks to the clamps that anchor into the concrete, preventing slippage and movement over time.
- Frames
FRP frames made with pultruded profiles. They create durable, lightweight perimeter edges for gully covers, trenches and manholes, ensuring a stable seating surface for FRP covers (covered grating). Available with metal clamps or self-anchoring, metal-free, for embedding in the concrete pour.
- Trenches and manholes
FRP trench and manhole covers with covered or double-covered grating: electrically insulating, load-resistant, safe for electrical substations/stations and water treatment plants. Lightweight, easy to install, requiring no grounding or maintenance. Pedestrian and vehicle-rated.
- Parapets
FRP parapets with CE-marked pultruded profiles (Reg. (EU) 305/2011) in isophthalic resin and glass fibers, class E23. Vertical/installation, compliant with UNI EN ISO 14122-3 (means of access to machinery). Also suitable for civil applications (NTC 2018, UNI EN 1991-1-1:2004).
- Ladders
Range of FRP vertical ladders including: service ladders for access and inspection of machinery and plant, ladders suitable for contact with drinking water, and CE-marked ladders for inspection manholes. Available with front or side exit, hatch, safety step and/or rest platform.
- Walkways
FRP walkways with pultruded profiles and gratings, compliant with UNI EN ISO 14122-3 (means of access to machinery). Ideal for walkways, work platforms and pipe crossings. Structure and handrail systems in pultruded profiles, walking surface in FRP grating. Supplied pre-assembled.
- Stairways
FRP inclined stairways compliant with EN ISO 14122, ensuring safe access to plants, walkways and work platforms. Supporting structure, parapets and steps all made of FRP. Single-flight or multi-flight with intermediate landings on single posts made from structural profiles, towers or lattice frames, depending on the specific application, or by support brackets. Stairways for railway embankments.
- Fences
FRP fences for perimeter security. Made with pultruded profiles and grating, or with mesh. They offer electrical insulation, corrosion resistance and non-magnetism, with no maintenance required. Mesh fences are radio transparent and frangible. Can be fitted with barbed-wire toppings and CE-marked gates up to 8 m.
- Gates
Gates made with profiles, grating or mesh in FRP. Lightweight, dielectric and resistant in corrosive environments, they are factory-prefabricated and require reduced maintenance. Available as single- or double-leaf pedestrian gates and double-leaf driveway gates up to 8 m, CE marked, ensuring certified performance and maximum operational safety.
