Pultruded TRIGLASS® composite profiles (VTR – GRP – PRFV – CFRP), reinforced with fibreglass and/or carbon, are widely used in the transport industry due to their light weight (making them energy and consumption saving), excellent mechanical characteristics and durability.
Top Glass has the capacity to make custom profiles, including large custom profiles, and those with complex shapes. This, combined with the availability of specific versions and reinforcements, allows TRIGLASS® profiles to be used in a variety of applications including:
– profiles for highly insulated refrigeration lorries (can be used in their structure and closure panels)
– nautical, ground, and automotive antennas
– overhead luggage racks, ceilings and ventilation ducts for buses and rail wagons and
– covering panels for both the inside and outside of transportation means
What are the possibilities?
- Luggage racks
- Ventilation and heating ducts
- Insulating frames
- Rail fixtures
- Roof panels
- Structural panels
- Structures for compartment divisions in boat hulls
- Nautical floor support structures
- Ceiling profiles
- Profiles for railway cars
- Internal reinforcement for tarpaulins
- Rack shelves

Composites have an excellent ability to withstand environmental agents and highly aggressive chemicals.
Composite materials can be worked using conventional woodworking machines that have the ability to use diamond tools and/or those specified for fibreglass. You can also perform other operations on them such as connections with bolts, screws and rivets as well as gluing and painting.
A wide choice of resins allows the design of composites with strong resistance to atmospheric agents and weathering. Rain, particulate abrasion, UV radiation and temperature boundary conditions are easily controlled by means of different formulation strategies and/or surface protection.
The amorphous structure of composites stands up very well in large temperature fluctuations without presenting significant or permanent sectional deformation. The response of the material to applied loads is practically always in terms of elasticity. It has low creep and is consequently very stable.
Fibreglass-based materials and thermosetting polymers have high dielectric capacity. Both components are inherently excellent electrical insulators. This characteristic is related to their optimal response to arc discharge, tracking, and surface and density resistivity.
The specific gravity of pultruded material is about 1.8 g/cm ³. It is much lighter than steel (7.85 g/cm ³) and aluminium (2.7 g/cm ³). Its high performance relative to weight allows the design of structures with low energy impact. Its lightness is also an advantage in relation to transport and logistics as well as low response to inertial forces, relevant to building structures in seismic areas.
Polymeric materials have insulating characteristics, resistance to weathering and chemicals and pigmentation possibilities (en masse) that allow their installation and use with almost zero maintenance.
The mechanical properties of composites are generally high and can be customized to take advantage of the anisotropy of reinforcement structure. The strongest enhancements have been in the longitudinal direction, which coincides with the direction of the pultrusion process. Resistances in that direction are now comparable to those of steel. In the case of unidirectional composites, longitudinal strength values can be triple those of steel. In contrast to traditional metal materials, pultruded profiles reflect behaviour that is elastic-brittle until breaking.
Composites have an excellent ability to withstand environmental agents and highly aggressive chemicals. A wide range of resins makes it possible to design materials adapt for contact with diverse chemicals, especially acids, alkaline substances and solvents.
