Pultruded TRIGLASS® composite profiles (VTR – GRP – PRFV – CFRP), reinforced with fibreglass and/or carbon, are widely used in industry due to their lightness, excellent mechanical characteristics and durability.
The inherent features and versatility of TRIGLASS® profiles make them an ideal solution for designers and technicians who recognize the unique advantages of composite materials over traditional ones.
Top Glass has the capacity to make custom profiles including large custom profiles and those with complex shapes. This, combined with the ability to make specific versions and stratifications, allows TRIGLASS® profiles to be used in a variety of applications.
Their excellent mechanical properties allow use as general reinforcements in hammer and other tool handles and with marble surfaces that are often fragile and difficult to transport. They are also used in making umbrella frames, industrial brushes, and quick roll-up sectional and fire doors.
Their excellent thermal insulation capacity, dimensional stability (even in presence of large temperature changes) and resistance to chemicals make pultruded profiles widely used in: industrial systems such as mills and sieves; food machinery for making pasta; industrial washing equipment in the textile industry; and glass production as spacers for autoclave treatments.
Due to their unique radar transparency and high mechanical resistance, Top Glass pultruded profiles are essential for the construction of metal detector machines in the safety sector.
Suction hoods in chemical systems, panelling, design elements and rollers for automatic packing systems with shrink wrap are other examples of the versatile potential uses for pultruded TRIGLASS® profiles in industry.

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.
Predicting the durability of composite materials is a topic Top Glass has studied for a long time. Our findings suggest optimal behaviour in outside conditions and bad weather. Of course, special conditions should be assessed to select the raw materials best suited to maximizing long-term mechanical and aesthetic features.
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.
Fibreglass composite materials have a very low thermal conductivity coefficient, around 0.3 W/mK. This feature offers significant advantages in situations where energy loss might have a negative impact, both economically and functionally. This is particularly the case in the fields of construction and thermal insulation.
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.
