Railway

Pultruded TRIGLASS® composite profiles ( GRP), reinforced with fibreglass and/or carbon, are widely used in the rail sector (trains, trams and underground transport). They are used both within wagons as well as in other infrastructure in these systems.
Composite materials and pultrusion allow manufactured products with complex shapes that have excellent mechanical properties and significant resistance to corrosion (whether caused by chemicals or stray current).
In addition, Top Glass has developed specific formulas for over twenty years which give profiles high self-extinguishing characteristics and limited toxicity of smoke in the presence of fire. This enables their use also within railway passenger cars and tunnels.
The standard cable trays from our catalogue, as well as customized versions, have long been valued by small scale installers. They have also been used by larger clients in important large scale infrastructure projects such as the English Channel Tunnel.
The lightness of composites and their high resistance allows use in above ground electrical ducting (such as the ARCO EINS and ARCO ZWEI systems). They offer considerable savings in time and transportation as well as maintenance.
Some applications include: pedestrian emergency walkways in the event of breakdowns or fire; emergency handrails; light supports; waiting benches; disabled access ramps to modernise stations; and architectural and acoustic elements. These are just a few examples of the many successful uses of TRIGLASS® profiles.

Our product advantages in this sector: Railway

Composites have an excellent ability to withstand environmental agents and highly aggressive chemicals.

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.

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.

Fibreglass profiles are transparent to electromagnetic waves and do not generate interference at a radio frequency level.

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.
