Street furniture

Pultruded TRIGLASS®  composite profiles (VTR – GRP – PRFV – CFRP), reinforced with fibreglass and/or carbon, are widely used in public and private street and outdoor furniture.
Their light weight and the excellent mechanical properties of fibreglass make them quick to install even in hard to reach places and/or sites with extreme environmental or weather conditions.
The intrinsic durability of fibreglass profiles significantly reduces maintenance costs which are traditionally high for equivalent structures made in wood and metal. TRIGLASS® profiles are an ideal solution due to their strong resistance to corrosion and weathering and high level of thermal insulation. Some of the many successful applications of TRIGLASS® profiles include in: walkways; handrails; supports for lighting fixtures; waiting benches; handicap ramps; architectural elements and furnishings; poles; fences; pergolas; and bivouacs.

Our product advantages in this sector: Street furniture

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.

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.

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.

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.
