LED dome GEP Paris_

A giant carbon fibre dome incorporating thousands of LED lights installed on the inside of an existing antique stone dome. The lightweight carbon structure carries its own weight and thus doesn’t stress the existing structure. Gallery Éléphant Paname in Paris.

GRP Roof Structure - Centerparcs Aquamundo_

After many years of service, the wooden support structure of the roof of the Centerparks Aquamundo Tropical swimming pool was no longer fit for purpose. The swimming pool environment is a very chemically aggressive environment. Even the most corrosion resistant steel types cannot cope with the temperature, humidity and chlorine fumes. GRP has very good corrosion resistance qualities and together with Buursema, Dantuma en Wegkamp and BIJL Profielen, Solico designed one the largest single span GRP roof structures in the world to support the roof loads. 

Pedestrian and bicycle bridges_

In cooperation with W.B. BIJL B.V. Solico has developed a flexible pedestrian bridge concept assembled from pultrusion profiles. Multiple bridges have been produced and installed.

The fatigue resistance of composites is much better than that of metals. Of course fatigue failure also occurs in GRP and CFRP and has to be analysed in detail.


Slender constructions and seamless façades are examples of aesthetics driven design. These type of structures are impossible to construct with traditional materials.


Typical GRP lambda values are 1, compared to 50 for steel and 237 for aluminium, which results in excellent insulation properties.


The specific weight of composites varies between 1.5 and 2.0 compared to 2.7 to 7.8 for aluminium and steel.

High strength

In general, fiber reinforced plastics outperform metals (e.g. steel and aluminium) in strength.

Chemical/corrosion resistance

Composite materials are resistant to a lot of chemical products such as acids, hydroxides, crude oil, etc. Corrosion resistance against salt and seawater is excellent.

Cost effectiveness

Though composite materials themselves are slightly more expensive than metals, combining properties such as insulation and weight savings often results in a cost effective product.

Freedom of geometry

Double curved shapes are easily produced in composite materials at almost no extra cost. For production of limited series the relatively low moulding costs are an additional benefit.


The non-magnetic properties of glassfiber reinforced composites are a major advantage especially in sonar and radar applications.

Limited thermal expansion

Thermal expansion of composite materials can be tuned. Depending on the fiber used it can vary between 0 and 30 where steel has an alpha of 12.

Integration of functions

By combining functions such as strength and insulation in one product, a composite solution is often more cost effective than the sum of traditional solutions.

Low maintenance

Steel structures typically require periodic maintenance such as conservation and paint systems to prevent corrosion. Composites are not susceptible to corrosion resulting in lower Life-cycle costs.

Sonar/Radar Transparency

Composites are very well known for their transparency to radar and low damping properties.

High stiffness to weight ratio

The stiffness to weight ratio of a high modulus carbon fiber construction is typically 5 times higher than steel or aluminium.
