GRP Cooling Towers_

Solico engineered and delivered the construction as well as the workshop drawings for several GRP cooling towers all over the world e.g. in Germany, The Netherlands, Spain, Australia, Kazakhstan, Belgium, etc... The choice of composite material for producing these towers is straightforward as composite material provides chemical and corrosion resistance and requires minimal maintenance over time. 

GRP Roof Structure - Centerparcs Aquamundo_

After many years of service, the wooden support structure of the roof of the Centerparcs Aquamundo Tropical swimming pool was no longer fit for purpose. The swimming pool environment is chemically aggressive. 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 of the largest single span GRP roof structures in the world to support the roof loads. 

Efteling theme park, Netherlands_

Solico made the structural design of various objects used in entertainment parks or in public space as artwork. Examples include "The Flying Dutchman" and "Python" carts, the "Sprookjesboom" support structure and the "Wonderwachter" lamps.

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.


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


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.

Sonar/Radar Transparency

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

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.


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

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.

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.


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

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.


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

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.

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.
