Storage tanks and silos for Spiromatic_

Solico has the necessary in house skills, experience and software package to provide dedicated designs of storage tanks and silo’s according to EN 13121, DIBt, ASCE etc...

GRP sea outfall couplings_

GRP couplings are used to assemble HDPE pipe sections into an 11 km long sea outfall pipeline. The pipeline consists of several sections of HDPE pipe with an outer diameter of 1600 mm and a wall thickness of 61 mm. Each pipe section has a length of approximately 550 meter. Solico developed the concept of the GRP couplings to withstand the forces during installation and to provide maintenance and leak free couplings between the HDPE pipe sections during its design life. The result is a coupling that connects the pipe sections without using any metal parts.

Greenprop Composite Propeller_

Solico engineered and delivered a high tech composite propeller for project “Greenprop”. This unique propeller postpones the phenomenon of cavitation due to its higher flexibility and torsion-bending coupling. The bonding of the composite propeller to the metal hub was particularly challenging because of the high cycle fatigue loads. The propeller was successfully tested in late 2017. The potential of this propeller lies in higher speeds and lower noise emission levels.

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

Sonar/Radar Transparency

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


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.

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.


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


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

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.

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.

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.

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.
