TCBs have recently been installed in 3 newly built wooden wind turbines in Châteauvillain, North-Eastern France.

Mathis SAS is a French company specialising in the design, manufacture and construction of large timber commercial, industrial, residential and leisure buildings; very often incorporating glue-laminated timber and steel frames. Mathis SAS have now entered the wind energy market erecting 3 prototype wooden wind turbines with steel frames bolted with TCBs.

M24 TCB Studs have been deployed to clamp the junction plates with limited access and the use of Standard M24 TCB assemblies as well as TCB Studs radically speed up tower erection with quick and easy installation.

Tension Control Bolts Ltd are glad to be supporting this innovative design. These wooden wind towers with steel frames are aesthetically pleasing, carbon-neutral and each turbine is rated to generate 2.75MW of energy.

As with taller tower designs for Siemens Gamesa, ENERCON and others in the wind energy sector, the use of TCBs avoids welded connections and the potential for associated fatigue and cracks. There is no requirement for maintenance of TCBs and re-torqueing is not required during the design life of the tower.

Tension Control Bolts Ltd have long been pioneers of eco-innovation. Unlike galvanising and other coatings, our patented Greenkote® process is completely eco-friendly.

Greenkote® anti-corrosion protection

Tension Control Bolts Ltd has its own metal coating plant producing an environmentally friendly anti-corrosion coating called Greenkote, which is comparable to galvanising, although it is harder wearing and readily accepts all paint systems. Learn more about Greenkote.
