The company, which delivers concrete-steel hybrid towers to leading wind-turbine suppliers, including Alstom, GE, Nordex, Senvion and Vestas, is opening the plant to reduce road transport costs. It will be open in the summer.
A large proportion of the company's products are shipped to projects in Germany. The hybrid towers are of a modular-design with a hub height of up to 150 metrws.
Each hybrid tower comprises a concrete bottom part with one or more tubular steel sections atop.
The modular system enables creating concrete towers of different height and geometry to suit turbine power rating and rotor size, hub-height and IEC wind class specific demands.
The concrete part consists of multiple steel-reinforced rings of 3.8 metres in height and 0.3-metre wall thickness stapled using a precision dry-joint method. The largest bottom rings come in two or more segments for easier transport, whereby transporting one complete tower typically requires many road and/or vessel movements.
