Our Objective

Céole's objective is manufacturing towers (masts) for the wind energy industry.

Download the "Visitor’s Guide" to find out how a tower is made.

Wind towers are between 80 and 105 meters tall and weigh between 110 and 250 tons. They are 4.2 m in diameter at the base and 2.4 m at the top. In order to transport them to the installation site, they are manufactured in sections that are up to 36 meters long. Each section weighs between 35 and 80 tons.

We work with thick steel sheets, between 40 mm at the base and 12 mm at the top. Each sheet is bent on a rolling machine, then welded into a ring.  The rings are immediately assembled to form a section. These operations are completed through various welding processes (MIG/MAG welding, flux cored welding...) and with the use of automatic robots.

Once assembled, the section is blasted, then painted. An opening is made on the base section for the access door. The inside of the sections is equipped with terminals to mount the accessories: ladders, cable hangers, platforms, lights, etc.
On each end, the section is equipped with flanges to assemble the sections together on site.

A few figures :
    * Tower height: from 80m to 105m
    * Tower diameter: from 4.2 m (at the base) to 2.4 m (at the top)
    * Tower weight: from 110t to 2500t
    * Power produced by a wind turbine: from 2MW to 3MW
