Most of the steel in a wind turbine is the tower. About 90% of all wind turbine towers are tubular steel towers. They are called tapered tubular towers because they gradually narrow towards the top. To construct a tower, fan-shaped plate segments are cut from rectangular parent steel plates and roll-formed and welded into cone sections. A

Inspection of coating on steel structures

Wind turbines, bridges and other structures of steel are exposed to wind and weather that make them corrode and reduce their service life. Paint and galvanization are used to protect steel surfaces against corrosion attacks, but if these coatings are not applied correctly, the protection is not effective.
