Most large wind turbines are equipped with tubular steel towers which must be able to perform in some of the harshest working environments in the world over long periods of time. Due to their exposed locations they are subjected to a multitude of stresses.

Steel Towers - an Economic and Proven Overall Solution

Among the advantages of the choice of steel towers are the speed of erection, the economical side and the reliability of the designs. Owner, engineer and contractor need a proven complete solution for a fast, efficient and durable erection of their wind farm.

To meet all these requirements, Sika has formulated corrosion protection coating systems for steel tower sections and optimized construction grouts to facilitate the erection of the tower.
Our corrosion protection systems allow our customers to protect their steel in the full range of defined corrosive categories that protect both the interior and the exterior of onshore steel towers.
Our construction grouts permit our customers to erect their turbines in a fast and safe way, optimizing the time need of cranes and auxiliary equipment.

Corrosion Protection

SikaCor® and Sika® Permacor® high quality corrosion protection systems for - interior and - exterior surfaces of steel towers are based on high-strength, modern binder resins which enable very low solvent content formulations.

Primers with active pigments and thick-layer intermediate coatings ensure long-lasting corrosion protection, the top coats based on polyurethane technology meet the highest requirements for weather resistance and colour stability. In several decades of service, our corrosion protection systems have protected over 10,000 wind turbines.

Grouting to fill Voids

Sika grouting technologies are cementitious, resin or polyurethane binders. Engineering grouts are designed to completely fill voids and transfer load. SikaGrout® and Sikadur® are ideal for the filling of - vertical or horizontal joints; - for levelling of interacting concrete surfaces and filling very small holes - Sika cable grouts fill small crevices around post tensioned wires to protect the steel from corrosion.
