The fight against corrosion requires a strict strategy

Steel structures face corrosive conditions that are defined by the environment where it is placed in. However, the use of the facility determines which maintenance strategy is applicable and feasible.

A protective coating system should offer anticorrosive power whether by using active anticorrosive pigments such as zinc, or by using the barrier principle, aiming to prevent penetration of water or water vapour through the coating film. It also should adhere firm to the substrate but also cohesion between paint layers must be appropriate. Also, the system must be resistant to corrosive agents and to the expected mechanical impact.

Various factors can determine the choice of a system and in order to come tot a decision, it must be clear which one has the highest priority. Of course the technical service requirements related with the nature of the project will mainly determine the type of binder suitable.
