PAINTS FOR IRON SURFACES

The low carbon steel, which is commonly called iron, used in the construction of carpentry and in all steel structures such as bridges, construction cranes, industrial vehicles, railway carriages, building blocks, etc…, can rust, that is to go to the phenomenon of corrosion, which is a spontaneous and irreversible process triggered by the chemical-physical interaction with the environment.

Rust is formed by the action of oxygen in the air on the surface of the iron, with the contribution of water in the form of atmospheric or rain humidity and sometimes also due to the intervention of atmospheric sulfur dioxide. The rust, once formed, detaches from the surface of the metal and crumbles, leaving the underlying part of the steel exposed to new aggressions.

This phenomenon leads to the loss of the low carbon content steel resistance capabilities, until its destruction, in any case to reach the technological decay with the reduction of the functional efficiency, it is sufficient that the corrosion hits few specific points. To prevent corrosion or in any case to slow down its formation, it is advisable to protect the ferrous supports so as to isolate them from the corrosive agents of the external environment, applying the anticorrosive paints that create a barrier.
