Corrosion Corrosion in steel is an electrochemical process that oxidises the iron in the steel. Oxidation occurs as a result of the chemical reaction between steel and oxygen, where steel is consumed converting iron to corrosion products. Paints are barrier coatings that, when applied and used properly, give sufficient corrosion protection to steel for many common applications.
Galvanisation The main mechanism by which galvanised coatings protect steel is by providing an impervious barrier that does not allow moisture to contact the steel and therefore prevents corrosion. The metallic zinc coating has excellent adhesion, abrasion, and corrosion resistance. Galvanised coatings will not degrade as with other barrier coatings such as paint. The protection offered by a galvanised coating is proportional to its thickness and to the corrosion rate.
The second shielding mechanism is zinc's ability to protect steel galvanically. When zinc and steel are in contact in the presence of an electrolyte, a current will flow from the steel to the zinc, so that the zinc becomes an anodic electron-producing region while the steel is cathodic and consumes electrons, preventing it from combining with oxygen and forming rust.
When base steel is exposed, such as at a cut edge or scratch, the steel is cathodically protected by the sacrificial corrosion of the zinc coating as zinc is more electronegative than steel. Therefore a zinc coating will not be undercut by rusting steel because the steel adjacent to the zinc coating cannot corrode. Any exposure of the underlying steel, due to severe coating damage or a cut edge, will not result in corrosion of the steel until the adjacent zinc has been consumed.
Maintenance The Vectaire FRAB range should be regularly cleaned by wiping with a damp cloth. Do not use abrasive or solvent cleaners.
