Spray Galvanizing

Thermal Spray Zinc Coating

Atomized particles of molten Zinc are projected on to a Grit or Sand blasted steel surface from a special flame or arc pistol fed with Zinc wire. The process is often applied to structural components too large to be dipped in a galvanizing bath, and to structures which are likely to distort during hot dip galvanizing. Zinc coatings for iron and steel provide excellent corrosion resistance in most atmospheres, and in contact with many natural and synthetic substances. Zinc coatings are widely used to protect finished products ranging from structural steelwork for Chemical, Fertilizer, Refinery, Cement, Power plant, buildings, bridges, Pipe lines, etc.

The electrochemical relationship between zinc and steel enables zinc coatings also to protect steel at cut edges and at breaks in the coating by a sacrificial action.
