Due to the strength of the metallurgical bond, along with its ability to withstand very aggressive handling, galvanized coatings continue to be unmatched to date.
The metal is first cleaned, and then the zinc is adhered to the steel using heat as a catalyst. Zinc, unlike other surface coatings, will form a metallurgic bond to the steel, outperforming any other mechanically bonded coating system on the market. Once coated, the zinc will corrode preferentially to the steel using what is called “cathodic” or “galvanic protection”, so that over time, if a scratch appears on the surface, the zinc will react to the elements before the steel will be affected. Bare metal up to one-quarter inch will also be protected by the bonded zinc immediately adjacent to the bare area.
