Finalize technical specifications are in constant contact with Hot Dip Galvanized steel unconsciously from steel construction materials to aesthetic steel objects that are surrounding our daily lives. It is a highly effective & cost efficient method to protect fabricated steel, structural steel, castings, or small parts from metallurgically alloy bond that protects the steel from corrosion.
Depending upon the project requirement treatment of the steel is decided by selecting schedule, coating's service life, and initial and life-cycle costs. 1. Surface Preparation is the most important step in the application of any coating . In most instances where a coating fails before the end of its expected service life, it is due to incorrect or inadequate surface preparation surface that is not perfectly clean. Any failures or inadequacies in surface preparation will be immediately apparent when the steel is withdrawn from contaminants such as dirt, markings, grease and oil from the metal surface. Epoxies, vinyls, asphalt or welding slag must be removed before galvanizing by grit-blasting, sandblasting or other mechanical means.
3. Pickling – Scale and rust normally are removed from the steel surface by pickling slowly from the galvanizing bath and the excess zinc is removed by draining.
The chemical reactions that result in the formation and structure of the galvanized coating continue after the articles are withdrawn from the bath as long as these articles are near the bath temperature. The articles are cooled in either water or ambient air immediately after withdrawal from the bath. Inspection -The two properties of the hot-dip galvanized coating... ... read more »
