Once you Process of hot-dip galvanized | Haihao Pipe Fitting FactoryHot dip galvanizing is the process of galvanizing coated materials such as steel, iron, or aluminum to prevent them from corroding due to possible exposure to harsh conditions. Hot dip galvanizing is to dip the workpiece in a solution of zinc. This causes a metallurgical reaction that combines the outer layers of both metals, creating a uniform and highly resistant surface.
Process for Galvanized Coating Repair
A systematic approach is required when repairing hot-dip galvanized coatings on structural steel. A procedure should ensure that all work carried out when repairing hot-dip galvanized coatings on structural steel adheres to this systematic approach. Properly stipulated procedures, inspection, testing and resources are required for carrying out galvanizing repairs, which can be deemed as Minor Repair and Major Repair.
