National standard flange galvanizing process

The advantages of the national standard flange after hot-dip galvanizing: a cost paper: the cost of hot-dip galvanizing rust is lower than the cost of other paint coatings; two durable: in the suburban environment, the standard hot-dip galvanizing rust The thickness can be maintained for more than 50 years without repairing; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repairing; three reliability is good: metallurgical bonding between galvanized layer and steel. It becomes part of the steel surface, so the durability of the coating is more reliable; the toughness of the four coatings is strong: the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use; Protection: Each part of the plated parts can be coated with zinc, which can be fully protected even in depressions, sharp corners and hidden places; six provinces save time: the galvanizing process is faster than other coating construction methods, and It can avoid the time required to brush on the construction site after installation.
