Hot dip galvanized I-beam
Hot dip galvanized I-beam is also called hot-dip galvanized I-beam or hot-dip galvanized I-beam. It is to immerse the derusted I-beam into the molten zinc at about 500 ℃, so that the zinc layer is attached to the surface of the I-beam, so as to achieve the purpose of anti-corrosion. It is suitable for all kinds of strong corrosive environments such as strong acid and alkali fog.
1. Low treatment cost: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;
2. Durable: the hot-dip galvanized angle steel has the characteristics of surface gloss, uniform zinc layer, no missing plating, no dripping, strong adhesion and strong corrosion resistance. In the suburban environment, the standard hot-dip galvanized antirust thickness can be maintained for more than 50 years without repair; In urban or offshore areas, the standard hot-dip galvanized antirust coating can be maintained for 20 years without repair;
3. Good reliability: the zinc coating and steel are metallurgically combined and become a part of the steel surface, so the durability of the coating is more reliable;
4. Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;
5. Comprehensive protection: every part of the plated parts can be plated with zinc, and can be fully protected even in depressions, sharp corners and hidden places;
6. Time saving and labor saving: the galvanizing process is faster than other coating construction methods, and the time required for painting on the site after installation can be avoided.
