Hot-dip galvanized I-steel is also called hot-dip galvanized I-steel or hot-dip zinc I-steel. It is to immerse the I-steel after rust removal into the melting zinc liquid about 500℃, so that the surface of the I-steel is attached to the zinc layer, so as to play the purpose of corrosion prevention, suitable for a variety of strong acid, alkali fog and other strong corrosion environment.

Advantages of hot-dip galvanized I-beam steel

1. low treatment costs: the cost of hot dip galvanized rust prevention is lower than the cost of other paint coatings;

2. durable: hot-dip galvanized Angle steel has the characteristics of surface luster, uniform zinc layer, no leakage plating, no drip, strong adhesion, strong corrosion resistance, in the suburban environment, the standard hot-dip galvanized rust prevention thickness can be maintained for more than 50 years without repair; In urban or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair;

3. good reliability: galvanized layer and steel is metallurgical combination, become a part of the steel surface, so the durability of the coating is more reliable;

4. the toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;

5. comprehensive protection: every part of the plating can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected;

6. save time and effort: the galvanizing process is faster than other coating construction methods, and the time required for painting on the site after installation can be avoided.
