1. Low processing cost: the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings; 2. Durable: hot-dip galvanized angle steel has a glossy surface, a uniform zinc layer, no leakage, no dripping, and With strong strength and strong corrosion resistance, in suburban environments, the standard hot-dip galvanized rust-proof thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized rust-proof layer can be maintained 20 years without repairs;

3. Good reliability: The galvanized layer and the steel are metallurgically bonded and become part of the steel surface, so the durability of the coating is relatively reliable;

4. The coating has strong toughness: The galvanized layer 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, even in depressions, sharp corners and hidden places, they can be fully protected;

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