As a commonly used steel pipe building material, the advantages of hot-dip galvanized pipe are mainly reflected in the following aspects:
1. Low processing costs
Hot-dip galvanizing is less expensive than other paint coatings.
2. Durable
In suburban environments, the anti-rust thickness of standard hot-dip galvanized steel pipes can be maintained for more than 50 years without repair; in urban or offshore areas, the standard anti-rust layer of hot-dip galvanized steel pipes can be maintained for 20 years without repair.
3. Good reliability
The galvanized layer is metallurgically bonded to the steel and becomes part of the steel surface, so the durability of the coating is more reliable.
4. The coating has strong toughness
The zinc coating forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
5. Comprehensive protection
Every part of the plated part can be coated with zinc, so even recesses, sharp corners and hidden places can be fully protected.
6. Save time and effort
The galvanizing process is faster than other coating application methods and eliminates the time required to paint on site after installation.
7. Low initial cost
In general, the cost of hot-dip galvanizing steel pipes is lower than applying other protective coatings. The reason is simple. Other protective coatings such as sanding and painting are labor-intensive processes. On the contrary, the hot-dip galvanizing process is highly mechanized and more efficient.
8. Inspection is simple and convenient
The hot-dip galvanized layer can be tested visually and with a simple non-destructive coating thickness gauge, making inspection easy.
