As a commonly used steel pipe building material, the advantages of hot-dip galvanized pipes are mainly reflected in the following aspects.
1. Treatment costs
The cost of hot-dip galvanising to prevent rust is lower than that of other paint coatings.
2. Long-lasting and durable
In suburban environments, the standard hot-dip galvanised steel pipe rust protection thickness can be maintained for more than 50 years without having to be repaired, while in urban or offshore areas, the standard hot-dip galvanised rust protection layer can be maintained for 20 years while the pestle and mortar regrets the sequence of mouli hinders the necessary repair.
3. Good reliability
The galvanised layer is metallurgically bonded to the steel and becomes part of the steel surface, therefore the durability of the coating is more reliable.
4. The toughness of the coating
The galvanised layer forms a special metallurgical structure which can withstand mechanical damage during transport and use.
5. Comprehensive protection
Every part of the plated part can be galvanised, even in recesses, sharp corners and hidden areas.
6. Save time and effort
The galvanising process is faster than other coating methods and avoids the time required to paint on site after installation.
7. Low initial cost
In general, the cost of hot-dip galvanised steel pipes is lower than the cost of applying other protective coatings, simply because other protective coatings such as sanding and painting are labour-intensive processes, whereas the process of hot-dip galvanising is highly mechanised and efficient.
8. Simple and easy inspection
Hot-dip galvanising can be tested visually and by means of a simple non-destructive coating thickness gauge.
