- Low processing cost: hot-dip galvanizing costs less than other coatings;
- Durability: In suburban environments, standard hot-dip galvanized rust-proof thickness will last over 50 years without maintenance. In urban or offshore areas, a standard hot-dip galvanized anti-rust coating can last for 20 years without maintenance.
- Good reliability: The galvanized layer is metallurgically combined with the steel to become part of the steel surface, and the durability of the coating is relatively reliable.
- Coating toughness: The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
- Comprehensive protection: All parts of the coating can be galvanized, even in depressions, sharp corners, and hidden places, they can be fully protected;
- Save time and effort: The galvanizing process is faster than other painting construction methods and can avoid the time required for painting on the construction site after installation.
- Low initial cost: Generally speaking, the cost of hot-dip galvanizing is lower than the cost of applying other protective coatings. the reason is simple. Other protective coatings (such as sanding paint) are labor-intensive processes, while the hot-dip galvanizing process is highly mechanized and the construction in the factory is strictly controlled.
- Inspection is easy and convenient: Hot-dip galvanizing can be visually inspected with a simple non-destructive coating thickness gauge.
- Reliability: The specifications of hot-dip galvanizing generally comply with BS EN 1461, and the minimum zinc layer thickness is limited. Therefore, rust protection period and performance are reliable and predictable.
