Q215B Galvanized square tube
Hot-dip galvanized pipe: Hot-dip galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Complicated physical and chemical reactions occur between the steel pipe matrix and the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. It has the advantages of uniform coating, strong adhesion and long service life.Main uses and industries: widely used in low-pressure fluid delivery and mechanical structures such as fire water supply, gas, air, oil, heating steam, etc.
Q215B Galvanized square tube Features
- Low processing cost: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;
- Durable and durable: the thickness of the zinc layer of the hot-dip galvanized steel pipe meets the standard. In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repairing; in the urban area or offshore areas, the standard hot-dip galvanized anti-rust thickness The layer can be maintained for 20 years without repairing.
- Good reliability: The galvanized layer and the steel are metallurgically bonded and become a part of the steel surface, so the durability of the coating is more reliable.
- Strong toughness of the coating: The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
- Protection: The hot-dip galvanized pipe uses high-pressure air to control the uniformity of the zinc layer on the inner and outer surfaces of the steel pipe, so that every position on the inner and outer surfaces of the steel pipe can be protected.
- Time-saving and labor-saving: the galvanizing process is faster than other coating construction methods, and can reduce the time required for painting on the site after installation.
