ASTM Galvanized Steel Round Tubing

Galvanization provides a protective zinc coating that prevents premature rust and corrosion on your tubing. With this protective coating, galvanized round tubing will not only last longer but will also require less maintenance.

Hot-dip galvanized round 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 steels 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.

Galvanized Steel round pipe 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.

Benefits of Using Galvanized Pipes and Tubes

• Galvanized pipes and tubes are very durable and have a long life. They have better impact resistance and anti-wear properties than ordinary steel pipes because zinc has a greater hardness value than steel.
• They have a high level of abrasion resistance and can withstand harsh weather conditions such as wind and rain.
• They are easy to handle during transportation and application and can be implemented in structures easily.
• They are resistant to corrosion and road salts.
• They do not need additional coats of paint.
• They are easy to examine for damage. They can be inspected with the naked eye.
• The materials in the inner cavity of the pipes and tubes have a high level of protection because zinc is very hard to penetrate.
• Owing to their durability and hardiness, they do not need a high level of maintenance or repair.
