Send the request immediately.
Advantages And Performance Of Hot Galvanized Structural Steel Pipe
1. The processing cost of hot-dip galvanized steel structural pipes is low: the rust prevention cost of hot-dip galvanizing is lower than other coatings. Generally speaking, the cost of hot-dip galvanizing is lower than that of coating other protective coatings, for a simple reason. Other protective coatings, such as polishing and painting, are labor-intensive processes, while hot-dip galvanizing is a highly mechanized and strictly controlled factory construction process.
2. Hot dip galvanized structural pipes are durable: In suburban environments, the standard hot-dip galvanized anti rust thickness can be maintained for more than 50 years without maintenance; In urban or coastal areas, standard hot-dip galvanized anti rust coatings can be maintained for 20 years without the need for maintenance.
3. Hot dip galvanized steel structural pipes have good reliability: the bonding between the galvanized layer and the steel is metallurgical, making zinc a part of the steel surface, thus ensuring good durability of the coating.
4. The coating toughness of galvanized steel structural pipes is strong: the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
5. Comprehensive protection: Each part of the plated part can be galvanized, even in concave, sharp, and concealed areas, it can be fully protected.
6. Time and effort saving: Galvanizing process is faster than other coating methods, which can avoid the time required for painting on the construction site after installation.
7. Easy inspection: The hot-dip galvanized layer can be visually inspected and tested using a simple non-destructive coating thickness gauge.
8. Reliability: The specifications of hot-dip galvanizing usually comply with BS EN ISO 1461, which limits its minimum zinc layer thickness, so its rust prevention period and performance are reliable and predictable.

Making Process Of Structural Galvanized Steel Pipe
Yuantai Derun makes structural galvanised steel pipes using two processes. One is hot-dip galvanizing, the other is pre-galvanizing and forming welding. Here are the main steps of the hot-dip galvanizing process:
1. Treatment of the surface: Clean the metal to remove dirt, oil stains and rust.
2. Acid washing: Acid wash the metal to remove any remaining oxides or contaminants.
3. Flux: Immerse the metal in a flux solution to remove any remaining oxides and prevent further oxidation during galvanising.
4. Galvanising: Galvanise the metal in a bath of molten zinc at 840 °F (449 °C). Zinc forms a coating on iron or steel.
5. Precision machining: Then cool the galvanised metal and treat it with a chromate conversion coating or other precision machining to improve its appearance and durability.
Hot dip galvanising is a common method for protecting steel structures from corrosion. This is an efficient and cost-effective method to extend the service life of metal structures.
