Why Choose Our Galvanized Steel Pipe for Fencing?

✅ Superior Corrosion Resistance - The hot-dip galvanizing process creates a metallurgical bond between zinc and steel, ensuring a thick, durable coating that won't peel, chip, or crack over time.

✅ High Strength & Structural Integrity - Manufactured from high-quality steel grades with excellent tensile strength and load-bearing capacity, ideal for fence posts, rails, and framework.

✅ Smooth, Uniform Surface Finish - Bright silver finish with no burrs, providing both aesthetic appeal and added protection.

✅ Easy Installation - Standardized dimensions and uniform wall thickness make cutting, welding, and assembly quick and easy.

✅ Cost-Effective - Lower lifetime cost compared to painted or untreated steel pipes due to reduced maintenance and replacement needs.

Product Info

The hot-dip galvanized tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. The steel pipe matrix and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant structure of a zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base. Therefore, its corrosion resistance is strong.

Application

At present, the iron pipe used for gas, greenhouse and heating is also a galvanized pipe. The galvanized pipe is used as a water pipe. A large amount of rust is generated in the pipe. The yellow water flowing out not only pollutes the sanitary ware, but also contains bacteria that grow on the uneven inner wall, causing corrosion in the water. The heavy metal content is too high, which seriously endangers the health of the human body. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and banned galvanized pipes. The Ministry of Construction and other four ministries and commissions also issued a document clarifying that galvanized pipes will be banned from 2000. At present, galvanized pipes are rarely used in cold water pipes in new residential areas. Some districts use galvanized pipes for hot water pipes.
