What are the advantages of galvanized square pipe?

Galvanized square pipe is a common steel pipe material. It has the advantages of anti-corrosion, durability, high strength, etc. Next, let us learn about the relevant knowledge about galvanized square pipe.

1. Production process of galvanized square tubes

Galvanized square pipes are made by hot-dip galvanizing the surface of ordinary square pipes, that is, immersing the square pipes in molten zinc liquid so that the surface of the steel pipes is covered with a layer of zinc to achieve the anti-corrosion effect. The main production process includes the following steps:

1. Product pretreatment: The surface of the square tube is pickled, degreased, and rust removed. The main purpose of this step is to ensure the cleanliness and smoothness of the surface of the square tube.

2. Hot-dip galvanizing: Dip the pre-treated square tube into the molten zinc liquid for hot-dip galvanizing. During this process, zinc reacts chemically with the surface of the steel pipe to form a zinc-iron alloy layer, and then a pure zinc protective layer is formed on the surface of the zinc-iron alloy layer.

3. Pre-factory inspection: Conduct appearance inspection, thickness inspection, chemical composition inspection and other inspections on galvanized square pipes to ensure that the quality of the products produced meets standard requirements.

2. Advantages of galvanized square pipe

1. Good anti-corrosion performance: The surface of galvanized square pipe is covered with a zinc layer, which is not easily oxidized and corroded, and can be used for a long time in harsh environments such as moisture, acid and alkali.

2. Strong durability: Galvanized square pipe has high strength and hardness, can withstand greater force, and has a long service life.

3. Convenient construction: Galvanized square pipes are light in weight, easy to cut, weld and install, and are easy to construct.

4. High aesthetics: The surface of galvanized square tube is smooth and bright, and has good decorative effect.

2. Application fields of galvanized square tubes

1. Construction field: Galvanized square tubes are often used in building structures, such as stair handrails, railings, steel structures, roof trusses, etc. Its weather resistance ensures long-term use in outdoor environments and its beautiful appearance.

2. Pipeline system: Galvanized square pipe can be used in pipeline systems for transporting liquids, gases, etc. Such as water supply pipelines, gas pipelines, etc.

3. Agricultural field: Galvanized square pipes are also commonly used in agricultural facilities, such as greenhouses, irrigation systems, etc. Galvanized coatings can effectively resist moisture and corrosion in agricultural environments, improving the durability of facilities.
