China Wuxi hot galvanized sheet square pipe manufacturer produces various types of hot galvanized square pipe and hot galvanized rectangular pipe Norge

Quick Detail:

Hot-dip galvanized square pipe and hot-dip galvanized rectangular pipe are common metal products, which are obtained by coating a layer of zinc on the surface of ordinary square pipe or rectangular pipe after a series of treatment processes.

The so-called hot-dip galvanizing refers to the pickling treatment on the surface of the steel, the removal of impurities such as oil and oxides, and then immersed in the galvanized tank that is pre-heated to the appropriate temperature and dissolved zinc powder. In this process, due to the steel and dissolved zinc powder liquid contact and reaction to produce a chemical reaction, so that the surface of the steel generated a strong and dense metal alloy film - the so-called "galvanized" layer.

Description:

Hot-dip galvanized square pipe and hot-dip galvanized rectangular pipe are common metal materials with many advantages. First, they are hot-galvanized to form a strong and durable protective layer of zinc and iron on the surface. This protective layer can effectively prevent corrosion reactions caused by contact between steel and oxygen, moisture and other substances in the external environment, thus extending the service life of square and rectangular tubes.

Secondly, because the surface of the square and rectangular pipes after hot dip galvanizing is smooth and flat, and the protective layer is coated with a uniform thickness, they have good decorative properties. Whether used indoors or outdoors, these galvanized pipes provide a beautiful, high-quality appearance for buildings or other works.

Applications:

In the construction field, hot-dip galvanized square and rectangular pipes are often used as structural support materials. Due to their high strength and stable properties, they can withstand large loads and are able to maintain a long-term stable structure. This makes them ideal for important components such as building frames, beams and columns. In the furniture manufacturing industry, it can be used as a furniture frame or support structure; In the field of power equipment manufacturing, it can be applied to cable protection bushing. Whether in the construction, or manufacturing industry, hot-dip galvanized square and rectangular pipes play an important role. They meet the material quality and functional requirements of various industries by providing excellent corrosion resistance, high strength and good sealing performance.
