Galvanized Square Steel Tube

Description

Galvanized Square Steel Tube is a hollow square section steel tube with square cross-section shape and size made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil as blank, cold-bent and then welded by high-frequency welding, or a galvanized square tube made of pre-made cold-bent hollow steel tube by hot-dip galvanizing.

Classification of Galvanized Square Steel Tubes:

Galvanized Square Steel Tube is divided into hot-dip galvanized square tube and cold-dip galvanized square tube in terms of production process. It is precisely because of the different processing of these two galvanized square tubes that they have many different physical and chemical properties. In general, they have many differences in strength, toughness and mechanical properties.
Hot-dip galvanized square tube

Hot-dip galvanized square steel tube:

It is a square tube made by welding after curling steel plate or steel strip, and on the basis of this square tube, the square tube is placed in a hot-dip galvanizing pool after a series of chemical reactions. The production process of hot-dip galvanized square tube is relatively simple, and the production efficiency is very high. There are many varieties and specifications. This kind of square tube requires very little equipment and funds, which is suitable for the production of small galvanized square tube manufacturers. However, in terms of strength, the strength of this steel pipe is far lower than that of seamless square pipe.

Cold-dip galvanized square steel tube

Cold-dip galvanized square pipe uses the principle of cold-dip galvanizing on the square pipe to make the square pipe have anti-corrosion properties. Unlike hot-dip galvanizing, cold-dip galvanized coatings mainly use electrochemical principles for anti-corrosion, so it is necessary to ensure that the zinc powder is in full contact with the steel to produce an electrode potential difference, so the surface treatment of the steel is very important.

Since the galvanized square steel tube is galvanized on the square pipe, the application range of the galvanized square pipe has been greatly expanded compared to the square pipe. It is mainly used in curtain walls, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc.

Applications of Galvanized Square Steel Tubes:

Galvanized square steel tubes are primarily used in construction, machinery manufacturing, and energy and power industries, commonly found in steel structures, photovoltaic brackets, and municipal guardrails.

1. Construction Engineering: Galvanized square steel tubes are widely used for structural support and wiring protection in steel frame structures, curtain wall supports, scaffolding, and underground utility tunnels.

2. Municipal Facilities: Galvanized square steel tubes are commonly used to manufacture guardrails, streetlight poles, and signage brackets, ensuring both rigidity and resistance to weathering.

3. Energy and Power: Galvanized square steel tubes are an important material for photovoltaic brackets, power transmission towers, communication power grids, and transmission line supports.

4. Machinery Manufacturing: Galvanized square steel tubes are used in automobile chassis, boiler construction, equipment frames, and transmission support components, offering high dimensional accuracy and stable operation.

5. Agricultural facilities: Galvanized Square Steel Tube is suitable for greenhouse frames and agricultural irrigation systems, and its service life can reach more than ten years in high humidity environments.
