Galvanized square tubes are a type of metal pipe that has undergone galvanization treatment and are mainly made of carbon steel. It has a square cross-section and is widely used in fields such as construction, machinery, automobiles, Bridges, and power. Galvanizing treatment can effectively enhance the corrosion resistance of square tubes and extend their service life. Galvanized square tubes have a smooth surface, precise dimensions, are easy to install, and possess excellent mechanical and welding properties. According to different usage requirements, galvanized square tubes can offer a variety of wall thickness and size options to meet diverse engineering applications.

Our advantages
Tianjin Kun Yu JuyixiangTechnology co., Ltd.
Easy to install
Standardized specifications: Common side lengths range from 20×20mm to 400×400mm, and wall thicknesses from 0.8mm to 20mm, making them easy to purchase and match. The connection is flexible and supports welding, bolt connection or snap fixation, meeting the requirements of quick assembly.
Long service life
Environmental tolerance: It can last for 30 to 50 years in general atmospheric environments. Regular maintenance is required in industrial or coastal environments. Low maintenance cost: After the galvanized layer is damaged, it can be repaired by zinc replenishment without frequent replacement.
Economy and Environmental Protection
High cost performance: The initial cost is higher than that of ordinary steel pipes, but it saves maintenance and replacement costs in the long run. Recyclability: Both steel and zinc can be 100% recycled, meeting the requirements of sustainable development.
Applications

Construction Industry
Galvanized square tubes are widely used in the construction field and can be used to make doors and Windows, railings, stairs, scaffolding, building structural components (such as beams, columns, roof trusses, ceilings, walls, etc.) as well as supports and frames in curtain wall projects. Its excellent corrosion resistance and aesthetic appeal make it the preferred material in the construction industry.

Electric Power Industry
It also has important applications in the power industry and can be used to make power facilities such as utility poles, transformer frames, and transmission towers. Its excellent electrical conductivity and corrosion resistance ensure the safe operation of power facilities.

Agriculture
In the agricultural field, galvanized square tubes are used to make greenhouse supports, fences, farm tools and pipes in water conservancy projects (such as agricultural irrigation water systems). Its corrosion resistance and light weight make it the preferred material for agricultural facilities.

Chemical Industry
In the chemical industry, galvanized square tubes can be used to make pipes, containers, instruments and meters and other chemical equipment. Its excellent corrosion resistance and pressure-bearing capacity ensure the safe operation of chemical equipment.
announcements
Welding impact: High-temperature welding may damage the galvanized layer, and zinc replenishment or pre-galvanizing process should be selected in the later stage.
Transportation protection: Avoid scratches on the coating and prevent the spread of local rust.
Galvanized square tubes, with their durability, strength, and cost-effectiveness, have become the preferred alternative to traditional materials in engineering. The specific selection should be comprehensively considered based on environmental conditions, load requirement,s and budget.
