Square tube: the "steel skeleton" of modern engineering - analysis
Square tube is a metal product with excellent performance and wide applications, covering multiple industries such as construction, machinery, electronics, and automobiles.
This article introduces the definition, advantages and disadvantages, application fields, application cases, and development prospects of Square Tubes.
1、 Definition of rectangular tube
Square tube is a hollow section Steel made by cold bending or cold rolling strip steel and thin steel plate, with a cross-sectional shape of square or rectangle. The inner diameter, outer diameter, height and other dimensions of square tube have high precision, uniform wall thickness, diverse cross-sectional shapes, and advantages such as high strength, lightweight, corrosion resistance, and easy processing. It is widely used in fields such as construction, machinery, electronics, and automobiles.
2、 Application fields of square and rectangular tubes
Construction industry: Square and rectangular pipes are widely used in the construction industry, and can be used to make various building structure supports, brackets, railings, pipelines, etc. They can also be used to make various steel structure houses, bridges, etc.
Mechanical industry: Square and rectangular tubes are also widely used in the mechanical industry, and can be used to make mechanical components, conveyor belts, assembly lines, etc. They can also be used to make the shells and frames of various mechanical equipment.
Electronics industry: The application of square and rectangular tubes in the electronics industry is gradually increasing, which can be used to make various electronic product casings, brackets, heat sinks, etc.
Automotive industry: Square tube is also widely used in the automotive industry, and can be used to make frames, suspension systems, carriages, etc.
High precision: The inner diameter, outer diameter, height and other dimensions of the square tube have high precision, which can reach the higher precision level in GB/T12704-2006 standard and meet the high-precision requirements of various industries.
High efficiency:The wall thickness of square and Rectangular Tubes is uniform, and the cross-sectional shapes are diverse. Different production processes and equipment can be used for production, resulting in high production efficiency and fast processing speed.
Easy to process: Square and rectangular tubes can be cut, bent, welded, and other processing operations, which are simple and easy to master.
Corrosion resistance: Rectangular pipes can be treated with surface treatments such as galvanizing and painting to enhance their corrosion resistance, and can be used for a long time in various harsh environmental conditions.
4、 Application case of square rectangular tube
In the field of architecture, square and rectangular pipes can be used to make various building structural supports, brackets, railings, pipelines, etc., such as high-rise buildings, bridges, etc.
Mechanical industry: Square and rectangular tubes can be used to make mechanical components, assembly lines, etc., such as automated production lines, robotic arms, etc.
Electronics industry: Square tubes can be used to make shells, brackets, heat sinks, etc. for various electronic products, such as mobile phones, computers, etc.
Automotive industry: Square tube can be used to make frames, suspension systems, etc., such as cars, SUVs, etc.
Square rectangular tube is a term for square and rectangular pipes, which are rolled from strip steel through processing. Generally, the strip steel is unpacked, flattened, curled, and welded to form a round tube, which is then rolled into a square tube and cut to the required length.
In the engineering field, square and rectangular pipes have many applications, such as galvanized welded square pipes for low-pressure fluid transportation, welded square pipes for mining fluid transportation, large-diameter welded square pipes for low-pressure fluid transportation, and stainless steel welded square pipes for mechanical structures.
Large caliber square tube, also known as rectangular square tube, is divided into square square tube, open mouth square tube, wavy square tube, etc. according to cross-sectional area. According to the production process, it is divided into hot-rolled seamless splicing large caliber square tube, cold drawn seamless splicing large caliber square tube, extruded seamless splicing large caliber square tube, and welded large caliber square tube.
Square tube has a wide range of applications, including construction, machinery, shipbuilding, electricity, agriculture and animal husbandry, warehousing, fire protection, home appliances, and many other industries. It can be said that it is an indispensable type of steel for the development of modern industry.
