How to Choose the Right Square and Rectangular Tube?

What is a square and rectangular tube?

Square tube or rectangular tube is a tube with a square or rectangular cross-section. Common materials include ordinary carbon steel, alloy steel, stainless steel, etc. Square or rectangular tubes are more suitable for use than ordinary round tubes in some scenarios because of their square or rectangular cross-section. How to choose the appropriate square and rectangular tube? The Permanent Steel square and rectangular tube manufacturer will introduce it to you in detail below.

Choose the right square tube according to your needs:

1. Material selection
Commonly used materials for square and rectangular tubes include steel, aluminum, stainless steel, etc. According to the specific application environment and requirements, select the corresponding materials. Steel has the characteristics of high strength, wear resistance and corrosion resistance, and is suitable for places with high load-bearing requirements. Aluminum is light, easy to process, and resistant to oxidation, and is suitable for places with lighter requirements. Stainless steel has the characteristics of high temperature resistance and corrosion resistance, and is suitable for special environments. Common standard materials for square and rectangular tubes include EN 10210, EN 10219, ASTM A500, ASTM A513, ASTM A36, etc. The use of high-quality raw materials can ensure the quality and stability of square and rectangular tubes.

2. Size selection
Choose the right size based on your specific needs. The size of square and rectangular tubes is usually determined by two parameters: width and height. Common specifications include 25x25mm, 50x50mm, 100x100mm, etc. It is necessary to consider the space restrictions of the place of use, the direction of force and the load-bearing requirements of the specific application. Determine the length, width, thickness and other specifications of the square and rectangular tube according to the design requirements.

3. Thickness selection
The thickness of the square tube determines its load-bearing capacity and bending resistance. The thicker the thickness, the higher the strength, and is suitable for places with higher load-bearing requirements. Common thicknesses include 1.5mm, 2.0mm, 3.0mm, etc., which can be selected according to specific needs.

4. Surface treatment
Square and rectangular pipes are usually surface treated to increase their rust and corrosion resistance. Common surface treatment methods include hot dip galvanizing and spraying. Select the appropriate surface treatment method based on the specific environment and requirements.

5. Quality certification and quality testing
You should choose manufacturers with good reputation, exquisite production technology and stable product quality to ensure reliable quality. Pay attention to the stability and various indicators of the material, not just the price factor. When purchasing square and rectangular pipes, national standards and quality standards should be strictly implemented, and necessary spot checks and other tests should be conducted to ensure that the purchased square and rectangular pipes meet the usage requirements. For example, there are no obvious cracks, pores, slag inclusions, welding burrs and other defects on the outer surface of the steel pipe.

6. Price comparison
While considering the above factors, you also need to compare the prices of square and rectangular pipes from different suppliers or brands according to your budget, and consider the final purchase based on cost performance.

Advantages and features of square rectangular tubes:
1. High strength: Compared with circular pipes, square and rectangular tubes have a more stable cross-section and therefore higher strength.
2. Good processing performance: Square and rectangular tubes have good processing performance and are easy to drill, weld and cut.
3. Good sealing: The cross-section of the square and rectangular tube is relatively closed, so it can better protect the items inside the tube. It is suitable for storage, transportation and other scenarios, and it can withstand high pressure.
4. Beautiful appearance: The cross section of square and rectangular tubes is regular square or rectangular, which is more three-dimensional and more beautiful than circular tubes.
5. Easy to install: Square and rectangular tubes also have the characteristics of simple structure, easy installation and cleaning.

Main application scenarios of square and rectangular tubes:
1. Construction industry: Square and rectangular tubes are often used in building structures, such as stair handrails, columns, bridges, etc.
2. Machinery manufacturing: Square and rectangular tubes are widely used in the machinery manufacturing industry to make machine tool beds, brackets, tracks, transmission shafts, etc.
3. Transportation: Square and rectangular tubes can also be used as highway guardrails, billboard racks, etc., and can also be used to make truck racks, rail transit subway lines, etc.
4. Petrochemical industry: Square and rectangular tubes can be used in various pipeline systems, such as liquid transportation in petroleum and chemical pipelines, and gas transportation in gas pipelines.
