Square and Rectangular Tubes/Hollow Sections

Square and rectangular tubes, also known as hollow structural profiles (HSS), are used in a variety of structural and mechanical applications. The following are the standards, classifications and applications of square and rectangular tubes: standard: Square and rectangular pipes are manufactured to specific standards set by organizations such as ASTM International, the American Society of Mechanical Engineers (ASME), the European Committee for Standardization (CEN), and other national and international standards bodies. 

Common standards for square and rectangular pipe include ASTM A500 for structural pipe, EN 10219 for cold-formed welded structural hollow sections, and JIS G3466 for general structural welded steel pipe. 

Classification: Square and rectangular tubes can be classified according to different criteria: Manufacturing Methods: These pipes can be produced through a variety of methods, including hot rolling, cold forming and welding processes. 

Sizes and Dimensions: Square and rectangular ducting are available in a variety of standard sizes and dimensions, as well as custom sizes to meet specific design requirements. Material Grades: These pipes are available in different material grades including carbon steel, alloy steel, stainless steel and other structural steel grades. 

Advantages : They offer the advantages of uniform strength, aesthetics, and cost-effective manufacturing. It is important to select square and rectangular pipes that meet the required standards, material specifications and performance standards for your specific application. Additionally, factors such as corrosion resistance, weld-ability, and dimensional tolerances should be considered when selecting these pipes for a specific project.
