The square tube models we can produce are as follows, and the full size is shipped from stock:
1.GB/T 6728-2018: This is China's national standard, which specifies the specifications, dimensions, shapes, technical requirements and test methods of cold-formed rectangular square tubes. Common specifications include 100×50×5, 120×60×5, 140×70×6, 160×80×6 and 180×90×7, etc.
2.JIS G3466: This is the Japanese industrial standard, which specifies the specifications, dimensions and tolerances of hot-rolled rectangular square tubes. Common specifications include 50×25, 75×30, 100×40, 125×50 and 150×60, etc.
3.ASTM A500: This is the American Society for Testing and Materials standard, which specifies the specifications, dimensions and performance requirements of cold-formed rectangular square tubes. Common specifications include 1x1, 2x1, 3x1, 4x1 and 6x1, etc.
Square tubes of different materials and their application areas: Plain carbon steel: including Q195, Q215, Q235, SS400, 20# steel and 45# steel, etc. These materials are commonly used for general engineering and structural purposes.
Low alloy steel: covering materials such as Q345, 16Mn, Q390 and ST52-3. These materials have higher strength and durability and are often used in situations requiring higher strength requirements.
Common size ranges and application scenarios of square tubes: Square tubes: The diameter ranges from F30×30mm to 500×500mm (or larger), and the wall thickness is usually 3mm to 25mm. Suitable for industries such as construction, machinery and furniture.
Rectangular tube: The diameter ranges from J30×40mm to 600×400mm (or larger), and there are also product specifications of 20×40mm to 400×600mm (or larger), and the wall thickness is also 3mm to 25mm. Suitable for various structures and engineering needs.
