Description

Square tubes are tubular materials with a rectangular cross-section, fabricated from high-strength steel plates through welding or seamless processes. They have a unique shape, smooth surface, and a sturdy internal structure. They possess high strength, excellent compressive resistance, and good corrosion resistance, and can be used in various harsh environments. 
The dimensions and specifications of square tubes are diverse. Common sizes include 20×40mm, 30×50mm, 50×50mm, etc. The length is usually fixed, but can also be customized according to customer requirements. The price depends on factors such as size, thickness and material, and the weight can be calculated using a formula. 
Square tubes have a wide range of applications. In the construction field, they are commonly used in building frames, large-span roof structures, stair handrails, etc.; in the mechanical manufacturing industry, they are used as mechanical parts in automobile manufacturing, mechanical equipment manufacturing, etc.; in the furniture manufacturing sector, they are ideal materials for furniture frames, bed frames, sofas, etc.
