50*120 square tube

50*70 square tube

50*80 square tube

**Introduction to the Three Types of Square Tubes:** **1. 50×120 Square Tube** 1. Dimensional Features: - With side lengths of 50mm and 120mm, it boasts a larger cross-sectional size and a relatively high height, which offers good bending and torsional resistance. - The 50mm width ensures stability and facilitates connection with other components. 2. Applications: - In building structures, it can serve as main load-bearing members like beams and columns, suitable for large-span spaces. - In the industrial sector, it can be used to manufacture frames and supports for large equipment, capable of withstanding heavy loads. - In the production of outdoor facilities like billboards and light boxes, it acts as the primary supporting structure, offering good stability and wind resistance. **2. 50×70 Square Tube** 1. Dimensional Features: - With a smaller cross-sectional size, the combination of 50mm and 70mm side lengths makes the square tube lightweight, easy to handle and install. - Suitable for situations with low space requirements but needing certain strength and stability. 2. Applications: - In interior decoration, it can be used as ceiling joists, partition frames, etc., occupying minimal space while providing structural support. - In the manufacturing of small equipment enclosures, such as distribution boxes and control cabinets, it meets the requirements for protection and support. - It is also widely used in gardening facilities, small shelves, and more. **3. 50×80 Square Tube**

1. Dimensional Features: - Sizes ranging between 50x70 and 50x120 offer versatility. - A relatively tall height of 80mm provides good bending resistance, while a width of 50mm ensures stability. 2. Applications: - In some medium-sized building structures, they can serve as secondary beams, purlins, etc., to share part of the load. - In logistics equipment like medium-sized shelves and forklift frames, they meet the requirements for load-bearing and stability. - In the production of advertising display racks, bulletin boards, etc., they act as the main structural framework, offering good appearance and practicality.
