Product Description

Rectangular steel tubing is a general term for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. 2 Inch Square Rectangular Tube is made by rolling strip of steel and then processing it. Generally, the strip steel is blanked, leveled, curled, and welded into round tube, and then rolled into square tube, and then cut into the required length.

Main Features

1. High structural strength: The square cross-section has excellent bending and compression resistance.

2. Light weight: Compared with solid steel, square steel tubes are lighter and easier to transport and install.

3. Easy installation: Square ectangular tube can be quickly assembled by welding, bolting, etc.

4. Neat appearance: The square cross-section design is simple and neat, suitable for decoration and furniture manufacturing.

5. Good processing performance: Easy to cut, drill, bend, and perform other subsequent processing.

Note: To improve the performance of steel, 390 can be added with trace elements such as vanadium, niobium, titanium, molybdenum, and ammonia

Yield-to-strength ratio of Class I products

Product yield strength grade	Outer perimeter mm	Wall thickness mm	Yield-to-strength ratio %
			Direct into the square	Direct into the square
235	≥800	12~22	≤80	≤90
345
390			≤85	≤90
Note: When the outer circumference is less than 800mm, the yield strength ratio can be determined by negotiation between the supply and demand parties.

Application

In the construction industry, rectangular steel tubing, with its high strength, lightweight, and ease of processing, is widely used in steel structural frames (such as factory columns and beams), curtain wall support systems (as a keel to fix glass or metal panels), staircases and handrails (balancing load-bearing capacity and aesthetic design), as well as roof trusses and temporary building structures (such as construction hoardings and exhibition hall frames). Its standardized dimensions and excellent bending and compressive strength make it a preferred material to replace traditional concrete or wood structures in modern construction. Furthermore, its weather resistance can be enhanced through galvanizing or spraying processes, adapting to diverse building needs.
