What is square tube?
Square tube is a term for square tube and rectangular tube, that is, steel tubes with equal and unequal side lengths.
It is made of rolled strip steel after process treatment.
Generally, the strip steel is unpacked, leveled, crimped, welded to form a round pipe, then rolled into a square pipe from the round pipe and then cut into the required length.
Types of square tube
Square square tubes are divided into hot-rolled seamless square tubes, cold drawn seamless square tubes, extruded seamless square tubes and welded square tubes according to the production process.
The welded square pipe is divided into:
- Divided by process – arc welding square pipe, resistance welding square pipe (high frequency and low frequency), gas welding square pipe and furnace welding square pipe
- Divided by the weld seam – straight welded square pipe and spiral welded square pipe.
Square Tube Weight Calculator
According to cold drawn special-shaped steel pipe (GB / T 3094-2012), the general length of square steel pipe is 2000mm ~ 9000mm, and the supply can be delivered according to fixed length or double length.
In the market, square steel pipes can be delivered according to actual weight or theoretical weight.
When delivered by theoretical weight, the density of steel pipe is 7.85g/cm³.
