A rectangular tube is a hollow strip of steel, also known as a flat tube, flat square tube or square flat tube (as the name suggests). At the same time of bending and torsional strength, the weight is light, so it is widely used in the manufacture of mechanical parts and engineering structures. Rectangular pipe is a hollow square cross-section of light thin-wall steel pipe, also known as steel cooling curved profile. It is made of Q235 hot rolled or cold rolled strip or coil as the base material by cold bending processing and then high frequency welding made of square section shape and size of the section steel. In addition to the thickening of the wall, the corner size and the flatness of the edge of the hot rolled special thick wall square pipe reach or even exceed the level of the resistance welding cold formed square pipe.

Packaging and Shipping of Rectangular Steel Tube
Rectangular steel tubes are typically packaged in bundles or individual units and are shipped in wooden cases or steel crates. Depending on the size and weight of the tubes, they can also be shipped in large wooden pallets. The tubes are usually wrapped in protective packaging such as bubble wrap or foam padding to prevent damage during transit.
Tracking information is typically provided to customers upon shipment of the tubes.
