The difference between rectangular steel pipe and square steel pipe

Rectangular steel pipe
Common points:
Rectangular steel tubes and square steel tubes are hollow elongated steel materials, the difference being that they have different cross sections, one is a rectangle and the other is a square. Here, you have to say: Is a square not a special rectangle? Yes, so a square steel tube is a rectangular steel tube, rectangular steel tube can be applied, rectangular steel tube can also be used, but the rectangular steel tube is suitable for occasions It is wider than square steel pipe. It can be used in construction, machinery manufacturing, iron and steel construction projects, shipbuilding, solar power stand, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, car chassis, airports, etc. The use is very extensive.
Square/Rectangular hollow steel tube  is a section steel of square cross-section shape made of hot-rolled or cold-rolled strip steel or coiled plate made by cold bending and then high-frequency welding. Hot-rolled special thick-walled square tubes, except for the thickening of the wall thickness, have corner sizes and edge flatness that have reached or even exceeded the level of resistance-welded cold-formed square tubes. The square steel pipe is usually formed by unfolding, flattening, curling, welding and other processes to form a round pipe, and then rolling into a square pipe from a round pipe and then cutting into a desired length. In addition, the pipe is divided into seamless steel pipe welded steel pipe (seamed pipe), which is generally formed by extruding a seamless pipe.
