As the professional manufacture, we would like to provide you Pengfa Common Carbon Steel Square Rectangular Pipe. Hardness is a pointer to measure the degree of hardness of metal materials. The most commonly used method to determine the hardness of square rectangular tube in production is the pressing hardness method. It is to press the surface of metal materials to be tested with a certain geometric head under a certain load, and test its hardness value according to the degree of being pressed.
As the professional manufacture, we would like to provide you Pengfa Common Carbon Steel Square Rectangular Pipe. Rectangular tube use: Galvanized Square Rectangular Pip is the name of square tube and rectangular tube, and the strip steel is processed and rolled. Generally speaking, the strip steel is formed into a round tube by disassembly, flattening, crimping and welding, and then the round tube is rolled into a square tube, and then cut to the required length.
Large-diameter rectangular tubes, also known as rectangular tubes, are divided into square tubes, open-mouthed square tubes, corrugated square tubes, etc. according to the cross-sectional integral. Extruded seamlessly spliced large-diameter rectangular tubes, welded large-diameter rectangular tubes. Galvanized Square Rectangular Pip is a steel pipe with equal and unequal side lengths. If it is subdivided, it can be divided into square tube and rectangular tube. This is because the area of the cross street is different, the square tube is a square tube, and the rectangular tube is a rectangular tube.
