High strength: the square pipe has high tensile, compressive and bending strength, and can withstand large loads and pressures, which is suitable for the production of various structural parts. Good stability: the square tube has high dimensional accuracy, stable structure, and is not easy to deform, which can ensure that the processed products have high accuracy and stability. Good corrosion resistance: square pipe after galvanized, spray and other surface treatment, has good corrosion resistance, can adapt to a variety of complex environments. Low cost: The production cost of square tubes is relatively low, and it is easy to process, suitable for large-scale production and applications.
