Square steel tube(or we can name it assquare hollow sectionorsquare steel pipe) comes in different sizes, specifications and wall thicknesses.
Its uniformity makes it predictable to use and visually appealing.
It hasa high weight-to-strength ratio. Compared to round steel pipe, square steel tube is more
efficient, stronger and durable.
There are two types of square steel tube:welded and seamless.And price for seamless square tube is commonly higher than that of
welded type. Welded square tube is made of steel plates or steel
coils. Seamless square tube is made of round tubes, which always
gives the finished products high mechanical prosperities.
From the production technique point of view, we can also divide it
intocold rolled square tubeandhot finished square tube.Nowadays, hot finished square tube is more popular when it comes tosome special projects such as MRT, Airport, Gym Stadium etc.
