Square steel tube (or we can name it as square hollow section or
square steel pipe ) comes in different sizes, specifications and
wall thicknesses. Its uniformity makes it predictable to use and
visually appealing. It has a 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
into cold rolled square tube and hot finished square tube.
Nowadays, hot finished square tube is more popular when it comes to
some special projects such as MRT, Airport, Gym Stadium etc.
