Square
steel pipes are used in a various industries. Today, the production of these
pipes increased enormously. The square column in the square pipes are more
efficient than the solid circular column which is why comparing to round
steel pipes, the square steel pipes are stronger and durable as well. The
alloy used for manufacturing square steel tubes is carbon steel.
In a traditional space structure building, circular hollow section members
were used. Then, the ends of the curve surface were joined by welding. This
traditional process takes long time and seems to be difficult. To solve the
problem the engineers started using square steel tubing. These square steel
pipes are being used in a special configuration. The square steel pipes are
respectively aligned in perpendicular and parallel to the plane of the frame
bodies then, the cross points of the bar members are joined along a short
sealed line by butt welding.


These steel tubes are used in structural projects, shelves, racks,
trailers and in ornamental purpose. The framework made by square steel
tubes, is used for providing support to the roof. This framework is also
used as roof top ventilation baffles.
