S.S WELDED RECTANGULAR PIPES

Rectangular steel pipes and tubes are used in different industrial applications. These are used for accomplishing different purposes. The common areas, where these rectangular pipes and tubes are used are: supermarket racks, container fabrication, auto fabrication, motor cycles, doors and windows, industrial plant structure, bicycles, furniture etc. There are several parameters for defining the rectangular pipes and tubes.

These parameters are length, width, height, welding gap, radius, diameter etc. According to the nature of the requirements, the size of the rectangular steel pipes and tubes can be altered.

S.S WELDED SQUARE PIPES

In a large number of industries, square steel pipes are used and the production of this kind of pipes is increasing day by day. With compare to round steel pipes, square steel pipes are little more efficient because the square column is more efficient than the solid circular column.

The alloy used for manufacturing square steel tubes is carbon steel. 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.

The square steel pipes are used in a special configuration. Both the perpendicular sides of two square steel pipes are respectively aligned in perpendicular and parallel to the plane of the frame bodies. In this case, by butt-welding, the cross points of the bar members are joined along a short weld line.
