During production of   galvanized rectangular steel pipe , the steel is rolled into a square shape, bent and welded, and then galvanized. Thanks to galvanization, these square pipes can withstand even the most adverse weather conditions - especially moisture - for a long time. Galvanized rectangular 4-sided pipes are suitable for many indoor and outdoor applications. Whether in your own home, apartment or neighbor's garden, our galvanized steel rectangular pipes are used in many commercial sectors. Galvanized rectangular steel is very stable due to its geometry and is therefore suitable as a modern & versatile structural element for numerous professional as well as hobbyist applications in the outdoor and indoor areas - for example: for stands and exhibition stands for balustrades on balconies, terraces and stairs for the skeleton construction of tables, shelves, benches and other furniture in the construction of machinery and equipment Changsha Xiangjia Metal Materical Co., Lt...

What are the calculation methods for the vertical bearing capacity of the  rectangular tube : 1. Calculate the compressive stress, which is the compressive stress generated by the vertical pressure acting on the cross section of the rectangular tube. The pressure (in N) divided by the cross-sectional area of the rectangular tube (in m square). The compressive stress should be less than the allowable stress of the material. 2. Calculate the stability. The tube stability calculation is complicated. It depends on whether the connection method is fixed at both ends or fixed at one end and hinged at the other end. It is estimated that you do not only use 1 column, so it can be simply calculated as a fixed connection at both ends. Simple calculation of critical pressure: P=(4*n*Pi^2*E*I)/[(L/2)^2]. N:The number of columns; pi^2: the second power of the shot; E: modulus of elasticity; I: moment of inertia; and L: column length. Those are simple calculations. Safety factors and seismic loa...
