Description


Galvanized square pipe is a hollow square section steel pipe with a specific shape and size. Its production process mainly includes two steps: first, the use of hot or cold rolling method to process galvanized strip steel or galvanized coil into billet; These blanks are then machined by cold bending to form a square cross-section shape.

In the first step, a hot or cold rolling method is used to treat galvanized strip or galvanized coil. These materials become harder and more durable after being treated at high or low temperatures. This process can not only change the physical properties of the material, but also coat its surface with a galvanized layer, thereby increasing its corrosion resistance.

In the second step, these treated billets are cold-bent into the desired shape. This process requires precise control to ensure that the final galvanized square pipe has the correct size and shape. In this process, the inside of the galvanized square pipe will form a hollow structure, which can effectively reduce the weight of the steel pipe, but also increase its strength and stability.

Finally, these cold-bent galvanized square pipes are welded together at high frequency to form a complete steel pipe. This process requires the use of high-frequency electric current, through the heat generated by the current to melt the joint part of the steel pipe, so as to achieve a seamless connection.

Another method of manufacturing galvanized square rectangular pipe is to first make cold formed hollow steel pipe, and then hot dip galvanized. The advantage of this method is that the size and shape of the galvanized square tube can be controlled more precisely, and it can also ensure that the galvanized layer on its surface is uniform and the thickness is moderate.
