Galvanised square and rectangular pipe is a designation for square and rectangular pipes, which are steel pipes with equal sides. It is made of strip steel rolled through a process. Generally, the strip steel is unwrapped, flattened, curled, welded to form a round tube, and then rolled from the round tube into a square tube, and then cut the required length.

Seamless square tube has excellent extrusion strength, ductility, plastic deformation, welding and other performance, with excellent ductility, its aluminium alloy layer and the steel base of the tight connection, can carry out cold extrusion, cold rolling, etc., with excellent plasticity, cable bending and other forming does not destroy the plating layer, applicable to the general production and processing, such as perforation, laser cutting, welding, cold-drawing and other processing techniques.

Key characteristics related to seamless square tube:

Anti-rust treatment, anti-corrosion - zinc dipping layer, zinc-rich phosphating treatment layer, electrostatic induction plating have excellent anti-rust treatment of the actual effect. Seamless square tubes are generally able to ensure that they do not rust or corrode for thirty years in extreme natural environments.

Strong weathering electrostatic powder coating process selects solid powder condensation at high temperatures, such powder characteristics of liquid architectural coatings including architectural coatings within the characteristics of a very balanced. As a result, seamless square tubes have excellent anti-ultraviolet light maintenance, in the long-term sunlight exposure is not easy to fade.

Anti-tampering: Anti-tampering fittings and pipelines are tested by international technical standards, and all kinds of index values are in line with international industry standards.
