Parameter of GI Square Tubes
Galvanized square tubes are square pipes made of steel strips or steel plates, which are formed by cold bending and then galvanized. Production process: Firstly, precise cutting and edge treatment are carried out on the raw materials, and then the steel strip or plate is gradually bent into a square cross-sectional shape through cold bending forming equipment and welded into pipes. Afterwards, galvanizing treatment can be carried out using hot-dip galvanizing or electroplating processes to form a uniform layer of zinc on the surface of the square tube. Commonly used in the fields of architecture, industry, and agriculture.

Features of GI Square Tubes
Square cross-section endows the galvanized square pipe with enhanced stability and load-bearing capacity in structural applications. In comparison with circular pipes, it exhibits a superior ability to distribute stress when subjected to axial pressure and lateral loads, thereby minimizing the propensity for bending deformation.
Zinc coating on the surface furnishes robust anti-corrosion protection, effectively safeguarding the base material of the square pipe from oxidation and corrosion. This property enables the galvanized square pipe to sustain a favorable condition over an extended period, prolonging its service life and curtailing the expenses associated with maintenance and replacement.
Sophisticated processing technologies ensure high-precision dimensional accuracy of the side length, wall thickness, and other parameters of the square pipe. Moreover, the four corners are precisely formed at right angles, conferring a regular and well-defined shape.
Carbon galvanized square steel pipe demonstrates excellent processability, facilitating effortless execution of various processing operations such as cutting, drilling, welding, and bending. It can be flexibly fabricated in accordance with specific design requirements, affording versatility in engineering applications.
