Features of Pre-Galvanized Rectangular Tubes
- High structural stability. The design of the rectangular cross-section enables it to perform outstandingly when subjected toaxial pressure, lateral loads, and torque. Compared with circular pipes, rectangular pipes can provide greater moments ofinertia and section moduli in specific directions, thereby more effectively resisting bending and torsional deformations.
- Have excellent anti-corrosion performance. The zinc layer on the surface is the key to its anti-corrosion. Whether in specialenvironments or ordinary atmospheric environments, galvanized rectangular steel tubes can maintain structural integrityand service performance for a long time and extend the service life.
- Advanced production processes ensure that galvanized rectangular steel tubes have high dimensional accuracy. Theerrors of dimensional parameters such as side lengths, wall thicknesses, and diagonal lengths are controlled within a verysmall range. The four corners are precisely right angles, and the tube body is regular and straight.
- During the processing, as long as the operation is standardized, the integrity of the zinc layer can be well maintained. Theprocessed rectangular steel tubes still have good anti-corrosion performance, which provides great convenience for onsite construction and customized processing.
- Due to its unique structural characteristics, excellent anti-corrosion performance, and good processability, galvanizedrectangular steel tubes are widely used in many industries and fields.
