Product description

Product details

Equipped with a dense hot-dip zinc coating, the square tube provides outstanding corrosion and rust resistance, performing reliably in humid, coastal and outdoor weather conditions.

The zinc layer offers sacrificial anode protection; even minor surface scratches during transportation or installation will not easily cause rusting of the base steel material.

The zinc coating is firmly bonded to the steel substrate, resisting peeling, cracking and chipping when undergoing cutting, drilling, bending and other common fabrication processes.

Features stable mechanical properties including high yield strength and good structural rigidity, capable of bearing heavy loads and maintaining structural stability for frame and support applications.

Neat square cross-section with straight edges and uniform dimensions, convenient for assembly, connection and welding, greatly improving construction and installation efficiency.

Long service life with low maintenance requirements; it avoids frequent anti-rust repainting and complicated upkeep work, saving long-term labor and maintenance costs.

Excellent cost-effectiveness compared with uncoated steel tubes, reducing replacement frequency and lowering the total lifecycle cost of building and engineering projects.

Available in a wide range of sizes, wall thicknesses and zinc coating weights, widely applicable in construction frameworks, guardrails, machinery supports and agricultural facilities.
