Product Introduction:

Seamless Hot-Dip Galvanized Square Tubes are square-shaped steel pipes with hollow cross-sections, formed by cold-drawing and extruding seamless steel pipes.

They differ fundamentally from welded galvanized square tubes, which are made by coiling and welding strip steel into round pipes before shaping them into square/rectangular tubes.

Galvanized square & rectangular tubes (SHS & RHS) are widely used for fluid transportation, structural frameworks, and mechanical applications due to their high strength and corrosion resistance.

Key Features:

 Seamless Pipes – No welds, higher pressure resistance, ideal for high-stress mechanical and hydraulic systems.

 Hot-Dip Galvanizing (Zinc Coated) – Enhanced rust prevention for outdoor/industrial use.

 Wall Thickness Impact –

Thicker walls = More economical & durable.

Thinner walls = Higher precision requirements, increased production costs.

 Challenges of Seamless Pipes –

Lower dimensional accuracy (uneven wall thickness, surface imperfections).

Requires offline inspection and straightening.

Excels in high-pressure, high-strength, and structural applications.
