Galvanized steel tube leverage dual advantages in corrosion resistance and structural integrity. Their distinct cross-sectional forms—round pipes and square/rectangular pipes—precisely meet diverse demands ranging from fluid transportation to framework support. Round pipes, with their uniform stress distribution and smooth inner walls, specialize in conveying water, gas, oil, and other fluids. Square and rectangular pipes, meanwhile, excel as load-bearing, guardrail, and framing materials due to their superior bending stiffness, flat surfaces, and ease of connection.
Civil Construction Applications
Civil projects prioritize safety, aesthetics, and cost-effectiveness. Round tubes ensure stable delivery of daily-use media, while square pipes construct secure and comfortable living frameworks.
Applications of Galvanized Round Tubes
- Indoor Water Supply: Smooth inner walls minimize friction, while the galvanized coating prevents rust contamination. We offer stock pipes and custom cuts from 1 to 12 meters, with pre-tapped ends for rapid installation.
- Gas Service Lines: Rigorous sealing and pressure testing guarantee absolute safety. Each batch includes a gas tightness test report.
- Heating System Piping: Pressure-resistant and heat-tolerant, suitable for hot water circulation. We offer internal descaling processes and guarantee material integrity without brittle fracture at northern temperatures as low as -30°C.
Applications of Galvanized Square Tubing
