RUNYING Steel Group is a leading Tangshan manufacturer and export supplier of Hot-Dip Galvanized Steel Round Pipes and Tubes (GI Pipes). Manufactured from continuous electric resistance welded (ERW) or seamless carbon steel base pipes, our galvanized pipes feature an heavy-duty zinc coating (≥60g/㎡, 85um thickness), delivering dual anti-corrosion protection compliant with ASTM A53, BS 1387, and BS EN 10255 international standards.

Designed for fire sprinkler protection, municipal water supply, structural scaffolding, HVAC piping, and agricultural greenhouse structures, our galvanized steel round tubes provide a reliable 20 - 30 year maintenance-free service life in challenging atmospheric and marine environments.

Technical Specifications (Welded vs. Seamless GI Pipes)

Key Performance Advantages

1, Triple Anti-Corrosion Defense:

Combines sacrificial cathodic protection, a metallurgical Fe-Zn intermetallic alloy layer, and a dense outer pure zinc barrier to resist atmospheric oxidation and humidity.

2, Installation-Ready Custom Pipe End Fabrication:

 · Threaded & Coupled (T&C): Precision BSP/NPT threads with protective plastic caps and heavy-duty steel couplings.

 · Victaulic Grooved Ends: Fast, bolt-less mechanical coupling for high-pressure fire sprinkler pipe networks.

 · Beveled Ends (30° - 35°): Prepared for immediate field butt-welding.

3, Compliant with Global Structural & Fire Ratings:

Meets strict pressure and safety standards for Fire Protection (BS EN 10255), Structural Scaffolding (AS/NZS 1163), and Water Utility Systems.

Universal Industrial Applications

 · Fire Sprinkler & HVAC Systems: High-pressure fire protection water mains and HVAC chilled water circulation piping.
