Product Overview

Galvanized Ringlock Scaffolding Pipe is hot-dip galvanized ring lock modular scaffolding tube, manufactured from Q355 high-strength carbon steel, compliant with EN12811 and GB/T 13793 standards. Designed specially for ringlock modular scaffolding systems, it adopts hot-dip galvanizing surface treatment with zinc coating weight ≥200g/m², achieving 1–3 years outdoor service life. Available outer diameter options: 48.3mm and 60.3mm; wall thickness options:3.2mm,3.5mm,4.0mm. Featuring 8-hole rosette connection design, the pipe enables rapid bolt-free assembly, high structural rigidity and excellent wind resistance. Widely used for high-rise building facades, bridge construction, heavy shoring and complex industrial scaffolding projects, popular among large construction contractors and scaffolding rental companies.
