Product Overview

Galvanized Scaffolding Pipe is a hot-dip galvanized carbon steel tube designed for construction scaffolding, temporary support systems, and access structures. With a standardized outer diameter of 48.3mm (1-1/2 inch NPS, DN40), it provides a reliable tubular solution for building contractors, scaffolding rental companies, and engineering construction projects.

Manufactured according to BS EN39, BS1139, GB/T13793 and JGJ130 standards, the product is available in multiple steel grades including Q235B, EN39 S235GT, BS1139 St44 and S235JR to meet different construction requirements and international project specifications.

The scaffolding pipe supports multiple wall thickness options including 3.0mm, 3.2mm, 3.5mm and 4.0mm, allowing customers to select suitable solutions for light-duty, standard construction and heavy-load scaffolding applications. Standard length is 6 meters, with customized cutting from 1 meter up to 12 meters available.

Only hot-dip galvanizing (HDG) treatment is applied for scaffolding applications. With zinc coating weight ≥200g/m², the pipe provides corrosion resistance for outdoor construction environments and is widely used in facade scaffolding, ring-lock scaffolding, stage structures, storage racks, ship maintenance platforms and temporary engineering structures.
