This standard specifies the requirements for steel tubes and fittings used in scaffolding, covering material properties, dimensional tolerances, and mechanical tests to ensure stability and safety of temporary structures during construction.

Specifies requirements for materials, dimensions, and construction of steel scaffoldings.

Quick Reference Values
Standard Outside Diameter (OD)48.3 mm
Standard Wall Thickness4.0 mm
Nominal Mass of Tube4.37 kg/m
Tolerance on Outside Diameter+0.4 mm, -0.8 mm
Maximum Permissible Deviation in Mass+10 percent, -8 percent
Practical Notes
Ensure scaffolding tubes conform to the exact 48.3 mm outer diameter for safe grip and compatibility with standard couplers.
Wall thickness reduction due to wear and corrosion must be monitored periodically; heavily rusted or deformed tubes should be discarded immediately.
This code acts as a material specification; for safe erection and dismantling practices, always refer to IS 3696 (Part 1).
