Roll Threaded Adjustable STEEL PROPS
Manufacture scaffolding and formwork that is safe, reliable and built to last.
Roll Threaded Adjustable STEEL PROPS
These are made of 40 mm NB inner pipe which moves telescopically in the outer pipe of 50 mm NB.
The tubes conform to IS :
1161, YST 210 Grade of medium class. Outer 60.3 mm OD and Inner 48.3 mm OD. Beyond 3.6 m height, inner tube is to be braced in both directions after the threaded end of outer tube by Double Couplers. Heavy Duty Cast Iron malleable Nuts are used. They are available in Stirrup Head, Flat plates or Beam head. Beam head is a separate attachment.

Roll Threaded Outers
Roll Threaded outer is a recent innovation in scaffolding industry. Which has replace cut-thread process. In rolled threading method excess material is pressed in the pipe thus preventing wastage of material. There by increasing its load taking capacity. These are made from 50NB tubes of special grade as per IS standards.
