Rock bolts are manufactured from TMT grade special steel as per IS:8266/76 specifications in various types.

Expansion Shell Type

These bolts use expansion shells and plugs made of cast steel with left hand thread, firmly gripping the rock and the bolt forming anchorage. These are made of two types.
