REBAR BOLTS

It is a corrugated steel bar for concrete reinforcement, with one end threaded to a length of 150-200 mm to install a nut with an anchoring plate, and the other end cut at a 45-degree angle for insertion into the hole. It consists of a main body with a series of longitudinal grooves (corrugations) that increase its anchoring capacity in the surrounding rock.

The 45-degree cut inner end facilitates its insertion, and the threaded outer end tensions the bolt and the plate using a nut, which can be hexagonal or round.

They can be mounted with resin cartridges or cement mortar.
