Swellex rock bolts

In most cases, TITANEX bolts are designed for temporary support for 2-3 years. So no special surface treatment is needed. However, when a longer service life is required, the zinc-galvanized steel pipe is selected because it has a rust-preventing ability comparable to that of stainless steel, and is less expensive.

Dimensions and models of expansion friction bolts:

TITANEX 12 - Diameter: 27.5mm~41mm, t: 2.3mm Breaking load: 120kN

TITANEX 16 - Diameter: 36.0mm~54mm, t: 2.3mm Breaking load: 160kN

TITANEX 24 - Diameter: 36.0mm~54mm, t: 3.0mm Breaking load: 240kN
