When building a reinforced concrete strong room, it is essential to protect all walls against attempted break-in using heavy-duty tools such as oxyacetylene torches and powerful electric tools.


ELMI TWISTED BAR consists of twisted steel strips forming 3-dimensional reinforcement. When included in the concrete during the construction of the strong room, it provides just such highly effective protection.

Incontestable Advantages
Twisted Bar was specifically designed to resist break in and is an essential supplement to the conventional reinforcing steel used in concrete construction.


Its helicoidally form prevents break away of the reinforced concrete around it and thus maintains the overall strength.


A light-weight inexpensive solution
Its 3 dimensional form optimizes the protection provided by Twisted Bar.


A given weight of Twisted Bar will protect a far larger volume that the same weight of any conventional system: Twisted Bar weighs only approx 20 kg per square meter protected.


Tang Bar is compatible with any thickness of wall from 400mm to 1000mm. However, it must never be considered as a substitute for the normal reinforcing steel used in construction.
