Introduction

Bar Flex is a Grade 304 austenitic stainless steel reinforcing material that has many unique properties. Being rolled from a plain round wire the fins are work hardened to a very high level whilst the core remains relatively soft. The subsequent tensioned, free-twisting process places the hardened fins in tension and the soft core into compression. The tensile strength of the base material is more than doubled during the manufacturing process. The deformation of the fins makes the bonding characteristics of the Bar Flex, far superior to alternative standard reinforcing materials.
