LENTON® Fortress is a shear reinforcement system that is custom made to meet specific application needs. Made from 500MPa, LENTON® Fortress is a continuous flat steel strip that has holes punched along its center and is pre-bent into a custom-shaped profile to fit over the top of the flexural reinforcement bars in the concrete slab. Ideal for column/floor intersection and flat slab construction, LENTON® Fortress is quick and easy to install after rebar placement.
