Griptec, Bartec/Fortec, Rolltec Carbon Lite couplers

Dextra’s Carbon Lite coupler range (Griptec®, Bartec®/Fortec®, and Rolltec®) is a full performance mechanical splicing system for concrete reinforcing bars with diameters from Ø12 to Ø50 mm, manufactured using EAF produced steel with high recycled content, without affecting its mechanical performance. The mechanical performance of the Carbon Lite couplers is verified through testing in accordance with internationally recognized standards for mechanical reinforcement couplers, including applicable ISO, European, national, and industry standards (e.g. ISO 15835‑1 and equivalent regional standards). Declared performance characteristics include static tensile strength, slip or permanent elongation, ductility, cyclic and fatigue behaviour, and bar‑break performance, ensuring suitability for structural applications in reinforced concrete construction.
