uPVC Window Steel Reinforcement

Strength Behind
Every uPVC System

Total Steels manufactures precision cold-formed steel reinforcement profiles designed to fit inside uPVC window and door frames. These profiles provide the structural backbone that allows uPVC windows to withstand high wind pressures, heavy loads, and large span installations without warping or deformation.

Our reinforcement sections are manufactured to exceptional dimensional accuracy with tight tolerances — engineered to fit uPVC profile systems across all major window and door manufacturers. Available in OSLC, Box, C Channel, Step Channel, Open Lip, and Grove Channel configurations.
