Roll-formed GI steel reinforcement channels — U, C, square/box and custom sections — matched to your uPVC profile series and supplied in bulk to window fabricators and profile distributors.

Overview
Steel reinforcement is what keeps a uPVC frame straight under wind load, hardware load and heat. We roll-form galvanised steel channels to the exact chamber dimensions of your profile series, cut to length and bundled for your shop floor.
Few manufacturers sell reinforcement to other fabricators. We do — consistent dimensions, controlled zinc coating and dependable bulk supply for uPVC fabricators and profile distributors across India.
Sections matched to the chamber of each profile series you fabricate.
Galvanised coil with specified GSM for corrosion protection.
Tight dimensional tolerance so reinforcement slides in cleanly.
