Steel-Reinforced Plastic PVC Hinge
Steel-reinforced plastic hinges safely attach opening sashes to the frame in PVC door and window profile systems, combining aesthetics and strength in one product. The outer first-class plastic injection body creates a seamless visual match with PVC profiles, while the concealed internal steel reinforcement maximises load capacity. This hybrid construction combines the lightness and rust-free benefits of plastic hinges with the unbending strength of steel, permanently preventing chronic problems such as sash sag and loosening. Steel-reinforced PVC hinges manufactured by Hira Metal on precision injection and pressing lines feature accurate pin bearings and smooth surface quality, operating silently and comfortably for years.
