75mm All-Steel PVC Hinge
75mm PVC steel hinges are high-strength functional accessories manufactured entirely from sheet steel with zero breakage risk, designed to bear the full load of opening sashes in plastic door and window profile systems. Containing no plastic injection casing or zinc die-cast components whatsoever, these fully press-formed solid metal hinges resist deflection even under heavy double and triple-glazed combinations. They permanently eliminate chronic PVC window problems such as sash sag, wind-load rattle and lock axis misalignment. Stamped from quality steel sheet on our high-tonnage eccentric press and precision tooling lines, 75mm solid steel hinges operate silently and without wear for years thanks to their strong pin structure and anti-corrosion coating.
- Material Construction: Fully press-formed steel body with maximum resistance to breakage, cracking and bending — contains no plastic or zinc components.
- Corrosion Protection: First-class hot-dip galvanised, zinc or electrostatic powder-coat finish options providing lifetime resistance to outdoor conditions, moisture and condensation.
- Dimensions and Fixing: 75mm standard body length; countersunk screw-hole axes suitable for direct screwing to the internal profile reinforcement steel.
- Applications: Heavy-duty PVC single-action and casement window sashes, PVC balcony doors, fly-screen systems, and site-type temporary door/partition frames.
