90mm Heavy-Duty All-Steel PVC Hinge
90mm PVC steel hinges are heavy-duty accessories designed to carry the load of wide and heavy opening sashes in plastic door and window profile systems, manufactured entirely from sheet steel with zero breakage risk. Containing no plastic injection casing or zinc die-cast components, these long-body 90mm hinges resist deflection even under the heaviest double/triple comfort glazing combinations. They permanently eliminate chronic PVC joinery problems: door/window sag, lock axis misalignment and wind-load deformation. Stamped from quality steel sheet on high-tonnage eccentric press lines, 90mm steel hinges operate silently and without wear even in high-traffic doors thanks to their reinforced extended pin structure and anti-corrosion coating.
- Material Construction: Fully press-formed steel body with maximum resistance to snapping, cracking and breakage — no plastic or zinc components.
- Corrosion Protection: First-class hot-dip galvanised, zinc or electrostatic powder-coat finish for high resistance against outdoor conditions, moisture and condensation.
- Dimensions and Fixing: Extended 90mm standard body design; countersunk screw-hole axes for direct screwing to the internal profile reinforcement (inertia) steel.
- Applications: Heavy-duty PVC door and balcony sashes, large-span PVC windows, fly-screen systems, and site/office partition frames.
Why Hira Metal?
- Direct Factory Wholesale: As a manufacturer, the most competitive wholesale steel hinge prices for high-volume box/carton orders, PVC joinery workshops and hardware dealers.
- Zero Breakage and Maximum Load Capacity: Will not break or crack under sudden stress or heavy impact; the high flexibility and hardness balance of steel safely carries the heaviest sash loads.
- Installation-Error-Prevention Tooling: Millimetre-parallel pin bearing and screw axes prevent profile jamming during installation, maximising assembly speed and saving time.
