PVC Sheet Metal Mullion Connector
PVC sheet metal mullion connectors are high-strength assembly elements that allow vertical and horizontal mullion (T-profile) profiles in plastic door and window profile systems to be screwed to the main frame without vibration, deflection or misalignment. Designed to perfectly match the internal geometry of PVC profiles and the internal reinforcement steel (inertia steel), these metal brackets maximise window resistance to wind load, deflection and heavy glazing weight. Manufactured from hardened sheet metal on precision tooling and high-tonnage press lines at Hira Metal, they do not deflect, crack or jam in the plastic profile during installation, giving fabricators high speed and ease of assembly.
- Material Construction: Hardened sheet steel with first-class galvanised or electrostatic-painted coating for lifetime resistance to condensation, moisture and corrosion inside PVC profiles.
- Mechanical Locking: Optimised hole axes screwed directly to the profile reinforcement steel permanently prevent screw loosening and mullion sagging.
- Installation Advantage: Millimetre-precision body seats flush in standard PVC profile channels, minimising installer errors.
- Applications: PVC single-action and casement window systems, PVC balcony doors, conservatory partitions and lockable room door fabrication.
Why Hira Metal?
- Direct Factory Wholesale: As a manufacturer, the most competitive wholesale pricing for high-volume box/carton orders, PVC joinery workshops and hardware dealers.
- Anti-Sag and Anti-Deflection Construction: Prevents axis misalignment from long-term deflection; ensures corner and mullion joint seals are fully compressed, maintaining wind, air and water tightness.
- 100% Standard Tooling: Perfect compatibility with the inner cavities of popular PVC profile brands (60mm, 70mm, 80mm series) in the market.
