PVC Punched Mullion Connector Bracket
PVC punched mullion connector brackets are high-strength connectors that allow vertical and horizontal mullion (T-profile) profiles in plastic door and window joinery systems to be screwed to the main frame without vibration, deflection or misalignment. Special punch tabs in the body design prevent the bracket from sliding inside the plastic profile during screwing. This punch system permanently prevents the mullion profile from sagging, rotating or opening at joints after installation due to heavy glazing loads or outdoor wind pressure. PVC punched connector brackets manufactured from hardened metal sheet on precision tooling at Hira Metal lock directly to the profile reinforcement steel, offering weld-quality rigidity and extending window service life.
- Connection Technology: Special punch-pin design that grips firmly to the PVC profile inner wall and reinforcement steel, preventing sliding and rattle.
- Material Construction: Hardened sheet metal with first-class galvanised coating, resistant to corrosion, moisture and condensation.
- Installation Advantage: Millimetre-precision body seats flush in PVC profile channels, minimising installer errors and reducing assembly time.
- Applications: PVC single-action, casement and sliding window systems, PVC balcony doors and lockable room door fabrication.
