Manual Chain Operated Roller Shutter Doors

Security Features

•    Single Skin Scrolled Steel Slat: Available in solid, punched (vision), or perforated designs to suit visibility and airflow requirements.
•   Robust Construction: Traditional-style steel roller shutter with a scrolled slat profile ensures strength and reliability for medium-security applications.
•   Shoot Bolts (Optional): Can be added to guide rails for extra security on manual shutters.
•   Bullet Locks Available: Optional bullet locks can be fitted for enhanced manual security
   

Safety Features

•    Counterbalance Spring System: Ensures controlled, smooth raising and lowering of the shutter via the manual chain mechanism.
•   Spring Load Adjustment: Final adjustment of spring loading is done post-installation for optimal safety and function.
•   Installation Versatility: Can be fitted both internally and externally, offering flexible safety placement depending on the building structure
   

Insulation & Energy Efficiency

•    Steel Laths: While focused on strength, the 75c offers basic environmental separation; however, it is not primarily insulated.
•   Slat Options:
  •       22g Solid Steel: 10 kg/m²
  •       20g Solid Steel: 12 kg/m²
  •       Vision Slats: 8 kg/m²
  •       These weights and densities provide a basic barrier against airflow, contributing to reduced draughts in closed conditions
