Performance and Key Applications

The Gliderol Alfresco Steel Outdoor Roller Shutter combines security, ventilation, and durability in a single system, making it ideal for commercial and residential openings where airflow and visibility are important.

Opening suitability: Ideal for commercial or residential openings up to 3.5 m wide × 3 m high in a single panel.
Larger openings: The Alfresco Steel Outdoor Roller Shutter is recommended to be motorised for ease of operation.
Curtain material: Employs the same design principles and components as the Roller Door, except for the curtain material, which consists of 75mm x 0.8mm thick galvanised steel interlocking slats.
Ventilation design: The entire concave portion of these slats contains 3.3mm diameter perforations spaced at 4.9mm staggered pitch, which gives excellent airflow through a total perforated surface area of approximately 40.5%.
See-through effect: Allows visibility while preventing debris or cigarette butts from entering the premises.
Structural integrity: The scroll edges of the slats are not perforated to avoid weakening the interlocking joints.
Powder-coated finish: 'Alfresco' shutters are recommended to be powder-coated because the coating thickness adequately covers the burrs of the perforated edges, smoothening out any sharp edges. Powder coating also offers greater flexibility in colour choice, an advantage greatly appreciated by most of today's Architects.

Technical Features and Build

Our Alfresco Outdoor Roller Shutter is architecturally specified as a manually operated Roller Shutter constructed of 75 x 0.8 mm thick galvanised steel interlocking slats in powder-coated finish, with approximately 40.5% of the concave surface perforated to achieve a 'see-through' effect with good airflow.

Scroll Edges and Clips

The scroll edges where the slats interlock must not be perforated. The drum assembly shall consist of a rigid corrugated torque-tube containing suitably graded oil-tempered torsion springs secured to nylon drumwheels.

The edges of the slats shall be fitted with proprietary nylon end-clips secured to alternate slats to prevent lateral movement of the slats.

Bottom Rail

The bottom rail shall consist of a single-length aluminium extrusion with the base of the rail containing two slots to retain a seamless finned PVC weatherseal.

Guides

The outdoor roller shutter guides shall also be a proprietary extruded aluminium section with slots at the lips to retain a seamless PVC strip designed to prevent metal-to-metal contact for smoother and quieter operation.

Consequently, the guide channels shall not require initial and periodic greasing to aid door operation.

Control Box and System

Electrically operated doors shall be as above described, but containing a proprietary motor operator installed within the door roll.

The control box shall feature push-button controls and a built-in auto-stop safety device.

The system must be convertible to manual operation at arm's reach and have remote control and power back-up capabilities.

Note: Any desired special operating requirements should be specifically stated. A manufacturer's warranty certificate with the desired warranty period should be obtained.
