Galvanised Steel Roller Shutter Systems

A galvanised steel roller shutter is a motorised security closure in which galvanised steel slats coil around a barrel to seal an opening. Pack Door manufactures them to measure with 77, 97 and 115 mm slat options. They provide strong protection against burglary for shop, warehouse, factory and car park entrances, and are installed with a tubular or side motor, remote control and emergency release system.

Typical slat thickness ranges from 0.75 to 1.20 mm. For shops, 0.75–0.90 mm is usually sufficient, while warehouses, industrial sites and wide, wind-exposed openings call for 1.00–1.20 mm slats and an industrial motor. The correct thickness is determined during the site survey based on opening width, frequency of use and wind load; an intermediate post is added if required.

A galvanised steel roller shutter uses single-skin, high-strength slats that prioritise security and is preferred for shop and warehouse entrances. A polyurethane-filled roller shutter uses double-skin slats with a foam core, providing thermal and acoustic insulation and quieter operation. Polyurethane-filled shutters are recommended for heated spaces; galvanised steel is recommended where high security is required.

A single roller shutter is usually installed within one day, depending on site preparation. Made-to-measure production is scheduled after the site survey and approval; on installation day the guide rails, barrel, motor and controls are fitted, and the system is tested before handover. For multi-door projects, the schedule is confirmed after the survey to minimise operational disruption.

Roller shutter price depends on the opening size, slat type and thickness, motor torque, control and safety accessories, and colour choice. Because every shutter is made to measure, quotes are prepared per project. Once dimensions and a photo of the opening are shared, Pack Door responds within about one hour on average; a detailed itemised quote can follow a site survey if needed.

During a power cut, roller shutters with central or side motors can be opened by hand using the chain or crank manual override. If an optional battery backup unit is fitted, motorised operation continues throughout the outage. For tubular-motor shutters, a key-operated emergency release box is added for external access; the right method is chosen during the site survey according to the motor type.
