IN ORDER TO DETERMINE CLEAR OPENING HEIGHT, DEDUCT THE APPROPRIATE BOX SIZE TOGETHER WITH THE BOTTOM RAIL HEIGHT FROM THE OVERALL SHUTTER HEIGHT. SO FOR AN OVERALL SHUTTER HEIGHT OF 2000mm, CLEAR OPENING WILL BE 2000mm - 300mm - 68mm = 1632mm

FOR CLEAR WIDTH ON MANUALLY OPERATED SHUTTERS, DEDUCT APPROPRIATE GUIDE WIDTH AND THICKNESS OF FIXING ANGLES. SO FOR AN OVERALL WIDTH OF 2000mm, CLEAR OPENING IS 2000mm - 100mm (2 x 50mm) - 6mm (2 x 3mm) = 1894mm.

WHEN ATTEMPTING TO CALCULATE CLEAR OPENING WIDTHS ON ELECTRICALLY OPERATED SHUTTERS, IT IS IMPORTANT TO RECOGNISE THAT FACTORS OTHER THAN THE SIMPLE GUIDE WIDTH COME INTO PLAY. THE GUIDE TO THE MOTOR SIDE IS SPACED OFF THE FIXING ANGLE BY 30mm TO FACILITATE ACCESS TO THE MOTOR LIMITS AND OVERRIDE IF PRESENT AND WHEN THE MOTOR IS ABOVE 120Nm, THE SPACING IS INCREASED TO 50mm.

FURTHERMORE, IF AN ANTI-DROP BRAKE IS FITTED, THE OPPOSITE GUIDE WILL ALSO BE SPACED OFF ITS FIXING ANGLE. WHEN THE WEIGHT OF THE CURTAIN IS BELOW 150kgs A 30mm SPACING IS REQUIRED, AND WHEN ABOVE 150kgs A 50mm SPACING IS USED.

IF IT IS IMPORTANT TO KNOW THE CLEAR OPENING WIDTH OF ONE OF OUR ELECTRICALLY OPERATED SHUTTERS, PLEASE CONTACT US AT VBS UK AND WE WILL PROVIDE YOU WITH AN ACCURATE DIMENSION.

Traditional Commercial Security Shutters

 

Traditional commercial security shutter construction employs galvanised steel channel and angle guide with electric or manual operation. Our SS75T (solid lath) or SV75T (perforated lath) security shutters are compliant with the latest European product directives and standards, including BSEN 13241-1. Used for higher levels of security on commercial or retail properties.

 

Please note that ALL exposed steel parts are fully galvanised. We DO NOT use oxide paints on shutter angles and endplates as is commonplace on many cheaper products.

 

Specifics:

Fixing angles: 3mm galvanised steel 75 x 50mm, drilled for bolting to guides with M8 Nyloc nuts and bolts. 6mm angle will be used for electric shutters with curtains above 144kgs in weight

Head plates: 3mm galvanised steel with a 45º chamfer to the lower leading edge

Guide channel: 3mm galvanised steel. 50 x 32mm standard to manual operation. 65 x 32mm standard to electric operation. May be upgraded to Windlock guide channel for even higher security (recommended when using the stronger 20swg shutter lath).

Curtain: Either 75mm x 22swg or 75mm X 20swg scrolled galvanised steel lath, in either solid or perforated format, attached to axle with 400mm attachment strips 250mm from each end and then at every 500mm with M8 bolts.

Axle: Corrosion treated axle, diameter to suit width and curtain weight.

Hood: 1mm sheet steel hood, fully galvanised, with a 45º chamfer to the lower leading edge.

Finish: Galvanised as stated but optional powder coating in RAL or BS colours is available at a surcharge (click here to see our stocked powder colours) and almost any RAL or BS colour can be accommodated.

Minimum width: 1000mm

Maximum width x Height: for 22swg guage, electric - 6000mm x 4800mm; manual - 4000mm x 2800mm and for 20swg guage, 7000mm X 5000mm electric only  

Maximum area: electric - for 22swg guage  20 sq. m. and for 20swg guage 28 sq. m. ; manual - 8 sq. m. (22swg guage only)

Bottom rail: L-section 68mm high x 31mm deep; T-section 68mm high x 74mm deep

Box sizes: shutter height up to 1199mm - 250mm box

                 1200mm to 2499mm - 300mm box

                 2500mm to 3399mm - 350mm box

                 3400mm to 4700mm - 400mm box
