Heavy Duty Shutter in UAE

The shutter curtain is made of 75mm or 100mm pitch and 17mm wide superior single skin zincalume steel slats, with thicknesses ranging from 0.8mm to 1.2mm. These slats are manufactured by a roll forming process and constructed of reinforced interlocking slat profiles. The edges of the slats are auto cut-off to (end)lock the axial movement of the interlocked curtains, providing maximum strength and integrity. For external applications, the shutters can withstand a 40 km/h wind speed, with wind locks as optional reinforcement.

Side guides

For exposed and face fixing applications, ‘G’ shaped guides made of heavy duty 75mm wide x 100mm deep x 1.5mm thick galvanized steel is used. For concealed guide application, 75mm wide x 75mm deep x 1.5mm thick ‘U’ shaped galvanized steel guides are used.

Bottom bar

The leading slat is roll formed from zincalume steel with a thickness equivalent to that of the slat. Two 38mm x 38mm x 3mm or 50mm x 50mm x 5mm thick galvanized steel angle bars are bolted to the leading slat to form the bottom bar. The bottom bar can be provided with a EPDM weatherseal strip to provide required weather resistance.

Shutter box

The shutter box is made out of two heavy duty steel endplates of thickness 4mm to 7mm according to the size of the shutter; joined together using five steel hollow sections of 50mm x 25mm, primer finished in black. Two 50mm x 50mm x 4.5mm thick steel angles with slotted fixing holes are welded with the end plates to fix the shutter box to the building structure.

Barrel

The barrel is made of a heavy duty seamless steel pipe, welded with axles of dia 35mm to dia 50mm according to the size of the shutter. This barrel is fixed to the right and left endplates with heavy duty sealed roller bearings.

Box Cover

The shutter box covers are made out of 0.8mm thick zincalume steel sheets, with the edges folded to provide rigidity.
