SHUTTER CURTAIN AND GUIDES
SINGLE SKIN CURTAIN SLAT
The shutter curtain is made of 75mm pitch superior single skin Galvanized steel slats, with 1.2mm thickness. 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.
GUIDE RAILS
For exposed and face fixing applications, ‘G’ shaped guides made of heavy duty 75mm wide x 100mm deep x 3mm 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 Galvanized steel with a thickness equivalent to that of the slat. Two 50mm x 50mm x 3.7mm thick Galvanized steel angle bar are bolted to the leading slat to form the bottom bar.
