ROLL-A-DOOR CURTAIN DESIGN
ROLL-A-DOOR curtain are fabricated from first grade high tensile zinacalume, galvanized or coloring steel from BFJ. Curtains shall be continuous sheet design with roll formed LOCKSEAM permanently locked together to form a rigid single panel. Both sides of the door panel will be fitted with durable, frictionless NYLOFELT to ensure smooth operation of the door curtain, with a life span of 18.000 cycles. Mini groove design at the top of curtain is provided to give needle & barrel supped when the door is fully closed. Curtain sheet is a precision pressed groove design to achieve strength & rigidity of the door panel.
DRUMS will be made of high quality steel, pressed form design with grooving to lock the curtain to the drum ensuing god's of the curtain & drums. AII ROLLER DRUMS will have a nylon sleeve to ensure long lasting operation. ROLL-A-DOOR drums are designed to be untraceable to operate by chain, Planetary Gearing System or motorized.
Side guide all be of first grade galvanised steel with a minimum wall thickness of 2.0mm, Incorporating an end clip design & fitted with a rigid stopper, including rubber cushion. The guide depth of SERIES 1 & 2 curtain is 30mm & 50mm respectively.
SAFETY DIE-CAST LOCKSET
Superior tamper proof waist high inset with DIE-CAST by & face plate with chrome finish. Dual mode operation with outside key & inside knob design. All locksets are provided with horizontal lock horn supported by secure guide block.
PRECISION SPRINGING SYSTEM
AL RLL-A-DOOR have incorporated high tensile carbon s spring combinations with precision adjustment to allow the ROLL-A-DOOR to achieve a balance at any position. With ROLL-ADOOR precision springing technology operating, the door should require no greater than 10kgf to lift up the door.
ROLL-A-DOOR manual operation by precision springing balance system will enable the door to maintain its balance at any position. For door height above 4500mm an option to have chain or planetary gear assisted for easy operation.
All ROLL-A-DOOR motor drive system are complete with auto reverse design safety edge.
