Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
