Specifications of  sectional garage door

Garage roller shutter/ commercial roller shutter door are medium-sized rolling shutters

used at housings like villa, high-end residence, and at public places, especially when

it is  linconvenient to install doors on ground., making it simpler and quiker.

1,Anti-liftup, property security protection  

    Anti-liftup system brings tamper resistance to ensure safety of indoor car and property.

 2, Well-lighted slat, keeping indoor ventilation and light softened  

    Several slats with holes are added to at upper position of shutter to let light and air enter,

    to keep indoor environment refreshing.

 3, Super-strengthened steel slat, high-density foam---better performance, thermal insulation,

     energy conservation and environmental protection  

    The slat is made out of highly strengthened steel, filling with imported high-density

    polyurethane foam, with surface scratch-resistant through polyester painting and

    roll coating, which keeps it from color-fading, brings abrasion-resistance, thermal

    insulation, noise insulation, better corrosion resistance, maintains indoor temperature

    and saves energy consumption.

Rolling surport system  

  It reduces friction between slat and guide rail, so that slats run more smoothly and service life is

  prolonged. When shutter is shut, slats are more adapted to guide rail to achieve better sealing effect.

 4,System Security- a variety of schemes for contingent power cut and when obstruction get in the way  

   Obstruction-encounter automatic stop system enables shutter stop lowering immediately when

   some obstruction gets in the way, avoiding slats are unhooked and damaged when shutter starts

   reverse running direction, which prolongs service lift of roller shutter.  Obstruction-encounter

  automatic direction reverse system enables shutter stop lowering and convert it running in reverse

  direction  to let person or object pass through safely.   Manual operation with crank handle is reserved

  to make it work normally when power is off.
