anti-theft steel door/steel security door/roller shutter garage door

Product advantages

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.
