outside shading system This system mainly used for in summer shading ,let light diffusion enter greenhouse,ensure crops prevent strong light burnt,because proof big lots amount lights enter,so high efficient proof inside greenhouse heat accumualtion. Anti-UV,anti-hail,reduce the greenhouse top damage by feed different crop,choose differents shadign curtain so satisfy different crop for sunlight different need shading and reduce temperature:summer by close curtains can effective reflection some sunlight,can let temperature reduce 4 degree-6degree product description: speed reducer by drive shaft carry A type gear round,gear carry rach do line reciprocation because rach connect with pull rod togetherpull rod also connect with active profilesso carry shading curtain realize expandclose etc reaction.The shading mesh move in tunnels between support curtain line and pressure curtain line .
