GP-827-S Multi-span Greenhouse is a substitute which replaces and is better than the older single composite steel plastic greenhouse.

The framework uses OD27x1.2mm or OD27mmx1.5mm composite steel plastic tube.In order to strengthen the greenhouse,posts are installed every 3 to 6 meters.The fittings use galvanized steel which is press formed.Some accessories are plastic sprayed to have high corrosion and rusting resistance.

The product uses a self-locked film-roller,and there is an manual control bi-direction film-roller along the gutter on the top.The covering surrounding the greenhouse is no-drip long-life film,and additional black sun-shading net is also available with a shading ratio of 60%-80%.2-layer shade,spraying equipment and high-effective energy-saving axis diversion fan are available to keep an ideal temperature and good ventilation.

Natural ventilation and forced ventilation can be chosen to lower the indoor temperature in summer.
