The top is covered with Po film or crystal film,and the surrounding is covered with Po film . Multi-span greenhouses have the advantages of rapid temperature increase, cost-effective, and high light transmittance. The design adheres to the rationality and advanced nature of the greenhouse configuration, adapts to local conditions, combines the local greenhouse climate conditions, uses and needs, and reasonably selects supporting equipment.

The polycarbonate (PC) greenhouse is preferred Venlo type (also can use circular arch type), using a multi span roof, with shape of modern, stable structure, beautiful form, smooth version, remarkable thermal insulation performance, moderate light transmission rate, many rainy grooves, large span, drainage volume, strong wind resistance ability, suitable for area of big wind and rainfall.

The Glass Greenhouse is characterized by high light-transmitting rate,beautiful appearance, simple construction and stable structure, suitable for the plants of great demands for sunlight.The design is with 3 roofs and double slopes every span.
