China Tunnel Film Greenhouse

The China Tunnel Film Greenhouse is a modern agricultural structure that combines a hot‑dip galvanized steel frame with a high‑transparency film covering. The steel tubes are zinc‑coated at 275 g/m², providing a service life of over 20 years and resistance to wind loads of 0.4 kN/m² and snow loads of 0.3 kN/m². The covering film offers high light transmittance, good insulation, and aging resistance, with a typical service life of 5‑7 years. Standard dimensions include a span width of 6‑8 m, column spacing of 4 m, and shoulder height of 2‑3 m, while custom sizes are available. Integrated systems such as top window ventilation, fan and wet‑curtain cooling, external and internal shading, thermal insulation, seedbed, light‑filling, and heating enhance climate control. Optional intelligent modules add sun‑shading nets, automated heating, irrigation, hydroponics, photovoltaic power, and full automatic control. The greenhouse is suitable for year‑round cultivation of vegetables, flowers, medicinal plants and cash crops, offering cost‑effective construction and low maintenance. Its modular design allows scalability from small home gardens to large commercial farms, with turnkey design services provided by the manufacturer.
