Large Polyethylene Multi Span Greenhouse 200 Micron UV Resistant

Advantages

1. Galvanized Steel Frame, Stable and Corrosion-resistant
The greenhouse uses high-strength hot-dip galvanized steel pipes (with a zinc layer ≥275gsm). Its corrosion resistance is better than that of ordinary steel materials, and it can adapt to humid, acidic and alkaline environments. The service life is 10-15 years. The horizontal climbing rod at the shoulder and the suspension rod at the top form a triangular structure, enhancing the wind resistance (≤90km/h) and providing support for vine crops.
2. Low Cost, High Return, Easy to Start
By optimizing the steel pipes and covering materials, the construction cost is only 60%-70% of that of traditional greenhouses, suitable for small and medium-sized farmers' initial investment. The pre-assembled accessories allow 2-3 people to complete the construction of a 100-square-meter single-unit greenhouse within 1-2 days (guided by the illustration). Without professional skills required, the snap connectors avoid welding and reduce the risk of rust and breakage. Standardized installation only requires bolt fixation.
3. Flexible Expansion, Adapt to Scale Changes
The standard single unit has a width of 8 meters (the length can be selected from 10-100 meters) and supports horizontal splicing to expand into a multi-span greenhouse, achieving a seamless upgrade from small-scale planting to large-scale production.
4. Efficient Drainage and Rainwater Recycling
The U-shaped galvanized drainage trough with a slope (2.5‰ - 5‰) increases the drainage efficiency by 40% and prevents waterlogging. The supporting rainwater collection system can save 20%-30% of water on average every year, suitable for water-scarce areas. EPDM sealing strips ensure long-term leakage prevention at the joints.
5. Multi-functional Covering Solutions
Agricultural Film: It is recommended to use a film with a thickness of 150-200 microns. The light transmittance is ≥90%, and it has functions of heat preservation and anti-ultraviolet.
Insect-proof Net: A 30-60 mesh nylon net is used for physical pest prevention, reducing the use of pesticides.
Sunshade Net: Silver aluminum foil/black sunshade net (shading rate 30%-80%) can reduce the temperature inside the shed by 5-8℃ in summer.
6. Natural Ventilation and Temperature Control
Manual rolling windows are installed on the top and around the greenhouse (with a window opening height of 2 meters), and are equipped with insect-proof nets to achieve efficient ventilation. Open the windows to cool down when it is hot, and close them at night to keep warm, taking into account energy conservation and the growth needs of crops.
