Product Overview​

Our Multi-Span Plastic Film Greenhouse is engineered for medium to large-scale agricultural operations, offering a continuous, expansive growing space to maximize productivity. By connecting multiple single spans into a unified structure, it eliminates isolated growing areas, enabling efficient mechanized management and large-volume crop production. Ideal for commercial vegetable farms, flower plantations, and nursery operations, this greenhouse balances cost-effectiveness with durability, creating a controlled environment to boost yields and extend growing seasons across hectares of land.​

Core Features​

Robust Structural Design​
Frame: Heavy-duty hot-dip galvanized steel trusses (40-60mm diameter, 2.0-3.0mm thickness) with anti-corrosion treatment. The multi-span structure distributes loads evenly, withstanding wind speeds up to 0.45kN/m² and snow loads up to 0.5kN/m²—suitable for most climatic zones.​
Longevity: Galvanized frame lifespan 15+ years; connections reinforced with high-tensile bolts to prevent loosening under repeated weather stress.
​
High-Performance Plastic Film System​
Cover Material: 150-200μm UV-stabilized PE film with 85% light transmission, optimized for photosynthesis. Anti-condensation coating reduces moisture buildup, lowering disease risks. Film service life: 3-5 years.​
Installation: Film secured with aluminum clips and tensioning systems to prevent sagging or tearing, even in strong winds. Optional double-layer film (with air gap) enhances insulation by 30% for cold regions.
​
Expansive & Customizable Layout​
Dimensions: Standard spans 6-12m per unit, total width 30-100m+; side height 2.8-4.0m, length 50-200m+. Customizable to fit land contours and production needs.​
Space Efficiency: No internal support columns, maximizing usable area for mechanized equipment (tractors, harvesters) and vertical growing systems.
​
Advanced Ventilation & Climate Control​
Roof Vents: Motorized roof vents (25% total area) with temperature/humidity sensors for automated airflow, preventing heat buildup in summer.​
Side Vents: Roll-up side curtains (2.0m height) with gear-driven mechanisms for cross-ventilation, regulating internal temperatures (15-30°C) year-round.​
Compatibility: Integrates with heating systems, CO₂ enrichment, and drip irrigation for a fully controlled growing environment.
