The Single Span Tunnel Greenhouse is an arch-shaped, film-covered growing structure engineered for commercial nursery operations and vegetable farming. Featuring a hot-dip galvanized steel frame with zinc coating reaching 200 to 275 grams per square meter and covered with 150-micron UV-resistant anti-drip PE plastic film, this single span greenhouse delivers outstanding resistance against strong winds and heavy snow loads. The arch shape design provides superior structural integrity while maximizing internal growing space for efficient crop production. Polyethylene film covers approximately 95% of the world's commercial greenhouses, making this single span tunnel greenhouse the most widely adopted solution in the global horticulture industry.
• Arch Shape Structural Design – The curved arch configuration distributes wind and snow loads evenly across the structure, providing superior strength-to-weight ratio. This single span greenhouse design maximizes interior headroom and growing space compared to traditional peaked structures.
• Hot-Dip Galvanized Steel Frame – The 200–275 g/m² zinc coating delivers 10x rust resistance compared to standard galvanized steel, ensuring 15–20 years of structural integrity even in coastal or high-humidity environments where nursery operations are commonly located.
• UV-Resistant Anti-Drip PE Film – The 150-micron cover features UV stabilization and anti-drip technology, preventing condensation damage to young seedlings and nursery stock while blocking harmful UV rays. Light transmission reaches 85–87% for optimal photosynthesis.
• Tool-Free Modular Assembly – Pre-cut components with bolted connections and steel clips eliminate on-site welding, enabling 50% faster installation than traditional welded structures. This single span greenhouse can be assembled by farm workers without specialized training.
• Superior Weather Performance – Engineered to withstand wind speeds up to 120 km/h and snow loads up to 25 kg/m², ensuring reliable crop protection across diverse climate conditions from tropical to temperate zones.
• 5-Year Anti-UV Warranty & Factory Direct Pricing – The PE film is guaranteed against UV degradation for five years, while factory-direct pricing eliminates intermediary costs, delivering exceptional value for commercial nursery and farming operations.
The single span tunnel greenhouse is suitable for a wide range of commercial cultivation applications:
Nursery Operations – This single span greenhouse creates an optimal environment for seedling propagation and young plant production. The controlled conditions enable consistent germination rates and healthy transplant development, with the arch design providing ample headroom for nursery stock of varying heights.
Tomato Production – The single span greenhouse creates an optimal microclimate for tomato cultivation, with UV-transparent film enhancing fruit quality and yield. Early yields can reach up to 30% higher than conventional cultivation methods.
Pepper and Strawberry Cultivation – The controlled environment protects high-value cash crops from extreme weather while the anti-drip film prevents moisture-related diseases that commonly affect peppers and strawberries.
Leafy Greens and Herbs – This single span greenhouse supports year-round production of lettuce, spinach, basil, and other high-demand leafy greens, extending growing seasons in both temperate and tropical regions.
Flower and Ornamental Production – The single span tunnel greenhouse provides ideal conditions for cut flowers and ornamental plant cultivation, with light diffusion properties that reduce plant stress from direct sunlight.
Our single span tunnel greenhouse delivers distinct advantages over conventional cultivation methods and competing products. Compared to glass or polycarbonate greenhouses, our PE film single span greenhouse offers significantly lower initial investment while maintaining exceptional functional performance. The arch shape design provides superior weather resistance at a lower material cost than peaked structures. The tool-free assembly reduces labor costs and installation time, while factory-direct pricing eliminates intermediary markups.

Whether you need a single span greenhouse for a small nursery or multiple units for large commercial farming operations, we provide consistent quality and responsive service.
Q: What is the lifespan of different types of greenhouses?
A: Up to 3-5 years for film, 20+ years for glass and polycarbonate greenhouses. Film covers require replacement every 3-5 years, while the galvanized steel frame lasts over 20 years. Glass and PC panels offer longer service life with minimal maintenance, making them ideal for permanent installations. Our greenhouse frames use hot-dip galvanized steel pipes with a double-sided zinc coating of 200-275 g/m², providing uniform, dense, and strongly adherent protection specifically engineered for high-humidity greenhouse environments and long-term corrosion resistance.
Q: How long does it take to install a commercial greenhouse?
A: Installation typically takes 2-4 weeks depending on project size and complexity. Standard multi-span greenhouses can be erected in 10-20 working days by our experienced technical team at Ziyang Bozong. On-site assembly time varies based on local conditions and project scale, but we provide detailed installation manuals and remote guidance to streamline the process.
Q: Can you customize greenhouse specifications for my farm?
A: Yes, we offer full customization including dimensions, span width, height, covering materials, and ventilation systems. Simply share your crop type, local climate conditions, and growing area requirements, and our engineering team at Ziyang Bozong will design a tailored solution that optimizes your growing environment and maximizes ROI.
Q: What is your warranty policy for greenhouses?
A: Our galvanized steel frame comes with a 5-year warranty against corrosion and structural defects. Film covers include a 3-5 year UV warranty depending on the grade selected, while glass and PC panels are covered by manufacturer warranties. Ziyang Bozong provides technical support and replacement parts throughout the lifespan of your greenhouse.
Q: How do I choose between film, glass, and PC greenhouses?
A: Film is best for budget-conscious projects with 3-5 year cycles; glass offers the longest lifespan and highest light transmission; PC provides excellent insulation and impact resistance. Our team at Ziyang Bozong can recommend the optimal material based on your local climate, crop requirements, and budget constraints to ensure the best long-term value for your farm.
Q: How often does the PE film need to be replaced?
A: PE film typically needs replacement every 3-5 years depending on UV exposure and climate conditions. Our multi-layer co-extruded PE film is engineered with UV stabilizers and anti-drip coatings to maximize lifespan. Ziyang Bozong offers replacement film in various thicknesses (150-200 microns) to match your specific growing requirements.
