Agricultural High Tunnel&Multi-Span Plastic Film Greenhouse

Have you encountered uncontrolled natural environment, poor structural design, inferior pipes, or film that cracks easily? Based on these real planting pain points, Huifa developed two standardized plastic greenhouse solutions: High Tunnel (single-span) and Multi-Span (gothic-arch connected) greenhouse.

Our film greenhouse series provides a stable growing environment that prevents rain, wind, pests, and diseases – suitable for Africa, Asia, Europe, and America. The high tunnel greenhouse features a scientific oval-pipe design (shoulder height 2m) for easy installation and wind resistance. The multi-span agricultural greenhouse offers larger internal space (shoulder height up to 5m) for mechanized farming.

Both types use all hot-dip galvanized components (275g/m²) and upgraded 3-layer PEP film (EVA + infrared absorber), ensuring 5-6 years film life and ≥15 years structure life. By choosing Huifa's standardized products + standardized delivery + mass production + rapid response, you reduce trial costs, accelerate ROI, and enjoy worry-free purchasing.

Product Advantages

Why Choose Huifa Greenhouse?

Huifa's plastic greenhouse series delivers the perfect balance of durability, ease of installation, and cost-effectiveness-backed by standardized production and rapid global support. Whether you need a high tunnel greenhouse or a multi-span agricultural greenhouse, our products are engineered for long service life and high ROI.

Stronger, Easier to Install-Spanish-style Multi-span & Gothic Arch

Our multi-span plastic greenhouse adopts a Spanish-style connected design, which simplifies on-site assembly and improves overall structural stability. The gothic greenhouse with a scientific oval-pipe design enhances wind resistance, making it ideal for variable climates. Together, they deliver a durable, farmer-friendly structure that reduces labor and installation time.

Long Use Life-PEP Film≥5years & Galvanized structure≥15years

Upgraded 3-layer PEP film (EVA + infrared absorber) is UV-stabilized, anti-drip, and tear-resistant, ensuring 150micron film for 5-6 years and 200micron film for 6-8 years used on film greenhouse. The hot-dip galvanized steel frame (275g/m²) resists corrosion and rust, ensuring the overall structure lasts 15 years or more. This dual-layer durability means fewer replacements and lower maintenance costs.

High Efficient & 0 Error-Standardized Products + Standardized Delivery

Every agricultural greenhouse from Huifa follows a fixed product configuration, uniform production process, and complete delivery package (packing list, installation drawing&manual, videos). This standardization eliminates errors, shortens the learning curve, and ensures rapid, worry-free assembly-even for first-time buyers.
