Commercial Single Span Film Greenhouse | High Tunnel Poly Structure

Our single span plastic film greenhouse (high tunnel structure) provides a cost-effective, durable, and highly efficient growing environment for agricultural crops, flowers, and nursery plants. Designed with a classic gothic or round arch profile, this single-bay structure offers high structural stability against wind and snow loads while maximizing internal space for cultivation. Built using high-strength hot-galvanized steel piping and high-transmittance PE/PO agricultural film, it creates an optimal microclimate that protects crops from extreme weather, UV radiation, and outdoor pests.

Key Features & Structural Highlights

• Hot-Galvanized Steel Frame Constructed from heavy-duty hot-dip galvanized steel pipes that deliver exceptional resistance to rust, corrosion, and humidity. The sturdy steel arch framework ensures long-lasting structural integrity under tough outdoor farm conditions.

• High-Transmittance UV-Protected PE/PO Film Covered with high-clarity agricultural plastic film engineered with anti-drip, anti-fog, and UV-stabilized properties. The film allows maximum natural sunlight penetration for uniform plant growth while helping retain internal heat during cooler night temperatures.

• Manual Side-Wall Roll-Up Ventilation System Equipped with manual hand-crank film roll-up winches installed along the sidewalls. This allows growers to easily roll up the lower film layers for quick natural air exchange, effective temperature regulation, and humidity control during hot weather.

• Large Framed Sliding Door Access Features a sturdy sliding door setup at the end walls for smooth entry and exit. The wide doorway allows easy passage for farm personnel, wheelbarrows, seed trays, and portable agricultural tools.

• Wind & Snow Resistant Arch Design The arched roof structure prevents water accumulation during rainstorms and sheds snow effectively in colder seasons. Reinforced cross-bracing and wind ties provide added lateral stability across the full length of the tunnel.

Versatile Agricultural Applications

This single-bay poly tunnel greenhouse is adaptable for a wide variety of farming and horticultural setups:

• Vegetable & Fruit Cultivation: Ideal for growing tomatoes, cucumbers, peppers, leafy greens, and berries under protected conditions.

• Commercial Floriculture: Excellent environment for cut flower production and nursery plant propagation.

• Season Extension: Enables early spring planting and extends harvesting well into late autumn or early winter.
