Multi Span Film Greenhouse with Galvanized Steel Frame for Turnkey Projects

Product Description

 

Product Description

Product Overview

This multi span film greenhouse is quoted as a complete package: frame, cover, vents and the drawings to put it up. Spans run 8m to 12m, length goes to 100m, and gutter height is 3m to 4.5m with the ridge at 6m to 8m, so a walk in plastic greenhouse on this frame takes beds, trellis lines and a small cart without squeezing. The frame is hot dip galvanized steel or aluminum alloy, and the PO or PEP cover passes 90% to 95% of daylight with UV stabilizers for a film life of about 3 years. Roof vents, side vents or automated openers handle airflow, and heating can be added where nights turn cold. Vegetables, fruit, flowers and seedlings all run under the same roof, and extra bays bolt on later. Send the span, length and crop and we will price the polytunnel frame and cover as one order.

1. Overview

A Film Greenhouse, also known as a Polyethylene (PE) Film Greenhouse, is a cost-effective and versatile structure designed for agricultural and horticultural purposes. It utilizes polyethylene film as the primary covering material, providing an optimal environment for plant growth by controlling temperature, humidity, and light conditions.

2. Structure and Materials

Frame Material:
The framework is typically constructed from galvanized steel or aluminum alloy, ensuring durability, corrosion resistance, and the ability to withstand environmental stresses.
Covering Material:
The greenhouse is covered with multi-layer polyethylene (PE) film, usually ranging from 0.08 mm to 0.2 mm in thickness. Advanced films may include UV stabilization, anti-drip coatings, and thermal insulation layers to enhance performance.
Foundation:
The structure is anchored to a concrete foundation or ground posts, providing stability and longevity.

3. Key Features

Light Transmission:
The PE film offers 85% - 90% light transmission, ensuring sufficient natural light for photosynthesis while diffusing sunlight to prevent plant burn.
Thermal Insulation:
Multi-layer films create air pockets that improve thermal insulation, maintaining a stable internal temperature and reducing heating costs in colder climates.
UV Protection:
UV-stabilized films protect plants from harmful ultraviolet rays while extending the lifespan of the covering material.
Ventilation Systems:
Film greenhouses are equipped with side vents, roof vents, or manual/automatic roll-up systems to regulate airflow, humidity, and temperature.
Expandability:
The modular design allows for easy expansion or customization to meet specific crop requirements.
