Agricultural Film Greenhouse with Galvanized Steel Frame for Vegetable Growing

Product Description

Agricultural film greenhouse uses a galvanized steel frame with PO or PEP plastic film as the covering, giving growers a low cost structure that still controls temperature, humidity and light. Film thickness ranges from 0.08 mm to 0.2 mm and light transmission reaches 90 to 95 percent, which keeps photosynthesis steady through the growing season. Spans run from 8 m to 12 m, lengths from 10 m to 100 m and heights from 3 m to 8 m, all adjustable to the site. Roof vents and side vents can be manual or automated, and an optional boiler or radiant heating system extends winter production. Three layer compressed film traps air pockets for better insulation, and UV stabilized coating gives the plastic a 3 year service life. The frame suits vegetables, fruit, flowers, seedlings and livestock overwintering. For B2B buyers, custom span and length, bulk film supply and container loading are available, and the design can be expanded module by module. This film greenhouse suits commercial farming and nursery production.

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.
