Galvanized Multi Span Film Greenhouse with Side Vents for Vegetable Farms

Product Description

This multi span greenhouse is built for farms that need reliable covered production area without the cost of a permanent glasshouse. The frame uses hot dip galvanized steel or aluminum alloy, and the covering can be PO or PEP film, or glass where a longer service life is required. Span width runs 8 m to 12 m with length set to the site, and gutter height from 3 m to 4.5 m gives clearance for trellised crops and light equipment. Film covering passes 85 to 95 percent of available light and carries a UV stabilized coating that extends service life to about three years. Roof vents and side vents are fitted as standard, with automated ventilation available where the local climate demands it. Growers run the structure for vegetables, fruit, flowers and seedling raising, and the same frame serves for overwintering livestock in colder districts. Width, length, bay count and covering are all specified per order, so the building matches the plot instead of forcing the plot to match a standard kit.

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.
