Product Features

1. Single-Layer Agricultural Film Options: PE / EVA / PO

The Single-layer Film Multi-span Greenhouse uses a single layer of agricultural film. PE, EVA, and PO films can be selected according to the local climate, crop requirements, and project configuration.

• Good light transmission allows natural sunlight to enter the growing area directly.
• The structure provides good natural ventilation and helps reduce heat accumulation during warm seasons.
• Lightweight film is easy to install, replace, and maintain.
• The film system is suitable for seasonal cultivation, nursery production, and short-cycle crop rotation.
• The single-layer covering reduces unnecessary light loss and is particularly suitable for light-demanding crops.

PE film is a practical option for general applications. EVA film can be selected where improved low-temperature performance and anti-fog properties are required. PO film is available for projects requiring higher optical performance and a more advanced film solution.

2. Hot-Dip Galvanized Steel Structure

The main greenhouse frame is manufactured from carbon steel and processed with surface preparation and hot-dip galvanizing for corrosion protection.

The galvanized surface provides resistance to rust, outdoor moisture, and oxidation. Standardized structural components are assembled into a modular multi-span system, helping distribute loads across the greenhouse structure.

The frame is designed to provide stable support under normal outdoor conditions, including regular wind, frost, and light snow conditions, subject to local structural requirements and project specifications.

The steel structure is designed for long-term use, with a service life of more than 10 years under suitable operating and maintenance conditions.

3. Simple Structure, Fast Installation

A practical structural design and standardized components make installation relatively straightforward. Components are connected mainly through bolted assembly, reducing the need for on-site welding and specialized construction equipment.

The multi-span layout creates a large and organized internal growing space. Compared with traditional single-span structures, it makes better use of the available planting area and provides convenient access for workers, crop maintenance, weeding, harvesting, and small agricultural equipment.

4. Flexible Configuration and Controlled Investment

The greenhouse can be configured for basic cultivation, standard commercial planting, semi-automated management, or further greenhouse upgrades.

Dimensions can be adjusted according to the available land, terrain, crop type, and project requirements, including:

• Span width
• Bay spacing
• Eave height
• Overall length
• Ventilation configuration
• Optional greenhouse systems

The configuration can remain simple where only basic cultivation functions are required, while additional systems can be added when the project calls for greater environmental control.

Single-Layer vs. Double-Layer Multi-Span Greenhouses

To help growers and agricultural project planners select a suitable covering structure, the main differences between single-layer and double-layer film greenhouses are outlined below.

1. Single-Layer Multi-Span Greenhouse

• Positioning: Standard and practical structure using PE, EVA, or PO single-layer film
• Main advantages: Simple structure, good light transmission, natural ventilation, and convenient temperature control
• Performance: Basic heat retention, mainly suitable for seasonal or mild-climate cultivation
• Typical applications: Spring and summer growing, warm climates, vegetables, fruits, and general nursery production

The single-layer structure is particularly suitable for projects where ventilation, natural light, simple maintenance, and flexible seasonal cultivation are important.

2. Double-Layer Multi-Span Greenhouse

• Positioning: Enhanced structure for colder growing conditions
• Main advantages: Two-layer covering creates an insulating air layer between the films
• Performance: Better heat retention and frost protection than a standard single-layer structure
• Typical applications: High-latitude or colder regions, autumn and winter cultivation, and crops requiring improved temperature stability

The choice between the two structures should be based on local climate, crop requirements, winter temperature, ventilation needs, and the level of environmental control required.

Optional Supporting Systems

The Single-layer Film Multi-span Greenhouse can be equipped with different standard or upgraded systems according to project requirements. This allows the greenhouse configuration to remain practical without adding unnecessary equipment.
