Multi-Span Plastic Film Sawtooth Greenhouse
- HONGYANG
- CHINA
Multi-span sawtooth greenhouse has the advantages of high land utilization rate, high mechanization degree of indoor operation, less energy consumption per unit area and uniform indoor temperature and light environment.
Product Description
The sawtooth greenhouse is a type of roof structure arranged like sawtooth. The sawtooth skeleton structure consists of a column, a beam, a sawtooth column, a sawtooth half arc and a zigzag brace. The height of the sawtooth in the sawtooth greenhouse is determined according to the span of its individual sawtooth, which is at least 1.5 meters high. There are vertical vents on the roof of the sawtooth greenhouse, the ventilation effect of the sawtooth greenhouse is good.
Product Characteristics
Structural design: The sawtooth greenhouse is uniquely designed to maximize the efficiency of lighting. By adjusting the Angle and length of the sawtooth, it can adapt to the sunshine conditions of different latitudes and regions, ensuring that the greenhouse gets sufficient sunlight.
Natural ventilation effect: the natural ventilation effect of the sawtooth greenhouse is better, especially in the case of external shading, the natural ventilation effect can basically reach the temperature difference between indoor and outdoor 3~5℃. The vertical window of the sawtooth greenhouse roof is located at the highest point of the greenhouse, and the indoor hot air rises and exchanges with the outdoor air through the vertical window, thus achieving the best natural ventilation effect.
Rain protection: The sawtooth roof helps rainwater slide down the eaves, reducing the risk of rainwater accumulation and improving the storm resistance of the greenhouse.
Easy maintenance: The sawtooth greenhouse uses high-strength and durable materials, such as reinforced plastics, to ensure its long-term stability and resistance to wind and rain erosion.
Intelligent control system: The sawtooth greenhouse is also equipped with an advanced irrigation system and intelligent control system, which can be accurately controlled according to the growth needs of plants and environmental conditions to ensure the healthy and efficient growth of plants.
Economical applicability: The sawtooth greenhouse shows good adaptability in areas with hot summers and frequent rain, because the vents on the top facade of the zigzag are not affected by rainfall and do not need to be closed.
Product Deatails
greenhouse structure
The greenhouse structure comform with hot-dip galvanized steel, ensures robust resilience against corrosion, extending greenhouse lifespan and maintaining structural integrity in various weather conditions. Hot-dip galvanized steel not only provides enduring support but also offers peace of mind to growers, allowing for long-term cultivation without concerns about deterioration or maintenance issues.
covering material
Greenhouse covered with PE (polyethylene) film or PO (polyolefin) film, with PE manufactured through a 3-layer process and PO through a 5-layer process, both featuring UV coating and anti-drip, anti-aging properties to ensure longevity and performance. These films come in thickness options of 120 microns, 150 microns, or 200 microns, offering growers flexibility to choose the most suitable option for their specific climate and cultivation needs.
inner sunshade system
In summer,This system effectively lowers the internal temperature, while in winter and at night, it prevents heat loss. The system offers versatile solutions to regulate climate conditions, ensuring optimal growing conditions year-round and enhancing energy efficiency.
ventilation system
There with rows of sawtooth-shaped roofs or opening along one side of the greenhouse. These opening can be opened and closed to control airflow and temperature inside the greenhouse. As warm air rises, it escapes through the open vents, creating a natural convection current that draws in cooler air from outside, effectively regulating the internal climate. This passive ventilation system helps maintain optimal growing conditions while reducing the need for mechanical cooling, contributing to energy efficiency and sustainable greenhouse management.
irrigation system
Sawtooth greenhouse irrigation systems employ a combination of drip irrigation, overhead sprinklers, or misting systems, depending on the specific needs of the crops and the greenhouse environment. These systems are often automated and controlled by timers or sensors to provide the right amount of water at the right time, minimizing water wastage and labor costs.
Soilless cultivation system
The soilless cultivation system allows plants to grow without soil, utilizing nutrient-rich water solutions to deliver essential nutrients directly to the plant roots for optimized growth in controlled environments.
External sunshade system
The external sunshade system can effectively block the light outside the greenhouse, so that part of the sunlight enters the greenhouse, and ensure that the crops avoid strong light burns and thus play a cooling and shading role. By adjusting the opening and closing of the sunshade net, to meet the demand for light in the greenhouse.
Control System
The control system of the greenhouse is composed of a distribution box and a cable, and the switch of each system in the greenhouse can be adjusted by the button of the distribution box, such as the external sunshade system, which can be opened or closed by the button.
