Introduction of Extra Wide Greenhouse
The extra-wide greenhouse (with a span of 12-14 meters) is a large-span greenhouse structure that adopts a lattice frame support system inside. Its core design is to achieve a large column-free space through the horizontal lattice trusses connected to the columns, which is suitable for scenarios with high requirements for the internal space.
Features
Extra-large span: With no intermediate columns, the internal clear width can reach 12 - 14 meters, ensuring high space utilization. It facilitates the passage of large equipment or the layout of water pools.
High structural strength: The lattice frame disperses loads through geometric rigidity, offering strong resistance to wind and snow. It is suitable for regions with extreme climates.
Flexible zoning: Functional areas such as aquaculture ponds and filtration systems can be partitioned as required, adapting to the aquaculture process.
Controllable environment: The roof is covered with translucent materials (such as PC boards or films). Combined with ventilation and shading systems, parameters like water temperature and dissolved oxygen can be precisely adjusted.
Corrosion resistance: The frame is mostly made of hot - dip galvanized steel or aluminum alloy, which is waterproof and rust - proof, suitable for high - humidity environments.
Application Scenarios (Aquaculture)
Intensive Aquaculture: It is used for fish farming, shrimp farming, etc. The large space allows for the installation of large-scale recirculating aquaculture ponds, increasing the yield per unit area.
Water Quality and Water Temperature Regulation: The thermal insulation performance of the greenhouse stabilizes the water temperature, protecting against the cold in winter and providing shading in summer, thus reducing energy consumption. It is combined with the ventilation system to balance the dissolved oxygen content.
Ecological Isolation: The enclosed structure can prevent external pollution (such as pathogens carried by rainwater), reducing the risk of diseases.
Special Aquaculture: It is suitable for varieties that are sensitive to light and temperature (such as bass, Litopenaeus vannamei), or high-value aquatic products that require simulating the natural habitat.
Greenhouse Supporting Systems
Automatic control shading system
Dynamic control of shading rate: According to the photoperiod requirements of different fish species (for example, salmon requires a shading rate of 70% - 80%, while tilapia requires 30% - 50%), a programmable controller is configured to automatically unfold the shading net from 08:00 to 16:00.
Anti - algae growth design: A shading net with an ultraviolet blocking rate of ≥ 90% is used to inhibit the explosive growth of algae on the water surface.
Manual/electric window opening system
Function: By adjusting the opening angle or degree of opening and closing, natural ventilation is enhanced to expel hot and humid air.
Manual window opening: It has a low cost and is suitable for small - scale greenhouses or scenarios with a limited budget.
Electric window opening: It supports automatic control and can be linked with temperature and humidity sensors to precisely adjust the ventilation efficiency.
Exhaust fan
Function: It actively exhausts hot air, accelerates air circulation, and can form a “negative - pressure cooling” effect when used in conjunction with a wet curtain

FAQ:
Q: Are you a factory or a trading company?
A: We are a manufacturer with a factory covering an area of 2,000 square meters and various production equipments.
Q: What is the material of the main structure of your greenhouse? How long can it be guaranteed to be used?
A: The main frame of our greenhouse is generally made of hot-dip galvanized steel. This material has super corrosion resistance. Under normal circumstances, with proper daily maintenance, its service life can reach 15 - 20 years. It can resist common natural disasters such as wind, rain, and snow pressure, providing a stable growing environment for the crops in the greenhouse.
Q: Before placing a large order, we'd like to buy a sample greenhouse to try it out first. Is that possible?
A: Yes. We can send you a small-scale greenhouse by LCL (Less than Container Load) sea shipping.
Q: I have a piece of land and I want to grow some vegetables or raise some fish, but I don't know what kind of greenhouse and what size I need. Can you help me with the design?
A: Of course. You can tell us the size of your land, your expected annual output of vegetables or fish, as well as the local climate information. Based on these data, we can design the style, size and price of the greenhouse for you. We'll also let you know approximately how many workers are needed and how long it will take to complete the installation, and how much yield you can expect in a year.
Q: Do you provide planting technical guidance after I purchase the greenhouse?
A: We have a professional planting technology team. After you purchase the greenhouse, according to the crop varieties you plant, we will customize a detailed planting plan for you, covering all aspects such as sowing time, planting density, fertilization and watering frequency, and key points of pest and disease prevention and control. During the planting process, you can contact our technicians via phone, video, etc. at any time, and they will answer your questions promptly.
Q: How long will it take to receive the greenhouse after placing an order?
A: Generally, for standard-specification greenhouses, production, transportation, installation and commissioning can be completed within 20 - 30 days after you place the order and the deposit arrives. However, if you customize special specifications or configurations, or the quantity you purchase is relatively large, it may take about 40 - 60 days. We will give you an accurate time estimate when signing the contract.
Q: What kind of assistance can you provide during the greenhouse installation?
A: We will provide several ways to help you with the installation: First, we'll provide written installation instructions; second, we'll offer online installation guidance; third, we'll dispatch engineers to your construction site for on-site installation guidance; fourth, if there is our local agent, our agent can also help you with the installation service.
Q: What are the quick solutions when encountering pest and disease problems?
A: First, our technical team will help you accurately identify the types of pests and diseases, which is the key to taking the right countermeasures. Then, according to different pests and diseases, we will provide corresponding biological control, physical control or chemical control solutions. For example, for common pests like aphids, we recommend using physical control methods such as yellow sticky traps combined with biological control methods like releasing ladybugs, so as to minimize the use of chemical pesticides, which can protect the environment while effectively controlling pests and diseases.
Q: What preparations should I make before installation?
A: First, obtain the building permit from the government if required. Second, prepare the tools according to the tool list we send you. Third, get the workers ready. Fourth, prepare the power supply if needed. Fifth, prepare a place to store the goods upon arrival to keep them from getting wet in the rain.
Q: What does your greenhouse after-sales service include?
A: We provide a one-year free warranty service. During the warranty period, for any parts of the greenhouse with non-artificial damage or quality problems caused by natural disasters, we will replace or repair them for free. After one year, we still offer long-term paid maintenance services.
