6. FAQ

Q1: What is a multi-span film greenhouse and how is it different from a single-span greenhouse?
A multi-span film greenhouse connects multiple greenhouse spans (bays) together using a galvanized steel structure, covered with plastic film. Compared to single-span structures, it offers larger continuous growing area, better space utilization, and lower cost per square meter for large-scale farming.
Q2: What type of film material do you use, and how long does it last?
We use high-quality PE or EVA greenhouse film with UV-resistant and anti-aging treatment. Under normal conditions, the film typically lasts 3-5 years depending on climate and film specification, and can be replaced without changing the main structure.
Q3: Can the structure withstand strong wind and snow load?
Yes, the steel structure specification (column spacing, pipe diameter, gutter height) is designed according to your local wind and snow load requirements to ensure structural safety.
Q4: What ventilation systems are available?
Standard configurations include roof ventilation, side ventilation, and insect-proof netting. Natural ventilation and mechanical (fan-pad) cooling systems can also be added based on your climate and crop needs.
Q5: Is this greenhouse suitable for large-scale commercial farming?
Yes, multi-span film greenhouses are widely used for large-scale vegetable, fruit, and cash crop production due to their cost-effectiveness and scalability - projects can range from a few thousand to hundreds of thousands of square meters.
