Product Advantages
1
The main body adopts high-strength hot-rolled steel frame and is protected by hot-dip galvanizing. The standard zinc layer is ≥ 180g/㎡, and in high humidity or corrosive areas, a dual protection of ≥ 275g/㎡ galvanizing and spraying can be selected to suppress rust expansion from the source. The structure has sufficient load-bearing capacity and outstanding wind and snow resistance. The service life of the entire shed is not less than 15 years, and there is no need for large-scale repairs due to corrosion or deformation throughout the entire life cycle, greatly reducing annual maintenance expenses.
2
Using anti drip film with a light transmittance of ≥ 90%, the light distribution in the greenhouse is uniform and there are no dead corners. All parts of the crop can obtain sufficient light energy, and the leaf photosynthetic rate is significantly enhanced. The plant is characterized by thick stems and dark green leaves, and the coloring and sugar content of the fruit improve synchronously, providing a light environment guarantee for the production of high-quality agricultural products.
3
Built in intelligent control platform, integrating internal and external shading, insulation, film ventilation, and temperature control functions, and optional installation of IoT electrical control cabinet upgrade solution. By automatically sensing and regulating core factors such as light, temperature, water, and air, we provide precise environmental matching for high value-added crops throughout their entire growth cycle, effectively reducing manual inspection and operation costs, and helping growers achieve standardized, low loss, and refined management.
4
Factory direct supply: 90% self production rate, ensuring full process quality traceability. Through CE international certification, we have 15 patented technical supports to ensure zero defect delivery of batches of products.
5
We provide on-site meteorological parameter measurement, structural strength simulation verification, foundation and supporting system design, as well as selection and optimization of subsystems such as environmental control, irrigation, and supplementary lighting. At the same time, we deliver construction drawings and on-site engineer installation guidance to ensure that the greenhouse system is accurately adapted to the site conditions, providing users with complete technical support from planning to production stage.

Application and Solutions
Extremely cold in winter，conventional greenhouse vegetable crops will experience irreversible freezing damage.
Avoid freezing
Risk of snow collapse
High Light Transmittance
Lower Energy Consumption
Long life design
Avoid freezing
Winter is extremely cold, and conventional greenhouse vegetable crops will suffer irreversible freezing damage The synergistic effect of PO anti fog film and multi-layer internal insulation curtain significantly reduces nighttime heat loss, and the insulation rate increases by no less than 30%. More severe weather conditions can be upgraded by using double-layer hollow solar panels or hollow tempered glass, combined with reserved heating interfaces connected to heat sources, forming multiple anti freezing barriers to maintain the temperature inside the greenhouse above the crop safety threshold, completely eliminating the risk of freezing damage.

FAQ
1
Q: Can the span, bay width and eaves height of the multi-span greenhouse be customized?
A: Yes. The standard configuration includes spans of 8m/9.6m/10m, bay widths of 4m/5m, and eaves heights of 3m/4m/6m. Custom lengths and heights are available according to site conditions and planting requirements to adapt to various plot sizes.
2
Q: How long is the service life of the Multi-span greenhouse frame? Is later maintenance complicated?
A: The main frame is made of Q235B hot-rolled steel with hot-dip galvanizing (≥180g/m² zinc coating), offering a structural service life of over 15 years. Covering materials like PC sheets have a lifespan of more than 10 years and are easy to replace. Daily maintenance only requires regular cleaning and fastener checks, resulting in low maintenance costs.
3
Q: Can the Multi-span greenhouse be equipped with an intelligent control system? What functions does it support?
A: Yes. An optional IoT intelligent control cabinet enables precise regulation of temperature, light, water and gas. It automatically controls shading, ventilation, thermal insulation and heating systems, supporting remote monitoring and parameter presetting to meet the needs of precision farming.
4
Q: Do you provide installation services? Is remote guidance feasible?
A: We provide two modes: ① Send technicians from the headquarters for on-site guidance; ② Provide detailed installation videos and manuals, with full remote assistance, and installation can be completed smoothly even for beginners.
5
Q: Does your Multi-Span greenhouse comply with EU standards?
A: Yes. We have CE certification, and steel, polycarbonate sheets, sealants, etc. all comply with relevant EU standards, and can assist customers to pass local acceptance.
6
Q: Is the winter heating cost of the multi-span greenhouse higher than that of traditional greenhouses?
A: No. The double-layer hollow PC sheets and zoned thermal curtains reduce heat loss by more than 35%, lowering heating energy consumption by over 35% compared to single-layer film greenhouses and significantly cutting winter heating costs.
