Product Description
The large-scale leafy vegetable supply guarantee base is built to create a "fast-moving consumer goods workshop" in agriculture. In response to the large footprint and fast turnover of leafy vegetable projects, we adopt standardized, prefabricated engineering design. Backed by Sainpoly’s annual capacity of 200 hectares, the core frame undergoes fully automated processing, enabling delivery of 100-hectare-scale projects within 120 days. It features large-span Gothic trusses (main material S350GD) with an internal column-free design, greatly facilitating automated harvesting and sowing machinery operations. All steel components come with a zinc coating ≥85μm and receive special sealing optimization for high-humidity nutrient solution environments. The greenhouse integrates an efficient wet curtain-fan system and intelligent environmental control to keep leafy vegetables fresh, tender and non-bolting even in hot summer.

Product Advantages
1
Gothic large-span pillarless design, specially customized for vertical leafy vegetable racks or NFT tracks, boosting output per square meter by more than three times.
2
Optimized Gothic skylights interlock with the wet curtain and fan system. Air inlet height and wind speed are precisely calculated to maintain stable temperature and humidity inside the greenhouse with no localized high-temperature zones.
3
Over 95% standardized components. Zero on-site welding and cutting, enabling fast construction and phased commissioning for large-scale supply guarantee bases.
4
Direct sales under the Sainpoly brand. Boasting a vertical supply chain with an annual output of 200 hectares, it delivers 100% traceable core components and exceptional batch consistency.
5
Premium raw materials plus industrial-grade thickened anti-corrosion treatment. 20-year structural service life, far lower asset depreciation rate than conventional greenhouses, with remarkable residual value recoverable in later stages.

FAQ
1
Q: How does the Sainpoly Gothic greenhouse for leafy vegetables achieve rapid turnover of over 10 crops per year?
A: We have optimized the large-span, pillar-free space to perfectly fit automated NFT hydroponic racks. Together with factory-prefabricated standardized installation components, the greenhouse enables mechanized rapid sowing and harvesting operations, greatly shortening the crop turnaround time for each batch of leafy vegetables.
2
Q: Lettuce is prone to bolting and turning bitter in summer. How does the Sainpoly greenhouse solve this problem via structural design?
A: It takes advantage of the high-space thermal buffer zone created by the Gothic spire. Combined with fully-open top ventilation windows and Sainpoly self-produced wet curtain-fan matrix, the greenhouse maintains the cool microclimate preferred by leafy vegetables in hot seasons and prevents bolting.
3
Q: How does Sainpoly ensure ultra-fast delivery for 100-hectare leafy vegetable supply base projects?
A: Sainpoly has a strong annual production capacity of 200 hectares. We adopt modular container shipment and prefabricated construction modes, achieving seamless handover from factory prefabrication to on-site assembly, which greatly shortens the commissioning cycle for large-scale bases.
4
Q: What is the anti-corrosion performance of Sainpoly’s framework in the high-humidity and slightly acidic environment of leafy vegetable hydroponics?
A: Our framework is fully hot-dip galvanized (zinc coating thickness ≥85μm), and key connectors have passed 1000-hour salt spray testing. This guarantees the greenhouse maintains a structural service life of more than 15 years under long-term exposure to hydroponic nutrient solution environments.
5
Q: How does Sainpoly’s central IoT system help cut management costs for large leafy vegetable parks?
A: The system delivers fully automatic closed-loop control for environment regulation and irrigation. One display screen enables real-time monitoring of the entire park. It not only allows a single operator to manage 10,000 square meters efficiently, but also reduces power consumption by over 20% via intelligent algorithms.
6
Q: Does Sainpoly offer flexible construction solutions for leafy vegetable bases with expansion plans?
A: Yes. We support phased construction and delivery. Independent projects start from 3,000 square meters. We can deliver the demonstration zone first and reserve IoT system interfaces, enabling seamless integration of the full-park system for future expansion.
