Product Description
We have upgraded the anti-corrosion grade of the greenhouse skeleton to meet the strict humidity requirement (80%–90% RH) for high-frequency turnover in large-scale cucumber production bases. All greenhouse components undergo hot-dip galvanizing at Sainpoly’s modern facility, with zinc coating thickness ≥85 μm. Combined with our self-produced diffuse reflection anti-drip covering material, the Gothic arc-shaped structure converts direct sunlight into soft scattered light that penetrates deep into foliage, boosting the photosynthetic area of cucumber plants by 15%.
The greenhouse integrates a high-pressure micro-fog cooling and water & fertilizer integration system, coordinated by Sainpoly’s intelligent environmental control brain to sustain vigorous cucumber growth even during hot summer periods. Sainpoly’s annual production capacity exceeds 200 hectares. Our triple inspection system guarantees every steel frame features precise hole positioning and burr-free surfaces, satisfying high delivery standards for cucumber factories.

Product Advantages
1
The skeleton features a dense, uniform zinc layer with excellent performance in salt spray and damp-heat resistance tests, ensuring a structural service life of over 18 years in cucumber factories operating under long-term high humidity.
2
The scientifically designed Gothic curvature pairs with special covering materials to deliver uniform lighting for cucumber plants from top to bottom, greatly reducing the rate of curved and deformed cucumbers.
3
Modular zoning fitted with high-pressure atomization and dehumidification units. The central control platform achieves precise VPD (Vapor Pressure Deficit) control, boosting cucumber growth rate by more than 10%.
4
Multi-span structures covering dozens of hectares. Highly integrated gutter drainage and nutrient solution recirculation pipe networks cut labor for per-hectare operation and maintenance, bringing remarkable economies of scale.
5
We hold 15 greenhouse structure patents, with an annual production capacity exceeding 200 hectares and an in-house core component production rate above 90%. We support fast customs clearance and delivery worldwide.

FAQ
1
Q: The cucumber planting environment is extremely humid. What standards does the Sainpoly Gothic cucumber greenhouse meet in terms of anti-corrosion treatment?
A: For the high-humidity condition of 80%–90% RH inside cucumber greenhouses, we adopt a full-component hot-dip galvanizing process with zinc coating adhesion ≥600g/m². At critical rust-prone joints, we use Sainpoly’s patented Dacromet anti-corrosion bolts to guarantee a stable, rust-free structure for 20 years.
2
Q: What unique design does the cooling system of the Sainpoly Gothic structure have for tropical summer high temperatures?
A: We integrate our self-developed high-pressure micro-fog cooling system with a large centrifugal fan matrix. Combined with the large-space convection characteristics of the Gothic spire, the greenhouse interior temperature can be rapidly lowered by 5–8℃ in summer without raising disease risks, preventing cucumbers from high-temperature dormancy.
3
Q: What specific effects does the diffuse reflective film adopted by Sainpoly have on improving cucumber fruit quality?
A: The combination of the Gothic curved roof and diffuse reflective film eliminates light shadows inside the greenhouse, ensuring sunlight scatters evenly onto the middle and lower sections of cucumber plants. It effectively reduces the rate of deformed cucumbers and yellow-headed cucumbers caused by uneven light exposure, greatly boosting the commercial fruit rate.
4
Q: How do you achieve parallel precision management of multiple cucumber varieties through the modular zoning system?
A: Each planting zone is equipped with an independent water-fertilizer proportioning loop and sensor array. Via the central IoT platform, administrators can set dedicated fertigation logic for cucumbers of different varieties or growth cycles to realize granular precision production.
5
Q: What is Sainpoly’s delivery capacity for large-scale cucumber supply guarantee projects in regions such as the Middle East?
A: Sainpoly owns a vertical manufacturing chain with an annual output of 200 hectares. We offer standardized component packaging solutions for ultra-large projects, supporting parallel construction and phased delivery across different zones, enabling customers to achieve "first-phase planting, rapid yield.
6
Q: Can Sainpoly’s automated water and fertilizer system handle high salinity and alkalinity in local water sources?
A: Yes. Our integrated water & fertilizer unit features high-precision electrical conductivity (EC) and pH real-time monitoring & correction functions. It can automatically adjust formulas based on cucumbers’ nutrient sensitivity, securing stable yields under complex water quality conditions.
