Product Description
The Sainpoly Gothic Tomato Factory adopts structural reconstruction tailored to the physiological characteristics of modern indeterminate tomatoes, specially built for high-density planting in large tomato parks. Its Gothic spire can be customized to 6–8 meters or higher. It not only creates an excellent growth buffer zone for crops but also improves top natural ventilation efficiency via optimized aerodynamic layout.
Manufacturing advantages: To bear the heavy weight of tomato vines in the middle and late fruiting stages, the greenhouse main frame uses S350GD high-strength special steel from Wuhan Iron and Steel / Shougang. The truss structure is validated by CFD stress simulation, with redundant vine load capacity of 0.5–0.6kN/m². All structural components are precision processed on Sainpoly’s fully automatic CNC production line, with positioning hole error ≤0.5mm, guaranteeing seamless assembly on large construction sites. The surface is treated with industrial-grade hot-dip galvanizing, zinc coating ≥600g/m², delivering 20-year corrosion resistance under humid tomato growing conditions. Sainpoly offers full-process EPC services including park planning, production scheduling, logistics delivery, on-site installation and tomato agronomy training.

Product Advantages
1
The main truss adopts a reinforced triangular stable structure. Hanging vine steel wires are deeply integrated with gantry frames, ensuring the main greenhouse structure stays stable during peak yield periods, with safety performance far exceeding industry standards.
2
The large-space Gothic design increases air buffer volume by more than 20% compared with traditional greenhouses. Coupled with intelligent internal circulation fans, it effectively mitigates drastic temperature and humidity fluctuations inside the greenhouse and reduces tomato late blight incidence.
3
The self-production rate of core components exceeds 90%. Sainpoly’s annual production capacity of 200 hectares cuts the average per-square-meter cost of large-scale projects by 10%–15%.
4
Steel components undergo full-process hot-dip galvanizing, and Dacromet bolts are used at key positions. They maintain structural rigidity under long-term spraying and high-humidity conditions, with a design life of up to 20 years.
5
Each zone is independently equipped with nutrient solution circulation, supplementary lighting and shading systems. The central IoT platform manages the entire farm via one screen, enabling a single operator to oversee tens of thousands of square meters of tomato planting area.

FAQ
1
Q: How does Sainpoly Gothic Tomato Greenhouse guarantee structural safety in high snow-load regions such as North America?
A: Sainpoly adopts S350GD high-strength steel frame. The curvature of its Gothic spire is optimized via CFD fluid dynamics simulation to allow snow to slide down naturally along the curved surface. Our reinforced truss specially designed for tomato hanging vines can bear a combined snow load and crop vine load of 0.6–0.8kN/m², far exceeding the standards for conventional greenhouses.
2
Q: What technical advantages do the main columns of the Sainpoly product have against the vertical heavy load from indeterminate tomatoes?
A: Our main columns adopt a thickened hot-dip galvanizing process (zinc coating thickness ≥85μm). The load-bearing redundancy design of a single column exceeds 3.5 tons. This industrial-grade strength can fully sustain the continuous vertical tension exerted on the framework during the peak fruiting stage of tomatoes and eliminate structural deformation.
3
Q: The humidity inside large tomato greenhouse clusters is extremely high. How does your modular zoning system prevent late blight?
A: Each zone is equipped with independent temperature & humidity sensors and high-level environmental control windows. The central IoT platform precisely regulates vapor pressure difference (VPD). The system automatically drives air circulation and discharges surplus moisture, fundamentally reducing late blight triggered by uneven humidity in tomatoes.
4
Q: What is the maximum customizable eave height of the Sainpoly greenhouse? How does it help boost tomato yield?
A: Our Gothic structure supports custom eave heights of 6–8 meters. It delivers ample vertical growing space for long-cycle tomato vines, adds a top heat buffer zone, improves air circulation, and effectively raises output per unit area.
5
Q: To what extent can the central IoT platform inside the greenhouse support remote operation and maintenance for large-scale tomato factories?
A5: We provide an open remote data interface, enabling factory technical experts to diagnose the status of sensors and actuators online. For projects at the hundred-hectare scale, it supports one-click deployment of environmental control strategies across the whole site, and guarantees rapid spare parts supply worldwide.
6
Q: Can Sainpoly meet the requirements of international material standards for cross-border tomato projects?
A: Yes, fully. Sainpoly has a strong delivery capacity of 200 hectares per year. Our products are CE certified. The steel and connectors comply with mainstream engineering standards of the EU and North America, and we can provide cross-standard equivalent load comparison reports.
