Product Advantages
1
The main skeleton is made of Q235B and above grade hot-rolled steel to ensure the foundation strength and toughness. The surface is treated with hot-dip galvanizing technology, and the thickness of the galvanized layer is ≥ 180g/㎡, significantly higher than the industry standard, endowing the skeleton with excellent corrosion resistance. Designed to have a lifespan of over 15 years, providing long-term stable structural support for commercial planting.
2
The transmittance of the solar panel is ≥ 90%, which avoids crop burns and promotes photosynthesis.
3
Supports optional electric film rolling system, wet curtain fan cooling system, external shading system, internal insulation system, and IoT control cabinet. Users can remotely adjust environmental parameters such as temperature, light, water, and gas through their mobile phones or PCs to meet the needs of different crop growth stages.
4
Sainpoly relies on its own factory to achieve a 90% self-produced rate of core components, with traceable quality throughout the entire process from raw materials to finished products. The product has passed CE international certification and is supported by 15 patented technologies, establishing a comprehensive quality assurance system. Each batch of products follows the zero defect delivery standard to ensure that every product received by customers is stable and reliable.
5
We provide customized services for climate data collection, structural strength verification, foundation design, environmental control selection, irrigation schemes, and supplementary lighting systems at the project site. We also provide installation drawings and engineer installation guidance.

FAQ
1
Q: What is the insulation performance of this polycarbonate sheet vegetable greenhouse? What's the lowest temperature it can withstand?
A: Equipped with 8mm/10mm double-layer hollow polycarbonate sheets, thermal insulation screens and auxiliary heating systems, it can adapt to the extreme low temperature of -35℃ outdoors, and the indoor temperature can be stably maintained above 10℃, fully meeting the needs of off-season vegetable planting in northern areas.
2
Q: What is the wind and snow load resistance of the polycarbonate sheet greenhouse? Is it suitable for windy/snowy areas?
A: The standard configuration has a snow load resistance of 0.35kN/m² and wind load resistance of 0.35kN/m², which can be upgraded to 0.8kN/m² according to the local climate. The frame adopts hot-dip galvanizing process, which is fully suitable for extreme climate areas such as strong wind and heavy snow.
3
Q: What is the light transmittance of the polycarbonate sheet? Will it affect crop photosynthesis?
A: The light transmittance of double-layer polycarbonate sheet can reach 80%-85%, and the light enters the greenhouse in a diffuse way, which can avoid strong light burning crops, reduce indoor shadows, and make crops receive more uniform light, which is very suitable for planting leafy vegetables, flowers and other crops.
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.
② Provide detailed installation videos and manuals, with full remote assistance, and installation can be completed smoothly even for beginners.
5
Q: Does your polycarbonate sheet 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: Can I only purchase polycarbonate sheets and frames and assemble them by myself?
A: Yes. All components are pre-processed, numbered and packed in the factory, with installation drawings attached, supporting DIY assembly. We can also provide installation training videos as needed.
