Product Description

The Sainpoly Venlo Greenhouse is specially designed for commercial planting around the world, and is not afraid of extreme weather conditions such as severe cold, heavy snow, strong winds, and high temperatures, achieving stable production throughout the year.To address the pain points of low temperature, weak lighting, and high energy consumption in winter, we adopt an integrated solution of double-layer insulated glass, internal insulation curtain, and reserved heating system.

This ensures that the temperature inside the greenhouse can be maintained above 10 ℃ at night during winter, and there is sufficient daylight during the day to meet the growth needs of warm vegetables. The main body of the greenhouse adopts a Wenluo style truss structure, with a maximum snow load resistance of 0.8kN/m2, wind resistance of level 12, and a service life of over 20 years. We provide one-stop services from climate adaptation design, factory customized production to on-site installation and commissioning.

Product Advantages

Sainpoly's Venlo greenhouse is used for vegetable cultivation 12 Durable and sturdy structure: The main frame is made of Q235B or higher high standard steel, which has been hot-dip galvanized with a galvanized layer thickness of ≥ 180g/㎡ (far exceeding the standard for ordinary steel). A single column can bear several tons of weight, and the overall structure has a service life of over 15 years. Its ability to resist snow pressure and wind erosion is industry-leading.

Sainpoly's Venlo greenhouse is used for vegetable cultivation 13 Maximizing sunlight utilization: 91% ultra-high transmittance, paired with diffuse glass options, strong light becomes soft light, crops are not burned or yellowed, higher light utilization rate, and more stable yield.

Sainpoly's Venlo greenhouse is used for vegetable cultivation 14 Intelligent environment control system: It can integrate modules such as electric film rolling, wet curtain fan, external sunshade, internal insulation, and IoT intelligent control cabinet. All subsystems can be remotely controlled through mobile phones or PCs to achieve automated management of greenhouse environments.

Sainpoly's Venlo greenhouse is used for vegetable cultivation 15 Direct supply from the source factory: The self-produced rate of core components reaches 90%, reducing intermediate links, controllable delivery time, and cost optimization. Holding CE certification and 15 technical patents, relying on a strict three inspection system, our products leave the factory with zero defects.

Sainpoly's Venlo greenhouse is used for vegetable cultivation 16 Customized services: 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.

Application and Solutions

Extremely cold in winter，conventional greenhouse vegetable crops will experience irreversible freezing damage.

Avoid freezing

Extremely cold climate in winter,vegetables freeze to death.

We adopt an integrated configuration of double-layer insulated glass, internal insulation curtains, and reserved interfaces for the heating system, which can maintain a stable nighttime temperature of over 10 ℃ in the greenhouse.

High Light Transmittance

Short light exposure time leads to slow vegetable growth

Using high transmittance glass covering material (transmittance ≥ 91%), and optional LED artificial supplementary lighting system, the daily effective lighting duration is extended to 14 hours to ensure the normal growth rate of crops.

Risk of Snow Collapse

Snow collapse risk prevention and control system: using reinforced truss structure, increasing the cross-sectional size of the main skeleton, and connecting nodes with high-strength bolts. If necessary, a snow melting pipeline system can be installed at the ridge to prevent snow accumulation. The design value of snow load can reach 0.2-0.8kN/m2, meeting the requirements of anti snow load in snowy areas.

High energy cost

Adopting double-layer insulated glass covering material to enhance the insulation performance of the enclosure structure, combined with zoning control system, reduces heating energy consumption by more than 30%.

Long life design

Traditional greenhouses have a short lifespan. The factory adopts hot-dip galvanized steel frame and insulated glass, with a warranty period of 10 years and a design life of 20 years.
