DETAIL
A custom greenhouse can be the foundation for precision agriculture, and the Dongying City Venlo-type glass greenhouse project is a clear example of that principle in action. Designed, manufactured, and installed by Sunmax Greenhouse, this turnkey solution reflects how modern greenhouse engineering can transform regional agricultural capabilities while meeting specific climate and cultivation requirements.
Located in Dongying, a city in Shandong Province, China, this greenhouse facility was developed for a local agricultural enterprise focused on high-value crop cultivation. The project covers over 9,000 square meters and uses the Venlo-type glass greenhouse structure—an industry-proven model for maximizing light transmission and long-term durability.
The greenhouse serves multiple functions: it supports year-round crop production, enables agricultural demonstration, and contributes to regional innovation in controlled-environment farming. Unlike a diy greenhouse built for home use, this facility was engineered with commercial-level automation and environmental controls, ensuring consistency across seasons and weather conditions.
The greenhouse features a Venlo-type structure made from hot-dip galvanized steel, chosen for its high tensile strength and corrosion resistance. The Venlo design includes a three-ridge roof system, which improves wind resistance and supports effective snow load distribution—a crucial factor in northern coastal areas like Dongying, where seasonal snowfalls can occur.
Each bay is equipped with low-iron tempered glass panels that allow for maximum light penetration (over 90% transmission rate), which is essential for light-demanding crops such as tomatoes, cucumbers, and peppers. Unlike a lightweight greenhouse kit, this industrial solution is designed to last over 20 years with proper maintenance, making it a high-value investment for commercial growers.
To maintain ideal growing conditions, the greenhouse is equipped with a full suite of integrated environmental systems, including:
Automatic ventilation: Roof vents and side vents controlled by a central system ensure effective air circulation.
Shading system: Internal shading curtains reduce solar gain during summer months while preventing heat loss in winter.
Heating system: Hot water pipes and circulation pumps maintain a stable temperature during colder periods, ensuring uninterrupted crop growth.
Cooling system: A fan-and-pad evaporative cooling system reduces interior temperatures during high heat, particularly in July and August.
Irrigation and fertilization system: An integrated fertigation unit allows for precise water and nutrient delivery, supporting optimal plant health.
Supplemental lighting: Energy-efficient LED grow lights extend the photoperiod during low-light seasons.
These systems are operated via a centralized digital controller that can be accessed remotely. The control logic is based on real-time data from temperature, humidity, light, and CO₂ sensors throughout the facility.
What sets this project apart is not just the scale, but the level of custom greenhouse adaptation based on local conditions in Dongying. The area is known for its coastal microclimate—humid summers, cold winters, and strong winds. These environmental factors were taken into account during the engineering phase.
The structural frame was reinforced beyond standard parameters to ensure long-term stability. Wind resistance exceeds 0.5 kN/m², and snow load capacity is designed at 0.3 kN/m². The glass used is double-layered at the roof ridge junctions to prevent heat loss during winter months.
In addition, the irrigation system was configured to use local groundwater, filtered and treated on-site to meet crop-specific pH and EC requirements. This not only reduces operating costs but also supports sustainable water resource management—delivering a tangible solution instead of broad claims around environmental friendliness.
Our team managed the project from initial consultation through to final handover. Services provided included:
Site evaluation and planning
Structural and system design
Material production and quality inspection
Logistics and customs documentation
On-site installation with multilingual project supervisors
Commissioning and operator training
The construction was completed within a 4-month timeline, despite challenges such as regional transport delays and on-site power supply limitations. Through close coordination with the client and local contractors, the project remained on schedule and within budget.
The Dongying City Venlo-Type Glass Greenhouse represents the intersection of robust engineering, environmental adaptation, and commercial farming needs. It stands as a successful implementation of Sunmax’s capabilities in delivering advanced, scalable greenhouse solutions.
For agricultural businesses seeking more than a diy greenhouse, and requiring more flexibility than a basic greenhouse kit, Sunmax provides tailored solutions backed by real-world results. From structure to system, from installation to operation—every phase is designed to support yield, efficiency, and long-term viability.
