Discover the pinnacle of controlled environment agriculture with our Venlo Glass Multi-Span Greenhouse – a testament to Dutch horticultural innovation, designed to deliver unmatched crop quality and yield consistency. Crafted for commercial growers and agricultural enterprises demanding excellence, this greenhouse merges time-tested engineering with cutting-edge technology.
​

Unparalleled Structural Advantages
​
Heritage Design: Originating from the Netherlands, the Venlo structure features narrow gable spans (3.0-4.5m) that minimize shadow interference, ensuring uniform light distribution across all growing zones.
​
Reinforced Framework: Hot-dip galvanized steel profiles with 350g/m² zinc coating provide exceptional corrosion resistance, backed by a 30-year structural warranty. The interlocking truss system enhances stability in extreme weather.
​
Glass Integrity: 4mm/5mm clear tempered glass panels with 92% light transmittance – 10% higher than standard polycarbonate – creating an optimal photosynthetic environment for high-value crops.

​

Advanced Climate Management
​
Dual-Layer Insulation: Optional double-glazed units with low-emissivity (Low-E) coating reduce heat loss by 45%, maintaining precise temperatures even in sub-zero conditions.
​
Dynamic Ventilation:​
Motorized ridge vents (18% roof coverage) paired with sidewall louvers for efficient air exchange, reducing humidity-related diseases by 30%.
Integrated climate control system syncs with sensors to adjust vents, shading, and CO₂ levels in real-time, achieving ±0.5°C temperature accuracy.
​
Solar Optimization: South-facing roof inclination (25-30°) maximizes winter sunlight capture, while external retractable shading screens cut summer heat gain by 50%.
