The multi-span greenhouse is the most commonly used structure for large-scale agricultural production. Its key feature is the modular arrangement and connection system, typically assembled using fasteners or steel structures to create a continuous, large growing area.
“Multi-span” refers to the structural arrangement rather than a specific greenhouse type. By integrating different structural designs and covering materials, multi-span greenhouses can serve various functional purposes. Compared to single-span greenhouses, multi-span structures offer greater operational flexibility, centralized management, and compatibility with mechanized farming, such as small-scale automated equipment, irrigation systems, and climate control technologies, improving overall production efficiency.
In this context, we specifically refer to multi-span greenhouses with an arched structure covered by plastic film. If other covering materials are used (such as glass or polycarbonate panels), even with a multi-span layout, they are classified under distinct greenhouse types, such as Venlo Greenhouses or Polycarbonate Greenhouses.
