1.Product Overview
This Multi-Span Round-Arch Poly Tunnel Greenhouse is a large-scale continuous plastic-film horticultural facility. It adopts integrated arched roof design and hot-dip galvanized steel framework, covered with high-performance UV-stabilized poly film. It is widely applied in commercial vegetable planting, flower production, seedling propagation, hydroponics and agricultural sightseeing. With reliable wind and snow resistance, it offers spacious connected growing zones, ideal for large farms pursuing centralized management and year-round protected crop cultivation.

2.Product Features
It has connected round arch roofs that facilitate snow sliding and disperse wind load effectively. The whole skeleton uses thickened hot-dip galvanized steel for excellent anti-corrosion performance. The high-transmittance poly film features anti-aging and anti-drip properties. It reserves installation positions for outer shading, top ventilation, fan-pad cooling, internal thermal screen and fertigation systems. Span, bay and height can be customized. Prefabricated parts enable orderly assembly on site for large-area projects.

3. Core Functions
This multi-span poly tunnel greenhouse stabilizes internal light, temperature and humidity for crops. The shading system blocks intense sunlight to avoid plant sunburn. Ventilation and cooling equipment prevent overheating in summer, while the film enclosure preserves heat to reduce cold damage in winter. It shields crops from heavy rain, strong wind, snow and pests. The continuous layout simplifies unified irrigation, fertilization and daily management to realize stable off-season high-yield planting.

4.Competitive Advantages
We are the direct manufacturer supporting customized orders with factory competitive prices. Compared with single-span tunnels, this connected multi-span design saves steel consumption and land occupation ratio, greatly improving space utilization. It is more cost-effective than glass multi-span greenhouses while retaining complete intelligent supporting options. We provide full sets of accessories, construction guidance and after-sales service. Bulk procurement enjoys favorable discount terms for overseas large farm projects.
