1. Product Overview
This single-span arch greenhouse is a standalone tunnel greenhouse solution designed for small and medium-sized commercial planting. It adopts a neat arched framework covered with high-transparent plastic film, arranged in separate independent units in the field. It is widely used for vegetable cultivation, flower growing and seedling production. It creates a protected microclimate to support off-season planting, suitable for family farms, planting cooperatives and rural planting bases, delivering an affordable and flexible protected planting option for diversified crop projects.

2.Product Features
It features an independent arched single-span structure with galvanized steel pipes as the main frame. The high-clarity plastic film covering ensures excellent light transmission for crop photosynthesis. The smooth arched shape facilitates rain and snow sliding to reduce surface load. Each greenhouse is an independent unit with separate access, convenient for partition management. The lightweight modular structure is easy to transport and install, and the length and width can be customized according to field conditions and planting plans.

3.Core Functions
The greenhouse shields crops from adverse weather such as frost, heavy rain and strong wind, lowering natural risks. The transparent film traps solar heat inside to raise temperature, enabling off-season cultivation and extending the growing cycle. Ventilation can be realized through side openings to adjust internal temperature and humidity, restrain excessive humidity and reduce crop disease incidence. The independent internal space supports ridge planting, potted flower planting and seedling beds, simplifying daily crop care, irrigation and harvesting work.

4.Competitive Advantages
This single-span arch greenhouse requires low upfront investment and has a short construction cycle compared with multi-span greenhouses. The galvanized steel frame has good rust resistance, and the plastic film is easy to replace with low maintenance cost. Independent separate tunnels effectively block the spread of diseases between plots. It adapts to irregular field land and flexible crop rotation arrangements. We supply complete supporting parts and installation guidance, making it a flexible, cost-effective choice for growers with small-to-medium planting scales.
