This engineered single-tunnel greenhouse is a single-span growing shelter equipped with an independent external shading system. Built with hot-dip galvanized steel framework and plastic film covering, it is specially developed for seedlings, flowers, herbal crops and saplings. It offers reliable crop protection, shading cooling and physical pest isolation. Featuring large inner space and optional irrigation and ventilation modules, it is well-suited for nurseries and commercial growers to carry out stable, protected cultivation for sensitive young plants.

It adopts a classic single-span arched tunnel structure with an extra external shading net supported by separate steel posts. The whole frame uses hot-dip galvanized steel and matched steel connection fittings for anti-corrosion. It comes with side ventilation and insect-proof film cover, and supports optional irrigation and ventilation accessories. It provides spacious interior space for seedling racks. All components are prefabricated, easy to assemble. Dimensions can be customized to match different nursery layouts and planting scales.

This single tunnel greenhouse realizes effective shading and cooling for light-sensitive seedlings, flowers and saplings. The external shading net blocks intense direct sunlight to avoid leaf scorch. Side ventilation regulates air circulation and humidity inside the tunnel. The transparent film and insect net offer physical pest protection, cutting pesticide usage. It shields young plants from heavy rain, strong wind and frost, creating a mild and stable microclimate to boost survival rate and healthy growth of nursery stock.

As a direct factory supplier, we provide competitive factory prices and custom service. The separated external shading design works independently without affecting the main tunnel structure, delivering better cooling effect than built-in shading. It is cost-effective and easy to maintain. We supply complete fittings and clear assembly instructions. Bulk orders are eligible for discounts. This nursery-focused greenhouse is a practical, low-risk solution for global seedling farms, flower bases and herbal planting businesses.
