An agricultural tunnel greenhouse built as a multi-span gable structure on a hot-dip galvanized steel frame. Gable spans run from 8 to 10.8 metres and total height from 4 to 5.3 metres. The same frame accepts PE film, polycarbonate sheet or glass covering, with glass reaching light transmittance above 90 percent. Optional cooling, heating, irrigation, ventilation, fertilization, shading and bench systems can be fitted before delivery. Suitable for cucumber, tomato, leafy vegetables and hydroponic production, and adaptable to uneven terrain.
An agricultural tunnel greenhouse is the practical answer when you need year-round vegetable production at commercial scale. This multi-span structure is built on a hot-dip galvanized steel pipe frame, and the same frame can be configured with PE film, polycarbonate sheet or glass covering - from a low-cost seasonal house to a permanent growing facility. The grooved channel frame reinforces the covering against wind and weather, and the design adapts to varied or complex topography.
The frame is hot-dip galvanized steel pipe, assembled as a gable-roof multi-span structure. Gable spans range from 8 to 10.8 metres and total structure height from 4 to 5.3 metres. Where glass is chosen, 4 mm or 5 mm float glass or 5 mm tempered glass is used, reaching light transmittance above 90 percent. PE film and polycarbonate sheet are available for lower-cost or higher-insulation builds.
The structure can be delivered as a frame-only kit or as a complete growing system. Optional equipment includes cooling and heating systems, irrigation, ventilation, fertilization, shading and benches, fitted according to your crop and local climate.
The house suits fruiting vegetables such as cucumber and tomato, leafy crops and lettuce, and hydroponic production. It performs in all climate conditions and adapts to any type of landscape, which is why it is widely used on sites where the ground is uneven or the plot is irregular. Growers comparing covering materials can look at our tunnel plastic greenhouse for film-only builds, or the vegetable greenhouse series for crop-specific layouts. For protected-cropping practice, USDA publishes extension guidance, and HortiDaily covers greenhouse growing worldwide.
Shipments are packed as metal structures, covering system and installation accessories. We can send our engineers to your site to guide installation when required, and our engineering department prepares the structure drawings and bill of materials for each project. Buyers are welcome to visit the factory for a technical discussion before ordering. You can also compare our tunnel greenhouse range for other span and covering combinations.
The same galvanized steel frame can take PE film, polycarbonate sheet or glass. The glass option uses 4 mm or 5 mm float glass or 5 mm tempered glass and reaches light transmittance above 90 percent. Tell us your crop and local climate and we will recommend the covering that fits.
Yes. The multi-span structure is a simple, effective solution for varied and complex topographic conditions. Because spans are modular, the house can be stepped or split into sections so that each part follows the ground level.
The hot-dip galvanized steel frame is designed for a 15-20 year service life in normal agricultural environments, with a double-sided zinc coating of 200-275 g/m². Film covers are replaced every 3-5 years, while glass and PC panels carry their own manufacturer warranties.
The hot-dip galvanized steel frame carries a 10-year structural warranty covering structural safety, plus a 5-year warranty against corrosion perforation. It is designed for a 15-20 year service life. Film covers carry a 3-5 year UV warranty depending on grade.
Send your growing area, span and length, crop type and local climate. If you already have a layout drawing, that is enough to start. Our engineers then return a quotation with a structure drawing and a bill of materials.
