This multi-span PE film greenhouse uses a hot-dip galvanized steel frame with a three-layer compressed film cover. The arched roof sheds rain and snow while the film holds warmth and diffuses daylight across the crop. Spans run from 8m to 12m and total height from 3m to 8m, with length set to the client's site. The structure suits commercial vegetable, fruit and flower cultivation where growers need a large covered area at a practical cost.
This multi-span PE film greenhouse covers a large growing area with a single arched structure. The frame is built from hot-dip galvanized steel pipe, and the cover is a three-layer compressed PE film. Spans run from 8m to 12m and total height from 3m to 8m, so the house can be sized to a commercial vegetable, fruit or flower operation.
The frame uses hot-dip galvanized steel pipe. The zinc coating protects the steel against rust in the humid air of a working greenhouse, which keeps the structure sound through years of service. Arched trusses connect each span, and the whole frame is assembled from bolted sections on site.
The covering is a three-layer compressed PE film. The layers are bonded into one sheet, which raises tear strength and slows the breakdown that sunlight and weather cause on a single-layer film. The film diffuses light as it passes through, so the crop below receives even light rather than hard shadows.

A multi-span frame covers a wide area with fewer side walls than a row of separate tunnels. That layout keeps more of the floor in production and reduces the number of gable ends that lose heat. Growers who need a large cover at a workable cost often choose this shape, and FAO notes that protected cultivation of this kind extends the growing season in many climates.
The three-layer film is also easier to service than glass or rigid sheet. A damaged section can be re-covered without replacing the frame, and the galvanized pipe takes standard fittings that are widely available.
The frame ships as a knockdown kit of galvanized pipe and connectors, and the film is supplied in rolls. Assembly follows a set sequence: set the foundation, raise the arches and trusses, then tension the film over the frame. Our engineers can travel to site to guide installation when required.
Routine work is limited. Check the film tension after storm season, inspect the pipe joints for movement, and wash the film if dust builds up enough to cut light. HortiDaily covers how commercial growers plan this type of structure.
This multi-span film greenhouse suits commercial vegetable and fruit production, flower growing and general farm cover work. Because span, length and height are all set to demand, the same frame system fits a small holding or a large estate. Browse the full range on our film greenhouse page, or compare it against the tunnel greenhouse and glass greenhouse ranges.
The three-layer compressed film is made to resist UV breakdown and mechanical tearing. Service life depends on local sun intensity and wind, and the frame itself is rated for 15 to 20 years under normal growing conditions.
The frame is hot-dip galvanized steel pipe. The zinc coating protects the steel in the humid air of a working greenhouse and holds up through years of service.
Span is available in 8m, 9m, 10m, 11m and 12m. Total height runs from 3m to 8m, and length from 10m to 100m or to your site requirement.
Yes. The structure is used for commercial vegetable, fruit and flower cultivation, and the arched multi-span roof gives enough clear height for trellised crops.
