This multi span film greenhouse uses a hot galvanized steel framework with 275 g/m2 zinc coating, giving 10 to 15 years of anti rust service. The covering is white black and white polyethylene film, and the double layer keeps heat in through cold nights. Spans are recommended at 8 m, 9.6 m and 11.8 m or customised to your site, with shoulder heights of 3 m to 5 m and bays set by local wind speed, usually 4 m. The structure suits blueberry, vegetables and nursery stock on open ground, and the arch profile sheds rain well. Assembly is bolted from a pre fabricated kit.
Blueberry and vegetable growers who need wide, economical cover usually choose a film house over glass. This multi span galvanized film greenhouse gives a large clear span at a fraction of the cost, and the double layer polyethylene cover holds warmth on cold nights. The frame is hot galvanized steel with a 275 g/m2 zinc coating, so it resists rust for 10 to 15 years with normal use.
The framework is fabricated from hot galvanized steel, coated inside and out with 275 g/m2 of zinc. That coating protects cut ends and bolt holes, which are the first places to rust on untreated steel. The cover is white black and white polyethylene film, fitted as a double layer to reduce heat loss overnight. Spans are recommended at 8 m, 9.6 m and 11.8 m, or customised to the site, with shoulder heights between 3 m and 5 m. Bays are set by local wind speed and typically run 4 m. The arch profile sheds rain and snow without flat spots. Growers planning protected fruit programmes often follow extension guidance such as that published by Michigan State University horticulture, and trade reporting on FreshPlaza.
The greenhouse arrives as a pre fabricated kit with numbered frame sections, film and fittings. Assembly is bolted, so no field welding is needed and a trained crew can raise a standard bay in a predictable time. Maintenance is mostly about the cover: inspect the film for tears before each season, keep the double layer properly tensioned so it insulates well, and check that gutters and drainage stay clear. Galvanized steel needs no repainting under normal use.
These houses suit blueberry production, where the film shortens the growing cycle and protects fruit from rain and birds. Vegetable growers use the same span for tomatoes, peppers and leafy crops, and nursery operations use the covered space for propagation and hardening off. Because the cover costs far less than glass, large blocks can be built economically. Compare our full multi span greenhouse range and the galvanized steel frame film greenhouse, or review our agricultural multi span greenhouse options for larger blocks.
Two layers of film trap an insulating air gap, which cuts overnight heat loss and raises the minimum temperature inside. That matters most for blueberry and early vegetable crops in cold climates.
With a 275 g/m2 zinc coating and normal use, the frame resists rust for 10 to 15 years. Touching up any scratches in the coating will extend that further.
Yes. We recommend 8 m, 9.6 m and 11.8 m as standard, but spans can be built to your site plan. Send your required width, length and shoulder height and we will confirm the layout.
Blueberry is the most common use, along with tomatoes, peppers, leafy vegetables and nursery stock. The wide clear span also suits small mechanised work such as trolleys and light tractors.
Send your span, length, shoulder height and local wind and snow loads, plus your target crop. We reply with a layout drawing and a full quotation covering frame, film, ventilation and fittings.
