A gothic arch film greenhouse built on a hot-dip galvanized steel pipe frame with an arch roof, covered by polyethylene film held with aluminium clips. Gable spans run from 5 to 10 metres with a total structure height of 3 or 4 metres. Covering film is 0.08 mm, 0.12 mm or 0.15 mm. Wind load and snow load are both rated at 0.35 kN/m2, and the structure withstands wind speeds of 90 to 100 km/h. Ventilation is by side-wall openings with insect nets and roll-up curtains. The kit ships with an installation manual.
A gothic arch film greenhouse is a tunnel covered with polyethylene film over a hot-dip galvanized steel frame. The arch roof sheds rain and snow without gutters and gives a high, even growing space, which is why this shape is used for vegetable production across temperate regions. Because the frame is bolted rather than welded, the house can be assembled on site with hand tools and taken down again if the plot changes.
The frame is made from hot-dip galvanized steel tube with a zinc coating of 275 g/m², assembled as a non-welded structure with bolts and standard fittings. Gable spans run from 5 to 10 metres, with a total structure height of 3 or 4 metres. Covering film is 0.08 mm, 0.12 mm or 0.15 mm polyethylene, held along the arch and the side walls with aluminium clips. The house is designed to be covered by polyethylene film only.
Both wind load and snow load are rated at 0.35 kN/m², and the structure is tested to withstand wind speeds of 90 to 100 km/h. Recommended layouts are 6 m x 40 m, 8 m x 30 m and 9.6 m x 16 m, with lengths normally supplied in multiples of 4 metres. The 9.6 m version can be fitted with a top vent.
Ventilation is by side-wall openings covered with insect nets and roll-up curtains, operated manually or electrically. To keep the structure serviceable, check the connections at regular intervals and re-tighten any loose wedge immediately. Replace or patch torn film promptly, close all vents and tighten the film line before strong wind, and clear snow as soon as it settles to avoid overloading the arch. Where heavy weather is expected, temporary props under the frame add extra support.
The house suits vegetables such as tomato, cucumber, pepper and leafy crops, and works in all climate conditions on almost any type of ground. Growers who need a taller or wider structure can compare our agricultural tunnel greenhouse, while crop-specific layouts are covered in the greenhouse for tomatoes and tunnel plastic greenhouse ranges. For protected-cropping practice, AIPH represents growers worldwide, and Produce Grower covers commercial vegetable production.
Gable spans of 5, 8, 9.6 or 10 metres are available, with a total height of 3 or 4 metres. Covering film is 0.08 mm, 0.12 mm or 0.15 mm. Recommended layouts are 6 m x 40 m, 8 m x 30 m and 9.6 m x 16 m. Tell us your crop and climate and we will recommend the combination.
Wind load and snow load are both rated at 0.35 kN/m², and the structure is tested to withstand wind speeds of 90 to 100 km/h. In heavy snow, clearing the roof promptly is important, and temporary props can be added under the arches where severe weather is expected.
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.
