This commercial tunnel PE film greenhouse pairs a hot dip galvanized steel frame with a PE film cover and climate control at the gable ends. The frame carries the film without posts inside the bay, so beds and paths run clear from end to end. Ventilation and temperature are managed from the ends, which keeps a steady climate along the row through the season. It suits vegetable growing on farms, market gardens and indoor agriculture.
This commercial tunnel PE film greenhouse covers one bay of open ground with a PE film on a hot dip galvanized steel frame, with climate control set at the gable ends. The arch carries the cover without posts inside the bay, so beds, paths and machinery run clear from end to end. Temperature and airflow are managed from the ends, which holds a steady climate along the row through the season. Span runs from 8m to 12m and height from 3m to 8m, with length set to the site.
The frame uses hot dip galvanized steel pipe and formed hoops. The zinc coating resists the humid air of a working greenhouse and keeps the structure sound through years of service. Hoops are tied by purlins and cross braces, and the whole frame is assembled from bolted sections on site without welding.
The covering is a PE film. It holds warmth, spreads light across the row and costs far less than glass or rigid sheet. Because the film is supplied in rolls, a torn cover can be replaced over the existing frame without taking the structure down.

A tunnel is the simple form of a film house. The arch carries the film without posts in the middle of the bay, so beds, paths and machinery run clear from end to end. The covered area warms faster than open ground in spring and holds heat into the evening, which is why it is common for commercial vegetable growing. FAO notes that protected cultivation of this kind extends the growing season and raises yield per square metre in many climates.
Climate control sits at the gable ends. Rolling up the side film or opening an end flap lets warm air leave at the ridge while cooler air enters low down, and an exhaust fan with a cooling pad can be added where summer heat is strong. That flow keeps the temperature even along the row rather than pooling near the middle. HortiDaily covers how commercial growers plan this type of structure.
The frame ships as a knockdown kit of galvanized pipe and hoops, and the film is supplied in rolls. Work follows a set sequence: set the foundation, raise the hoops and purlins, 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, service the fan and clean the cooling pad before the hot months, and inspect the pipe joints for movement. The galvanized frame is rated for 15 to 20 years under normal growing conditions.
This commercial tunnel PE film greenhouse suits vegetable growing, market garden production and indoor agriculture, as well as flower and fruit crops. Because span, length and height are all set to demand, the same frame system fits a small holding or a large estate.

It is a film house built as one bay on a galvanized steel frame, with climate control at the gable ends. It is used for vegetable growing and market garden production.
Airflow is managed from the gable ends. Roll-up side film or an end flap lets warm air out and cool air in, and an exhaust fan with a cooling pad can be added where summer heat is strong.
The hot dip galvanized steel frame is rated for 15 to 20 years under normal growing conditions. The PE film cover is replaced on a shorter cycle.
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.
