This commercial plastic film greenhouse uses a hot-dip galvanized steel frame and a PE film cover with anti-drip additives. Droplets that form on the inside of ordinary film cut light by 15% to 30% and can damage the crop below; the anti-drip film lets the water run down the sides instead of dripping. The arched roof sheds rain and snow, and roll-up sides move air through the house. It suits farm and vegetable planting at commercial scale.
This commercial plastic film greenhouse covers a farm growing area with a PE film cover on a hot-dip galvanized steel frame. The arched roof sheds rain and snow, and the film holds warmth and diffuses daylight across the crop. Film is the practical choice where a grower needs a large covered area at a workable cost, and the house runs from 8m to 12m spans and 3m to 8m height, with length set to the site.
The frame uses hot-dip galvanized steel pipe. The zinc coating protects the steel in the humid air of a working greenhouse, which keeps the structure sound through years of service. Arched hoops tie each bay together, and the whole frame is assembled from bolted sections on site.
The covering is a PE film with anti-drip additives. Droplets that form on the inside of ordinary film cut light transmission by 15% to 30% and raise the risk of disease, and the drops themselves can damage the plants below. The anti-drip film lets the condensed water run down the sides as a thin layer instead of dripping onto the crop. Film is supplied in rolls from 1m to 22m wide and 0.01mm to 0.2mm thick, in light blue or white.

Film covers a wide area at a lower cost than glass or rigid sheet, which makes it the common choice for commercial vegetable and fruit growing. It is also light, so the frame carries less dead load, and a damaged section can be re-covered without replacing the frame. FAO notes that protected cultivation of this kind extends the growing season and raises yield per square metre in many climates.
The anti-drip film is the part that matters most day to day. Without the additive, condensation gathers into drops that fall on the crop and cut the light reaching it. With it, the water sheets down the sides and leaves the plants dry.
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 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, 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 commercial plastic film greenhouse suits 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.
It is a PE film with additives that stop condensation from forming into drops. Instead the water runs down the sides as a thin layer, which keeps light transmission up and keeps the crop dry.
Film is supplied from 1m to 22m wide and 0.01mm to 0.2mm thick, in light blue or white.
The hot-dip galvanized steel frame is rated for 15 to 20 years under normal growing conditions. The 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.
