This commercial polycarbonate greenhouse uses a hot-dip galvanized steel frame and twin wall PC hollow sheet. The twin wall traps an air layer between two skins, which holds heat better than a single sheet and keeps the crop stable through cold nights. The open floor takes movable benches and seedbeds, so the same house can run seedlings, hydroponic channels or pot plants. Span, length and height are set to the site.
This commercial polycarbonate greenhouse covers a working growing area with twin wall PC sheet on a hot-dip galvanized steel frame. The twin wall sheet has two skins with an air gap between them, which slows heat loss and keeps the crop steadier than a single layer. The clear floor takes movable benches and seedbeds, so the house suits vegetable seedlings, hydroponic channels and pot plants. Spans run from 8m to 12m and total height from 3m to 8m.
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. Trusses tie each bay together, and the whole frame is bolted together on site from a knockdown kit.
The covering is twin wall PC hollow sheet. Two skins with an air gap between them give the sheet its insulation value, and the structure is light enough that the frame carries it without extra bracing. Unlike glass, the sheet does not shatter, so it holds up where hail or rough handling would break a pane.

Twin wall sheet holds heat better than a single layer of film or glass, which cuts the energy needed to keep a house warm through cold nights. It is also lighter than glass, so the frame carries less dead load, and a knock does not shatter it. FAO notes that protected cultivation of this kind extends the growing season and raises yield per square metre in many climates.
The clear floor is the other half of the value. Benches and seedbeds can be moved as the crop changes, so one house can run propagation in spring and finish pot plants later in the year without a rebuild.
The open bay takes movable benches, hydroponic channels and seedbeds. Growers can set the layout to the crop and change it between seasons. HortiDaily covers how commercial growers plan this type of structure and the layouts that work with it.
The frame ships as a knockdown kit of galvanized pipe and connectors, and the sheet is supplied in packs. Assembly follows a set sequence: set the foundation, raise the trusses and bays, then fit the sheet and seals. Our engineers can travel to site to guide installation when required.
Routine work is limited. Check the sheet fixings and seals after storm season, wash the sheet if dust builds up enough to cut light, and inspect the pipe joints for movement. The galvanized frame is rated for 15 to 20 years under normal growing conditions.
This commercial polycarbonate greenhouse suits vegetable seedling production, hydroponic growing, pot plant finishing and general horticultural 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 polycarbonate greenhouse page, or compare it against the glass greenhouse and film greenhouse ranges.
The twin wall sheet resists UV breakdown for many years, and the hot-dip galvanized steel frame is rated for 15 to 20 years under normal growing conditions.
Yes, for heat. Twin wall sheet has two skins with an air gap between them, which slows heat loss and keeps the crop steadier through cold nights than a single layer.
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 open bay takes movable benches, hydroponic channels and seedbeds, and the layout can be changed between crops.
