This Venlo PC green house is a multi-span commercial greenhouse covered with polycarbonate hollow sheet. The Venlo roof profile uses a series of small gables across the span, giving a strong structure that sheds rain and snow well. The frame is hot-dip galvanized steel pipe, so it resists rust in humid or coastal air. Covering is 8 mm or 12 mm PC sheet, a double-wall panel with an air gap that insulates better than single film. Spans range from 6.4 to 10.8 metres and heights from 4 to 7.5 metres, set to the site. PC sheet carries high impact strength and holds its light transmission, which suits vegetable growing and seedling work where the climate needs to stay even.
This Venlo PC green house is a multi-span commercial greenhouse built for vegetable production, seedling work and research bases. The Venlo profile uses a series of narrow gables repeated across each span, which is a shape that carries snow and wind loads well and gives the roof a distinctive ridged look. Covering is polycarbonate hollow sheet rather than film or glass, so the house holds heat and resists impact better than a single film cover. It can be built as a small block or rolled out over a large commercial area.
The frame is hot-dip galvanized steel pipe with a double-sided zinc coating, which is the part that decides how the structure holds up in humid and coastal air. The Venlo roof is formed from a row of small gables running the length of each span, supported by columns and trusses. That profile is stiffer than a single wide arch, so the house carries snow load and wind load without additional bracing. Covering is 8 mm or 12 mm polycarbonate hollow sheet set into aluminium profiles, with gutters between spans collecting rain to the ends of the house.

Vegetable growing rewards an even internal climate, and the Venlo profile helps deliver it in two ways. First, the narrow gables create a large ridge volume, so warm air rises away from the crop and vents out through roof windows rather than sitting over the plants. Second, the repeated gables spread snow load across many small ridges instead of one wide roof, which is why the shape is common in regions that see winter snow. PC sheet covering adds insulation on top of that, so night temperatures stay above the point where growth stalls, and the growing window stretches at both ends of the year. Nutrition and irrigation lines, benching and seedling tables can all be fitted inside.
Green house prices move with four things: the area covered, the span and height you choose, the covering material, and the systems fitted inside. A larger area costs more in steel and covering; a taller structure uses longer columns and more material; PC sheet costs more than film but lasts longer; and each added system — cooling, heating, irrigation, benching — carries its own cost. Because every house is built to the site, we quote from your layout rather than a single catalogue figure, and we will break down the price by component so you can see where the money goes and phase the build if you want.
The same structure suits a range of crops. Vegetable growers use it for tomato, pepper, cucumber and leafy greens. Nursery and seedling operations use it for propagation trays, where a stable root-zone temperature gives more even germination. Research and experimental bases use it where conditions must be repeatable from cycle to cycle. Flower growers use it for cut flowers and potted plants that need steady light and insulation. Our main markets are Africa, South Asia, Southeast Asia and the Middle East, and houses are built to the climate of the destination rather than one global specification.
The house ships as a metal frame package with the PC sheet, glazing profiles and installation notes. Steel sections are bundled and the sheet is crated for container loading, and the components are labelled against the assembly drawings so the build follows a clear sequence. Our engineering team supplies drawings and guidance through construction, and where a customer wants support on site we can send engineers to guide installation. Many buyers visit the factory before placing an order, and we welcome that.
The Venlo profile is a roof shape made from a row of narrow gables repeated across each span. It carries snow and wind load well and gives good ridge ventilation, which is why it is common in commercial vegetable and flower production.
Covering is 8 mm or 12 mm polycarbonate hollow sheet, a double-wall panel with an air gap. It insulates better than film, resists impact far better than glass, and holds its light transmission for years.
Spans range from 6.4 to 10.8 metres and structure heights from 4 to 7.5 metres. Send us the site layout and crop plan and we will size the house to fit, and quote by component.
Yes. Cooling pads, exhaust fans, heating, irrigation, shading screens and benching can all be fitted to the same frame, so the house can be equipped as the operation grows.
The galvanized frame is designed for a 15-20 year service life, with a 10 year structure warranty and a 5 year anti-corrosion warranty, and the PC sheet does not need the repeated replacement that film does.
Compare this house with our Venlo green house, the polycarbonate greenhouse and our multi span agricultural greenhouse for other covering and roof options.
