Introduction
Multi Span PC Sheet Greenhouse is a multi-purpose greenhouse structure with vertical sides and interconnected gutters which can be used for a variety of crops. Due to the high roof, it is easier to control the temperature.
Polycarbonate Panels are the jack-of-all-trades for plastic sheets. Durable, versatile, and easy to work with, polycarbonate panels can be used in hundreds of custom projects. Patio and pergola coverings, skylights, custom greenhouses and other structures. We've even had customers use them for solar cookers and biomass generators. There is no limit to their use.
Polycarbonate panels are less expensive in comparison to almost any other plastic sheet, and they are easier to work with than glass or acrylic. Use polycarbonate panels for your next custom project.
We offer various sizes and can manufacture to specification as well. The structures are either naturally ventilated with roof and side curtains, or have a pad and fan cooling system with Envirowatch digital control boards.
In the Multispan greenhouse range we build 6.4m, 8m, 9.6m and10m, 12m structures,
We build Multispan greenhouses only up to 500m² in size. Anything bigger is more affordable and quicker to import. We are in a joint venture with Vegtech and also market their Multispan greenhouses.
We use only the best quality pre-galvanized piping for our structures, and all our piping and channels are 2mm plus thick. All the parts on our structures are hot dipped galvanized after welding.
