Details Of Our 12ft Single Span Polytunnels

Our 12ft span polytunnel is great for a larger allotment where you really can grow enough of everything to feed the whole family.

We use 25mm diameter high strength (Z35) galvanised steel tube for the framework of the polytunnel. A four-part hoop helps with easy transportation of the kit, assembled using swaged connections and a central ridge tube. A diagonal brace at each corner ensures stability of the structure. Timber end frames from 75 x 38mm tanalith treated timber for a long lifespan with a double-row of 38 x 19mm battens to secure the polythene. All fixings and fasteners are either galvanised or zinc plated and passivated for protection against corrosion.

The basic kit includes:
• Heavy duty galvanised ground tubes
• Galvanised high-strength steel framework
• Tanalised timber end frames
• Galvanised/electroplated fittings & fasteners
• Polythene tensioning/re-tensioning after sheeting
• Choice of polythene
