20ft (6.10m) Wide Commercial Polytunnels
A spacious, high‑strength structure for serious growing
We supply commercial polytunnels across the entire UK, with free delivery to all mainland locations. For offshore islands, please refer to our delivery page for full details.
The 20ft wide commercial polytunnel offers exceptional internal space, making it an excellent choice for growers who need room to expand. Built from 50.8mm outside diameter galvanised steel, this structure provides long‑term strength and stability in demanding conditions.
Every standard kit includes:
-
Crop bars for added rigidity and overhead storage
-
Foundation tubes for secure installation
-
Anti‑hot‑spot tape to protect and extend the life of your cover
-
Treated timber base rails for a strong, reliable finish
-
SuperTherm cover for excellent insulation and light transmission
-
Before ordering, it’s worth planning how you intend to use your polytunnel. The internal layout plays a major role in workflow, crop rotation, and long‑term efficiency. Useful extras such as additional sliding doors, crop bars, and staging can help you optimise space and create a more productive growing environment.
Choosing the right 20ft wide polytunnel from the start ensures a solid, long‑lasting investment that supports both commercial growth and hobby‑scale production.
