Upgrade your Steel!
If your site is particularly exposed with strong prevailing winds, you can increase the steel size of your hoops for your polytunnel. Upgrade the hoop size from 35mm to 45mm to give you extra stability and peace of mind.
All steel is high tensile galvanised Z35 Steel.
Note: This steel upgrade applies only to our structure 12-14ft wide x 16ft long and does not apply to any other product.
