Northern Polytunnels are now offering a lifetime guarantee on our range of hobby polytunnels

Since 1969, Northern Polytunnels have been designing world-class polytunnels for commercial growers and nurseries all over the world. During that time, we have had the pleasure of working with some of the biggest names in the industry and have constantly been improving our design to make our polytunnels the highest specification they can be. As of 2018, all Northern Polytunnels steel-hooped frameworks will be manufactured using our newly developed ArmourGuard® steel. ArmourGuard® is Northern Polytunnel’s newly developed high-endurance tube, combining extraordinary levels of corrosion resistance with the durability of high strength steel. ArmourGuard® offers up to 20 times the corrosion resistance of galvanised tube thanks to its revolutionary zinc, aluminium and magnesium coating. 

ArmourGuard® is designed not just to survive in the most hostile environments but also to offer extreme longevity. In exhaustive tests carried out by Rotech Laboratories, one of the UK’s leading test houses, ArmourGuard® endured the equivalent of 100 years’ exposure to the harshest elements without undue deterioration. 

By extending the life of our polytunnel components, ArmourGuard® also helps to protect the environment by reducing our reliance on manufacturing resources and helping to contribute to lower amounts of zinc in the atmosphere.

As a business, we think it’s important to work towards reducing the impact that we have on the environment. ArmourGuard® helps to increase the sustainability of our polytunnels by reducing their reliance on manufacturing resources and resource-wasting maintenance.

With added innovations to make our hobby polytunnels quicker and easier to build, along with unrivalled strength and durability expected from our commercial structures; it should come as no surprise that our polytunnel framework now comes with a lifetime guarantee.

We offer a range of polytunnels, from 8ft to 16ft wide, that are both easy to assemble and resistant to even extreme weather conditions. Shop the range here:
