New for 2018: ArmourGuard® Steel

Extraordinary levels of corrosion resistance

Strength and durability is the cornerstone of our business and we don't believe in cheap, flimsy materials. That's why all of our products are designed and manufactured in the UK using the highest quality materials. As of January 2018, all of our commercial polytunnels will be made from high-performing steel.

ArmourGuard® is Northern Polytunnels' 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 pre-galvanised steel tube thanks to its revolutionary combined zinc, aluminium and magnesium coating. 

100 Years Exposure without Deterioration

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.

The image above shows the effect of 3,000 hours of salt spray testing on three steel tubes. This represents the equivalent of 100 years. From left to right: pre-galvanised steel, hot-dipped galvanised steel, and finally, ArmourGuard® coated steel. 

Environmentally Friendly

ArmourGuard® even protects the environment by reducing the amount of zinc which is used in the manufacturing process compared to fully galvanised steel tube. By extending the product life we are also reducing the overall long-term consumption of steel and the related energy inputs.
