New for 2018: ArmourGuard® Steel

Extraordinary levels of corrosion resistance

Lifetime Guarantee

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 hobby polytunnels will be made from high-performing steel with a lifetime guarantee* against corrosion.

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. 

Armour Guard - Unrivalled Corrosion Resistance

Environmentally Friendly

ArmourGuard® even protects the environment by reducing the amount of zinc which is used in the manufacturing process compared to the 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.

*Please note, our lifetime guarantee against corrosion applies to ArmourGuard tubular steel components only (arches, stabilisers, bracings & ridge tubes). Even though all of our brackets and fittings are also fully galvanised, they are not protected with our ArmourGuard® coating and as such do not carry the same guarantee. However, the steel used to manufacture our fittings is 2-3 times thicker than the wall thickness of the steel tube. Our polythene covers and anti-hotspot tape have up to 7 years guarantee against UV degradation. All timber components are pressure treated with Tanalith E™ and as such have a life expectancy of 15-20 years.
