- Environmental sustainability
MAGNAtube® is Top Tubes’ newly developed high- endurance tube, combining extraordinary levels of corrosion resistance with the durability of high strength steel – and offering up to 20 times the corrosion resistance of galvanised tube thanks to its revolutionary zinc, aluminium and magnesium coating.
MAGNAtube® 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, MAGNAtube® endured the equivalent of 100 years’ exposure to the harshest elements without undue deterioration.
Total exterior and interior surface protection is ensured, even down to the unique MAGNAfusion™ weld repair. And MAGNAtube® offers improved manipulation capabilities over galvanised tube.
MAGNAtube® even protects the environment by reducing the amount of zinc in manufacture compared to galvanised tube and by extending product life.
The Simonkolleite Factor
The magnesium content within the coating forms an additional highly stable layer called Simonkolleite which completes a triple level of unrivalled protection both outside and inside the tube. Even cut edges are protected by the spreading of this Simonkolleite layer.

MAGNAfusion™ weld repair
Top Tubes’ unique MAGNAfusion™ weld repair, carefully formulated to precisely match the characteristics of the rest of the coating, ensures consistent exterior and interior surface protection, resulting in the same level of corrosion resistance throughout.
