- Enhanced formability
- Total exterior and interior protection
- Unique MAGNAFusion™ weld repair
- Harder more resilient surface
- Environmental sustainability
MAGNAtube® sets a new standard in corrosion-resistant coated steel tube: up to 20 times the corrosion resistance of galvanised tube, the durability of high-strength steel, self-healing anti-corrosion properties, better processing capabilities than post-galvanised tube, plus the added benefit of environmental sustainability.
MAGNAtube®’s evolutionary zinc/aluminium/magnesium coating withstands the most hostile conditions, including alkaline and ammonia rich environments. Furthermore, in exhaustive tests conducted by leading UK test house Rotech Laboratories MAGNAtube® lasted the equivalent of 100 years without significant deterioration.
With unique MAGNAfusion® weld repair, 100% exterior and interior protection is guaranteed. This, together with MAGNAtube®’s tough scratch-resistant surface, offers extreme product longevity.Download the MAGNAtube® brochure
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.
