Corrosion – metal’s kryptonite! It makes your door look ugly, reduces its strength and can even cause injury if someone cuts themselves on it. With a Robust UK product, you won’t have this problem. We’re so confident in the resistance of our products to corrosion, we offer up to 10 years warranty. But why are we so confident?
Magnelis®
We manufacture most of our products using Magnelis® steel. Magnelis® is a flat carbon steel coated on both sides in a metallic chemical composition consisting of 93.5% zinc, 3.5% aluminium and 3% magnesium. This composition provides optimum corrosion resistance – up to 3x better resistance than galvanised steel. Magnelis® also has ‘self-healing’ properties on cut edges and scratches/perforations to the external structure. Over time, when exposed to the environment Magnelis® forms a dense zinc-based protective film over itself. This film will eventually cover cut edges and scratches that expose naked steel underneath, preventing oxidisation and thus, preventing rust and corrosion. This ensures full protection of the entire sheet of steel.
The extended durability means that Magnelis® is a highly cost-effective alternative to galvanised steel, due to the reduced maintenance required and no need for post painting. This makes Magnelis® steel a pioneer in corrosion resistance, being able to withstand some of the harshest environments.

Door Finish
Magnelis® products are designed to be unfinished, as the protective alloy film is enough to prevent corrosion. However, we add our own PPC finish to our doors to ensure extra protection from the elements and to ensure the door meets the aesthetic requirements of the client. All our products are available in a wide range of finishes, using our in-house paint facilities at our Longton factory. We have 50 standard RAL colours available, along with a non-standard colour range, PVC laminate and stainless steel finishes – all available on request. We also offer a woodgrain-effect PVC laminate for applications that require an authentic timber look but the durability of a steel door.
Choosing the right finish for your door is just as important as using Magnelis® steel. The door finish will form an extra barrier between the metal and the outside elements, protecting the metal hidden underneath. This helps to block out the threat of the elements, preventing the steel from corroding and rusting through oxidisation. Also, who doesn’t love a bit of colour? We also offer on-site paint repairs to ensure your door remains fully protected from the elements.
