Industrial cladding sheets have become ever more popular in recent years being used on a number of areas around commercial properties. Many commercial properties are now using them as they are much more sustainable compared to other building materials, industries such as Medical centres, Warehouses, Hospitals, Retail and Offices are now using a range of cladding materials in both interior and exteriors. However, not many people know what cut edge corrosion is and why it happens, so read on to find out more.

How does cut edge corrosion form?

Before cladding became popular for commercial use, it was predominantly used for barns and large sheds. With ever-changing architectural trends, cladding has become more popular but has also had to adapt to the different styles of buildings and demands of how the customer wants it to look. Cladding materials have had to become stronger over time to make sure it meets health and safety regulations within a range of industries. In most recent years it is more apparent than ever that cladding is now being used as more of an aesthetical feature to help improve the overall look of the building.

Cut edge corrosion

When cladding panels are originally manufactured, they are usually coating in a specialist sheet of plastic coating. The plastic coating applied is often put in place to prevent the underlying metal from corrosion due to the constant exposure to natural elements. It can also help with the appearance of the cladding as it seals in colour.

Corrosion becomes more visible over time, if you are located in an area where it is more common to experience severe weather then you might notice this much sooner then others. Around 60% of property owners have cut edge corrosion and are entirely unaware that it is in fact damage from weather.

When you first have the cladding panels applied the exterior of your commercial property, you will often find that they are not the right size and need cutting to ensure they are a perfect fit. Once the cladding panel is cut, the protective plastic seal is also cut and does not get reapplied at any point leaving the edges exposed to the elements. Over time the steel part of the cladding panels become more and more exposed to oxygen in the air. Over the course of a couple of years the mixture of oxygen, water and other pollutants which make the ages more likely to erode. Another, downfall of the corrosions is that it will slowly start to make the plastic coating peel away. Meaning your cladding panels become more and more exposed over time.

Unfortunately, as well as your cladding panels, guttering can also be affected by cut edge corrosion. If the guttering is not cleared correctly, it can mean the guttering remains damp. If your guttering is not seen to regularly, it can cause it to become damaged, which can also be a health and safety hazard as it has the potential to fall. We highly recommend booking in for guttering cleaning, to ensure your gutters are clean and safe.
