In recent years, industrial cladding sheets are used on a variety of commercial grade buildings such as Hospitals, Medical Centres, Warehouses, Retail Units and any other type of commercial building that is exposed to a lot of harsh weather.
A lot of facilities managers and business owners find themselves asking what is cut edge corrosion?
However, in the early days of commercial cladding installations, they were predominantly used for barns and sheds. Over the years, this material has had to evolve with the changing architectural trends and become stronger as a result.
When the cladding panels are being manufactured, the sheeting is coated in plastic. It may seem a little strange, but this plastic protects any underlying metal from corrosion and helps add to its appearance.
The corrosion becomes visible when the cladding sheets are exposed to the elements without any protection. So what do you do when you discover a panel layered with corrosion?
How to Fix Corroded Panels
The cladding sheets in question need to be completely assessed by a qualified contractor. They will be able to identify any corrosion and any causes.
Alternatively, if you have a full-time facilities manager on site, he or she can assess the panels and note down any causes in their reports.
2. Identify Severe Areas
Being realistic with your sheets is important. Your chosen contractor will be able to help you out here. You need to be able to determine the parts of the sheeting that are not salvageable. It’s better to be realistic than optimistic at this point.
3. Remove Moss and Grime
Once the severely damaged sheets have been identified and removed, you will need to remove any existing moss, dirt, grime and mould from the area.
Any cladding repair contractor worth their salt will be able to do this quickly and with little fuss. They will also look to remove any flaking paint that remains mechanically.
4. Start Fixing
Once the dirt has been withdrawn a team will begin doing what they can to repair the cladding and corroded metal sheets. Any uneven panels with be sanded back (some prefer to use the term feathered) to reduce the chances of any additional damages.
The cladding sheets will then need to be thoroughly cleaned again. This helps to remove any final pieces of grime that could still be present in the roofing structure.
As the repairs are being completed, many significant gaps may start to appear in the sheets. The best way to resolve this issue is to use a sealant gun to close the spaces as quickly as possible.
Once the cladding has been reinstalled and the damaged sheets removed, the cladded area will need to be re-sprayed. This is to help match your buildings existing colour schemes and provide a protective coating. This will prevent future damages to your roofing panels and save you a considerable amount of money in future repairs.
Cladding panels are vulnerable to corrosion when they are fresh from the manufacturer’s warehouse. This is due to the protective coating being non-existent at this stage.
It is important to have a professional contractor spray the sheets as soon as possible to prevent future corrosion.
