Cladding has advanced over recent years and has been the preferred choice for commercial and industrial buildings such as schools, museums, hospitals and warehouses. Now known as profiled (low-carbon) steel cladding, these technological advances have enabled manufacturers to reduce prices and offer various coating materials to protect and enhance appearance, such as the Seamsil sealant application. Despite these advances, steel cladding is not without its issues; a common example being cut edge corrosion. Generally, steel tends to corrode with the presence of oxygen and this corrosion is sped-up when water and pollutants are added to the mix. To protect steel from this form of cladding corrosion, manufacturers will apply a protective layer of Seamsil application to seal the edges that have come away from the cladding; with the option to apply a patterned coating of plastic or PVC to provide extra protection against corrosion. The protected steel sheets, which are large by length, are then cut into more convenient sizes for sale which results in unprotected cut ends. Therefore, cut edge corrosion appears inescapable, so something has to be done to minimise the effect so the lifespan of the steel cladding can be extended. This early corrosion can be reduced with selected sheeting that is manufactured specifically to minimise the risk of edge corrosion. Sheets made with zinc-aluminium alloy have lower rates of corrosion and the steel will last longer than sheets coated in pure zinc. Applying paint to the visible edges may provide a solution as long as it is looked after and re-painted accordingly. If cladding sheets show signs of cut edge corrosion and are not repaired or replaced, further damage will be imminent. Signs of rust and peel back are definite indications and in more severe cases, seeping water.
