Cut Edge Corrosion Repair

Cut edge corrosion repair is a common requirement for commercial buildings, restoring the sheet laps of profiled metal roofs and cladding. If left neglected for too long, corrosion can lead to costly problems regarding health and safety, dilapidations and reputational damage. With our help, you can restore the condition of your commercial property with an advanced coating system designed for repairing and treating cut edge corrosion.

Problem: Cut Edge Corrosion

When profiled metal sheets are cut to fit the bespoke dimensions of a commercial unit, any factory-fitted protection against weathering is lost, leaving edges exposed to the elements. This is a particular problem at the lap joints as capillary held rainwater can begin to penetrate through protective layers, damaging sheets, fixtures and fittings.

Consequently, corrosion at the cut edges is often accelerated, and if left untreated for too long, can develop away from the edge, destroying the weather-sealed lap joint and gutter overhang.

Issues can often be seen in the form of edge peel, discoloration, blistering, spot corrosion and in severe cases, leaks and penetrating water damage. When this occurs, the advice is typically to replace profiled metal sheets, which can be costly, time consuming and disruptive.
