The original cut edge corrosion treatment
As the original pioneer of the revolutionary cut edge corrosion treatment, Edgecoat, we know a thing or two about repairing profiled metal roofs. Designed for application to the cut edge of metal profiled roof sheets, our product has been refined over the years to provide long-lasting results. So, what makes Edgecoat so different from other products on the market?
The development of Giromax® Edgecoat starts with our late founder, Roy Emmett. An innovative engineer, Roy had a proven background when it came to finding solutions for different problems. Early on in his career, while working for a leading automotive company, Roy invented an efficient new production conveyor.
By the 1980s, Roy had established a pipe-fitting firm, distributing corrosion coatings, and this was where his knowledge of cut edge corrosion began. Roy was introduced to a specialist coating firm with a single yet prestigious customer, British Steel. He subsequently launched this specialist coating to a mass market, developing innovative formulas to treat cut edge steel. As a result, the highly niche, cut edge corrosion market was born.

The problem with cut edge corrosion
Industrial roofing systems are prone to corrosion at the cut edge of metal profiled sheets. Steel roofing sheets are coated are coated with Plastisol, which provides protection from the damaging effects of weather and UV rays. This durable finish also gives the metal sheets a pleasing aesthetic appearance. At the point where the roof sheets are cut, this can leave the cut edge exposed to air and water. Over time, this oxidises and creates rust, which then weakens the roof integrity.
When a building heats up and cools down, this can cause the metal roofing sheets to expand and contract. As a result, the coating layers around the cut edge can separate slightly away from the metal, resulting in water ingress with capillary action. Damage starts to creep in under the coating, which compromises the metal sheet. At this stage, it’s important to repair the cut edge corrosion to avoid the damage spreading to a greater area.
Corrosion around the lap joints can also cause issues, as the capillary held rainwater can start to penetrate through the protective layers. If left untreated, corrosion at the cut edges can be accelerated, destroying the weather-sealed lap joint and gutter overhang.
When left untreated, cut edge corrosion can be seen in the form of spot corrosion, edge peel, blistering and discoloration. Over time, this could undermine the entire roof’s integrity, leading to serious and costly water leaks. This in turn can cause business disruption if the whole roof needs to be replaced and workers have to be relocated.
Giromax cut edge corrosion treatment
Although strong and robust, metal roofing systems can deteriorate quickly if any cut edge corrosion is left untreated. As the corrosion happens just below the surface coating, it can be hard to spot. It’s important to inspect industrial roofing systems regularly. If cut edge corrosion is detected, however, it can be a simple job to treat.
Giromax® Edgecoat is an innovative, cut edge corrosion treatment. Moisture tolerant, this revolutionary coating system can be applied in damp conditions. The formula treats the top and reverse sides of the cut edges of a metal roofing sheet. Using laminar flake technology and BBA-certified, Giromax® Edgecoat is a cost-effective, weatherproof formula that comes with a 15-year guarantee.
Ideal for cost-effective repairs and dilapidations, Giromax® Edgecoat can be used on metal roofs, cladding and gutters. This cut edge corrosion treatment provides protection and flexibility for external joints. The system is applied using a two-stage process.
When it comes to cut edge corrosion, Giromax® is the original leader in the market. Our continual innovations in roof coating technology have led to a longstanding, loyal client base of surveyors and contractors that spans decades.
Correct application our products enables you to obtain the Giromax Guarantee, giving your client peace of mind when it comes to the longevity of their roofing system. Our Technical Service Managers are on hand to advise you at every stage of the process, so you can focus on delivering your project on time and on budget.
