The passivated coating that develops on stainless steel’s surface provides good corrosion resistance; however, it has the drawback of being susceptible to salt corrosion. The protective coating of BRD’s surface protects it against salt damage. BRD is significantly superior in situations where “red rust resistance” is critical.
Aluminum also offers a corrosion-resistant quality from the formed protective film on its surface. Steel sheet with a layer of 55% aluminum also displays equal efficacy. The downside is that alkali resistance is a problem for aluminum.
Steel sheets erode fast in an alkaline environment with a high pH, while BRD is less susceptible to corrosion, remains almost intact, and maintains its excellent quality in alkaline settings.Ordinary metallic-coated steel sheets exhibit fast corrosion over a duration of 100 hours when immersed in an alkaline solution with a strong pH level of 12.5. On the other hand, BRD remains stable and maintains minimal corrosion after 300 hours.
