Antibacterial Testing

COLORBOND® Permagard® steel has been independently tested in the U.K. in accordance with Japanese Industrial Standard JIS Z 2801:2000, globally the most widely used protocol for testing of antibacterial performance. Tests were conducted against Staphylococcus aureus and Escherichia coli 0157 both of which can be of particular concern to those seeking to maintain good food hygiene standards.

Even after simulated cleaning for 10 years using typical cool room detergents, COLORBOND® Permagard® steel was still found to be highly effective. Peace of mind that's proven to last.

In laboratory testing, an untreated panel and Permagard® (with built-in Microban® protection) were both inocculated with high levels of bacteria. After a 24-hour time period, any remaining bacteria were rinsed off the panels into liquid solutions. These solutions were then incubated in Petri dishes to identify any bacterial presence. As you can see from the photos below, the Petri dish with the solution from the untreated panel, left, has a number of thriving bacterial colonies, whereas the other, right, containing the solution from Permagard®, is almost free from any bacterial growth. This clearly demonstrates the antibacterial efficacy of Permagard® technology.
