corrender Outdoor: Excellent test results

In order to demonstrate the performance of corrender under natural conditions, corrender samples and samples of conventionally galvanized steel were exposed in 14 different locations worldwide. These exposure tests were conducted in collaboration with the French Corrosion Institute to ensure that differing temperatures, precipitation volumes, humidity and pollution levels (SO2 und NO2) and distances to the ocean were taken into due consideration.

65% higher level of protection

After one year, corrender loses a significantly smaller amount of mass at each of the worldwide locations and thus higher protection against corrosion than conventionally galvanized steel strip. An average improvement of 65% was determined across all the locations, whereas the protection level was increased by more than 80% at some of the places. The increased level of protection was not lower than 40% at any of the locations.

Increased protection of cut edges

Based on its alloy composition, the electrolytic protective effect of corrender is substantially higher than that of conventionally galvanized steel strip. This allows a higher level of protection on the cut edges, even when the protective layer thickness is reduced from Z 275 g/m2 to ZM 120 g/m2.
