For the manufacturing of silencers, we often use pregalvanized sheet metal. Some other components get hot dip galvanization after manufacturing. After galvanization a protective layer will develop over some time period. This will keep the base material from corrosion for many years. On the surface of galvanized components sometimes areas with white storage stain will come up. This is a change of the visual apperance which will be washed off after some time in ambient condition. In the end the appearance will come back to an evenly patina. White storage stain can not be claimed against the galavanizing shops. Therefore we also do not take over any liabilities in case white storage stain shows up. The tendency for white storage stain development is specially there on new galvanization coatings and is supported by air humidity or humidity in tight layers. This situation we can find in galvanized silencers, where Mineralwool covered by glass tissue is facing direct the galvanized perforated sheet. In most applications also the silencer splitters are more or less in direct contact with the ambient air flow which always has a natural moisture content. Please note our storage and handling instructions to keep the development of white storage stain as low as possible.
