Steels suitable for galvanizing - Nordic Galvanizers

Important information about cold rolled steels. Ann ealing steel with a silicon content in the range 0,15-0,21 weight percent can easily decrease the free silicon content so it falls within the Sandelin range. The steel is then very reactive and get a thick, brittle coating with poor adherence to the steel surface.
