BlueScope Steel recommend 'cold cutting' coated steel products. If this recommendation is followed, these products will 'self heal', that is, the zinc in the surrounding coating will protect the newly exposed edge. How does this happen? In the presence of moisture, a reaction occurs between the zinc and the steel which results in galvanic protection of the exposed steel, thereby inhibiting corrosion. The degree of protection depends on the thickness of the coating (the amount of zinc), and this is taken into account when Building Standards are formulated.
