Yes. Additions are relatively easy to make. In addition, the original steel structure will be straight regardless of age, making the job of lining up the extension easier.
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.

Steel's unique ability to actually strengthen as strain increases has made lifesaving engineering advances such as crumple zones and steel safety cages possible.
