Steel frame construction

The steel frame of the State Insurance Tower (known as the Bank of New Zealand Tower up until 1998) is seen in this view looking down Lambton Quay, Wellington, in 1979. Steel frames in multi-storey buildings must be encased in concrete or covered by fireproof materials so that their designed bearing capacity is not reduced in the event of a fire.
