Metal Stairs ~ these can be produced in cast iron, mild steel or
aluminium alloy for use as escape stairs or for internal
accommodation stairs. Most escape stairs are fabricated from cast
iron or mild steel and must comply with the Building Regulation
requirements for stairs in general and fire escape stairs in
particular. Most metal stairs are purpose made and therefore tend
to cost more than comparable concrete stairs. Their main
advantage is the elimination of the need for formwork whilst the
main disadvantage is the regular maintenance in the form of
painting required for cast iron and mild steel stairs.
