Durasteel – Steel faced asbestos cement sandwich panel
Description
Perforated steel sheets on both faces with an AC sheet inner core. May be referenced as Durasteel laminate.
Imported product from Durasteel Ltd (UK), produced since 1934. The use of AC is said to have ceased in 1978 and replaced with a fibre cement sheet.
In 1980 the manufacturer was taken over and renamed Cape Durasteel Limited. Product sold under this name is non-ACM.
Uses include fire door outer panelling, as fire break panels above doorway architraves, as protective structural layer around high voltage electrical units.
May also have been used to achieve dual fire and security rating, due to steel reinforcing.
May be painted.
