Cement sheet

Asbestos cement sheet (also known as fibrocement or AC sheet) may contain chrysotile, amosite and/or crocidolite. Use of crocidolite ceased in the late 1960's. Later cement sheet products contained only chrysotile until its use ceased in the early to mid 1980's.

Most commonly found as flat or corrugated sheeting, available profiles included shadowline, highline, coverline, ribline and striated.

Wide range of applications including: eaves, roofing sheets, roof shingles, external and internal wall cladding, ceilings, underlay, guttering, downpipes, conduits, flues, water pipes, fences, ceramic tile backing, fish ponds, planter boxes, pots, phone box tops, switchboard linings, fire place linings, shower recesses, arc chutes, arc shields, underground pits.
