Care should be taken at all times when handling Corrugated. Packs must be kept dry and stored above ground level, should the sheets become wet separate immediately and individually wipe and place in an area to dry.

ZINCALUME® steel sheeting is compatible with most roofing products. It is NOT recommended to use lead flashing/nails, copper or copper alloy materials with or in run-off situations.

Apex Building Products provides this service, however sheets may be cut using a power saw with a metal cutting blade. COLORBOND® steel sheeting must be cut with the coloured surface facing the ground. Ensure that no hot particles or debris come into contact with the COLORBOND® .

To prevent premature corrosion at the completion of each day ensure the sheeting area is cleared of all debris, including nails, rivets, rags and all cutting or drilling filings.
