Do not allow any metals other than aluminium, galvanised steel, ZINCALUME® steel or zinc to come into direct contact with COLORBOND® steel. Any direct contact between any other metals (eg. copper and lead) and COLORBOND® steel can result in corrosion. Especially take note of the following: • Copper pipes and lead flashing should not come in direct contact with either ZINCALUME® steel or COLORBOND® steel. If the building design is such that water will flow from lead flashing onto ZINCALUME® steel or COLORBOND® steel, then the flashing should be painted. • Water from copper pipes should not be directed onto COLORBOND® steel or ZINCALUME® steel. • Stainless steel fixings and fixings containing copper should also not be used with ZINCALUME® steel or COLORBOND® steel. • Fasteners conforming to AS3566 Class 3 or 4 are acceptable depending on the location of the product. If you have any questions, ask your supplier or contact us. This information is intended as a guide only.
