Durability

Designers and tradespeople should be aware of the electrolytic corrosion that can take place when small particles of metal are deposited on another metal, and when the same tools are used with a variety of metals. See Compatibility.

For maximum durability, no water should be allowed to penetrate between stacked panels, strips, profiled sheets or coils during storage and transportation. In high humidity with the simultaneous exclusion of air, white rust will develop on the surface of zinc and zinc coated cladding, and aluminium and copper will also suffer permanent staining. All metals in storage should be kept dry. See Acceptance Of Materials.
