MILL FINISH

0.9MM ALUMINIUM

Taranaki Steelformers can provide a range of roofing and cladding profiles and flashings in 0.90mm BMT mill finish aluminium. We can also manufacture 0.90mm arctic white aluminium flashings for our stocked 1200 x 2400mm flatsheets.

Mechanical fasteners, whether rivets or screws, are available in aluminium. Where use of aluminium fasteners is unsuitable (e.g. self-drilling screws), stainless steel is regarded as the best alternative.

In general, direct chemical attack of aluminium only occurs when the PH is below 5 or above 8. Contact with other metals can result in corrosions due to galvanic reactions. Copper, steel, stainless steel and lead will all cause attack of the aluminium alloy. Contact with zinc will cause the zinc to be attacked.

Regular cleaning is required to maintain an unaffected surface for good aesthetic quality in industrial and marine environments. This can be achieved naturally by rain washing but surfaces not adequately washed by rain must be cleaned by water washing and scrubbing with a soft brush to prevent build up of salt, dirt or other airborne deposits. In severe marine locations the washing frequency may be every 4-6 months for surfaces not washed by rain.
