Cascadia Metals offers a wide selection of 55% Aluminium-Zinc Alloy Coated Steel products. 55% Aluminium-Zinc Alloy Coated Steel is cold-rolled carbon steel with a metallic coating composed of Aluminium (55%), Zinc (43.4%) and Silicon (1.6%). The generic product reference is 55% Aluminium-Zinc Alloy Coated Steel, although there are trademarked names for the same product.
55% Aluminium-Zinc Alloy Coated Steel’s coating out-performs galvanized steel at a rate of 2 – 6 times. 55% Aluminium-Zinc Alloy Coated Steel is a favourite of architects due to its eye-catching aesthetics, long-lasting performance, design flexibility and the vast number of potential end-use applications.
Durability – protected from corrosion in most end-use applications
Severe Conditions – superior in most atmospheric conditions
Sustainability – 100% recyclable with long service life
Flexibility – can be formed into a wide variety of end-use applications
Low Maintenance – easy to clean surface that is virtually maintenance free
Our 55% Aluminium-Zinc Alloy Coated Steel meets ASTM A792 requirements.
So you can rest assured our product will meet all standard specifications per ASTM.
Available in AZ35, AZ50 and AZ55 coating weights.
A chemical surface treatment is available which consists of a thin, invisible, corrosion inhibiting, inorganic, chemical film applied on both sides of the metallic coated surface. This film is applied at the metallic coating line by dipping the steel strip into a solution of corrosion inhibiting chemicals. The chemically treated surface is much more resistant to staining that typically occurs in humid conditions during storage or transportation.
A resin coating is also available on our 55% Aluminium-Zinc Alloy Coated Steel. This water-based resin coating is formulated to resist finger printing and scuffing during product handling, improves resistance to wet-stack stains occurring during transport and storage, and virtually eliminates the need for roll forming lubricants.
55% Aluminium-Zinc Alloy Coated Steel products are found in a wide variety of applications requiring long-term, maintenance free corrosion protection. End-use applications well suited for 55% Aluminium-Zinc Alloy Coated Steel include roofing and wall panel applications, metal buildings, fascia and other architectural applications.
