Galvalume Steel
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.
BENEFITS
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.
OPTIONS
Coating Thickness
Available in AZ35, AZ50 and AZ55 coating weights.
Chemical Treatment
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.
Resin Coating
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.
END-USE APPLICATIONS
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.
