Galvalume Steel
Galvalume Steel is offered in a wide selection of 55% Aluminum-Zinc Alloy Coated Steel products. 55% Aluminum-Zinc Alloy Coated Steel is cold-rolled carbon steel with a metallic coating composed of Aluminum (55%), Zinc (43.4%) and Silicon (1.6%). The generic product reference is 55% Aluminum-Zinc Alloy Coated Steel, although there are trademarked names for the same product.
55% Aluminum-Zinc Alloy Coated Steel’s coating out-performs galvanized steel at a rate of 2 – 6 times. 55% Aluminum-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.
Benifits
Durability
The aluminum-zinc metallic coating forms a permanently bonded, tough, sacrificial coating that protects the steel from corrosion in most end-use applications.Severe Conditions
55% Aluminum-Zinc Alloy Coated Steel has superior long-term corrosion resistance in most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum.Sustainability
55% Aluminum-Zinc Alloy Coated Steel is 100% recyclable (can be melted back down for reuse) at the end of life which means less construction product going in landfills. In addition, its long service-life means the product will last longer without need for replacement.Flexibility
Can be formed into a wide variety of end-use applications without sacrifice to the metallic coating. This design flexibility allows architects to accomplish the look they desire for any project.Low Maintenance
Provides an easy to clean surface that is virtually maintenance free.ASTM Specifications
ASTM Designation A792 outlines the general requirements for hot-dipped 55% Aluminum-Zinc Alloy Coated Steel. Included in this specification are steel chemistry requirements, typical mechanical properties of various metallurgical grades, and the coating weight requirements for the different coating designations.

Options
Coating Thickness
Coating thickness is measured as the coating weight in ounces per square foot. For example, a coating designation of AZ50 specifies there is a minimum coating weight of 0.50 ounces per square foot on both sides of the sheet. The most common coating thicknesses are AZ35, AZ50 and AZ55.
Surface Treatments
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 “white rust” – the corrosion of zinc that typically occurs in humid conditions during storage or transportation.
Resin Coating
A resin coating is also available on our 55% Aluminum-Zinc Alloy Coated Steel. This water-based resin coating is applied to both sides of the strip regardless of whether chemical-treatment is part of the resin package or pre-applied. The 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% Aluminum-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% Aluminum-Zinc Alloy Coated Steel include roofing and wall panel applications, metal buildings, fascia and other architectural applications.
