GalvalumeTM steel is used for industrial & commercial roofing, agricultural buildings, light steel framing, construction tubular, and pre-engineered buildings.
GalvalumeTM
- GalvalumeTM Steel is produced by the continuous hot dip coating process, in which the steel strip is fed through a bath of molten aluminum-zinc alloy. GalvalumeTM steel sheet combines the best qualities of aluminum and zinc offering superior corrosion resistance and heat reflectivity. The smooth, silvery metallic spangle appearance makes it attractive in unpainted applications. It is also available in pre-painted form in a number of different paint systems and can be readily post-painted in the field or at the fabricating plant.
Galvalume PlusTM
- Galvalume PlusTM is a coated steel sheet that combines the excellent corrosion resistance of a GalvalumeTM coating with a clear, organic surface treatment. The resin coating is applied over both sides of the GalvalumeTM sheet as a final protective layer. The result is an enhanced product with superior attributes for architects, product manufacturers, installers and building owners. Galvalume PlusTM can be roll formed dry with no lubricants and delivered to the jobsite dry with no oil on the surface. It resists fingerprinting during handling and installation, maintaining its "brand new" appearance longer.

Hot rolled
All flat rolled steel products at ArcelorMittal Dofasco start by rolling heated slabs from steelmaking through the hot strip mill to the ordered hot roll dimensions with the specified chemistry and mechanical property range.
Cold rolled
ArcelorMittal Dofasco produces a variety of cold rolled products consisting of conventional, full hard, weathering, enameling and electrical steels.
Galvanized
ArcelorMittal Dofasco produces a variety of hot dip galvanized (zinc coated) steel products using hot roll or full hard cold roll strip depending on ordered thickness. The steel substrate of coated coils can be selected from different steel qualities, from mild steels to advanced high strength steels, and coated with different coating thickness’ depending on the end use requirements.
Tinplate Products
ArcelorMittal Dofasco produces a variety of Tin Plate products. These products are cold rolled once or twice and continuously annealed to produce Black Plate. The Black Plate can then be coated with a thin layer of tin or chromium through electrolytic deposition.
