Galvalume Plus™ is an aluminum-zinc coated steel that provides extra corrosion protection. The cost of Galvalume Plus™ is slightly more than galvanized steel due to the specialized coating and 40-year warranty.

Galvalume Plus™ offers the best qualities of aluminum-coated (aluminized) and zinc-coated (galvanized) steels. It has barrier corrosion resistance and heat resistance similar to aluminized and good bare edge galvanic protection and forming qualities like galvanized. So, Galvalume Plus™ will resist rust, the elements and fire while providing a sturdy and protective covering.

Galvalume Plus™ offers:

• At least twice the corrosion resistance of traditional galvanized coatings of similar thickness under the same exposure conditions
• Excellent protection at cut edges
• Exceptional heat reflectivity, resulting in lower energy load on buildings and improved interior comfort
• A distinctive appearance, with a smooth, fine spangle and silvery metallic finish
• High temperature resistance

All at no extra cost per square foot!

Currently, uses for Galvalume Plus™ include car mufflers, standing seam roofing, tubing for fences, greenhouses, steel buildings and much more.

Produced for Pioneer Steel by the steel mill ArcelorMittal Dofasco, Galvalume Plus™ offers excellent cost-effectiveness, which we pass on to our customers.

Corrosion Resistance

Galvalume Plus™, by virtue of its combined protection of aluminum and zinc, has at least twice the service life, in most atmospheric environments, of conventional galvanized steel with the same coating thickness.

In a series of exposure tests performed over a 13-year period by Bethlehem Steel, Galvalume Plus™ coated steel was found to outlast galvanized by:

• Four times in exposure tests in a severe marine environment
• Twice as long in a less severe marine location
• Six times longer in industrial environments
• Three times longer in rural situations

High Temperature Performance

Galvalume Plus™ steel resists intermediate and high temperatures far more effectively than galvanized steel.

Specifically, Galvalume Plus™ steel shows no discoloration up to 315°C (600°F) during continuous or intermittent exposure over a prolonged period. Above this temperature, some discoloration does occur and roughening of the surface is possible. Neither this discoloration nor roughening, however, reduces Galvalume Plus's resistance to rust. Galvalume Plus™ maintains its rust-resistance up to 675°C (1250°F.)

Additionally, Galvalume Plus™ has excellent heat reflectivity, up to operating temperatures of about 315°C (600°F.) This heat reflectivity makes a building cooler inside on hot, sunny days.

Painting Galvalume Plus™

Galvalume Plus™ readily accepts most of the paints recommended for galvanized steel. The surface should be dry and free of oil, grease, dirt, dust and other contaminants. No weathering period is necessary.

A paint supplier should be consulted to select the most appropriate painting system and to ensure compatibility of primer and topcoat.
