3.The benifits of Galvalume
The primary benefit of Galvalume is corrosion resistance. The addition of aluminum increases the coating's corrosion resistance by a factor of two. If the steel panel is in an area where heavy salt-spray and high humidity predominate, Galvalume provides the most robust protection. Marine environments are hard on most materials. Galvanization alone isn't enough.
Other benefits:
- Galvalume does not add significant weight to the steel, retaining the metal's high strength-to-weight ratio. The coating is every bit as strong and durable as the steel itself. The coating is flexible and will not crack or flake as the sheet metal is bent or formed.
- Steel coated with Galvalume also has superior reflectance in the sunlight. High reflectance reduces heat absorption through the roof panels. With the addition of re-emissive pigments, you will have both energy efficiency and protection from corrosion. With appropriate insulation under the roof, you will reduce cooling costs in the summer and heating costs in the winter. Galvalume also has resistance to high temperatures.
- Besides energy efficiency, Galvalume coated steel costs less than stainless steel and about the same as galvanized steel. Like all steel products, maintenance and repair needs are minimal, providing more cost savings. Unpainted Galvalume can last more than 40 years without appreciable change in appearance. In rural and industrial environments, Galvalume is projected to have a service life of 40 to 60 years.
A galvanized steel roof will start showing its age after 10 to 15 years and has a lifespan of about 15 to 20 years, half that of Galvalume.
- Cut edges in premanufactured panels also have a long-term barrier against rust and corrosion when Galvalume is used as a coating. As long as the coating is not penetrated and the edges remain uncut, the steel will be protected against the elements. Zinc provides galvanic protection for uncut panels.
- Galvalume steel panels can be installed over existing surfaces from asphalt shingles to wood underlayment. It can be used for both structural and architectural roofing needs.
- Steel with Galvalume is a versatile material. It is easily rolled, bent, stamped and fabricated without losing the protection of the coating. There is very little Galvalume won't survive in terms of formability.
Galvalume also enhances fire resistance.
