Nov 29, 2019 · PARTICULARS:GALVALUME®:GALVANIZED:Originated:Galvalume® is a trademark name invented in 1972 by Bethlehem Steel.It is used to describe a metal roofing product. Galvanization used to protect from electric shocks in the 19 th century. It was invented in 1836, and the process of coating steel by dipping it in molten zinc after first cleaning it was used.

- What Is Galvanized Steel?What Is Galvalume Steel?What Is The Process?Galvanized vs. GalvalumeGalvalume® vs. Galvanized Metal Roofing :ABC BlogJun 14, 2016 · While Galvalume ® can initially show signs of corrosion faster than Galvanized, it has a sacrificial property that will prevent the corrosion from growing whereas once corrosion has started on a Galvanized panel, it can continue to corrode until panel integrity is lost.
Galvanize and GalvalumeTM steel should not be combined on the same building elevation because Galvanize will likely exhibit corrosion before Galvalume. As a design practice, when both materials are in contact, always use Galvalume steel downstream from unpainted Galvanized steel, otherwise accelerated corrosion of the Galvanized steel can occur. The Difference Between Galvanized Steel And Galvalume The Difference Between Galvanized Steel And Galvalume Steel 1. Resistance to atmospheric corrosion:GL(galvalume) steel sheet is excellent, while GI(galvanized) steel sheet is good. 2. High temperature oxidation resistance:GL sheet is excellent, and GI is good. 3. Processing performance:GL sheet behaves well, and GI behaves well. 4. Weldability:GL sheet behaves poorly, while GI  What Is The Difference Between Galvanized Corrugated Oct 26, 2020 · Also, Galvalume costs more than galvanized metal roofing but the fact that a Galvalume metal roof will last up to twice as long as a galvanized roof of the same thickness could make up the difference. For these reasons, Galvalume metal roofs are much more popular.
Galvalume ® is more corrosion-resistant than galvanized steel, but because aluminum provides barrier protection instead of galvanic protection, scratches and cut edges are less protected. Galvalume is offered in both bare and pre-coated versions.
