Cor-spanThe Cor-Span X panel profile has been around for many years. The Cor-Span profile used to be the main panel used in any steel sheeting application. Though not as popular nowadays, this panel can be used to make your building stand out from the rest. The main ribs are 7/8" high with a continuous wave pattern. The panel screws are also partially hidden by the nature of the profile. These panels are manufactured in 26ga steel with yield strength of 80,000 psi. The Cor-span panel is a great alternative to the Superspan panel and just as cost effective. This panel is available in over 20 different colors. The base metal is galvalume, which is a zinc-aluminum coating that provides excellent corrosion resistance.
