With an opportunity to choose from three distinct Maxima profiles: Maxima, Maxima 1.5 and Maxima ADV, McElroy’s Maxima family of products represents the industry’s broadest selection of vertical leg standing seam systems. In order to meet the varying needs of architects and contractors, each offers unique performance characteristics that enable users to match a Maxima panel to specific aesthetic and performance specifications.
In some cases, Maxima panels can be produced on-site by McElroy factory technicians. Maxima 1.5" and 2" panels can also be curved for use with radius roof situations.
All Maxima panels are mechanically seamed. Mechanical seamers and hand crimpers are available for rent through Developmental Industries (DI) at mcelroyseamers.com, a website created just for McElroy Metal customers. The rental fees for each type of equipment can be found on this site as well as additional information you may need to be aware of within the terms and conditions. DI is the only approved supplier for this type of equipment.
McElroy Metal provides factory eave notching on Maxima standing seam panels.
