Standing SeamCurved Metal Roofing

Standing Seam Curved Metal Roofing

Curves are in! Whether simply used as a design accent or for an entire roof, radius roofing is gaining in popularity. McElroy Metal offers five distinct standing seam systems that can be curved right on the job site which both lowers transportation cost and helps ensure a proper fit. Our curved standing seam system options include Maxima 1.5, Maxima ADV, 138T, 238T, and Medallion I.

Maxima 1.5, Maxima ADV, 138T, and 238T standing seam panels are curved on the job site by McElroy Metal roll forming technicians. Conversely, Medallion I curving is performed on the job site by roofing contractors using rented curving equipment available through Developmental Industries at mcelroyseamers.com, DI is the only approved supplier for this type of equipment.

Medallion I

McElroy’s Medallion I standing seam system is comprised of a panel and separate batten cap. There are two main differences between this system and our other curved roofing systems:  

1. The roofing contractor (as opposed to McElroy) completes the curving process onsite with equipment they are responsible for renting  from Developmental Industries.

2. Medallion I is our only curved product that offers a snap on batten instead of a mechanically seamed batten.
