McElroy Metal manufactures a relatively low cost standing seam metal roofing panel called Meridian. It is 1 foot wide, has elongated fastening slots along one edge and the other edge snap locks together over the slotted edge. It is marketed by Metal Mart.
Has anyone used this ?
If so, how did the installation go, and has it held up ok ?
It's a common snaplock profile with many different names. It performs as expected for the price. I would not consider anything like this on any larger roofdeck but for small projects with minimal movement it's okay.
