Purpose & Use

1.25″ Corrugated is flexible enough to handle moderate curvatures – its lower profile ribs are decorative but still strong.

Common uses for 1.25″ Corrugated include interior walls, ceilings, and siding. Because of the low ribs, 1.25″ Corrugated is primarily decorative if used on roofs. Galvalume, galvanized, and painted finishes completely change the look and style of a project.

Excellent Product and Great Customer Service from Nathan and Glory. Who knew Galvalume would look so excellent as a ceiling product? We did! And we couldn’t have done it without the help of Best Buy Metals. Thank you.
