We also offer the "R" panel and 8 different profiles of standing seam. All of our panels come with a 25 to 30 year color warranty. Our bolt together buildings are easier to erect. We offer numerous colors for the roof, walls and trim. Each color is backed by a 25-year warranty against fading, chipping, pealing and cracking. We offer standing seam panels in a wide variety of colors. These panels come in 26 and 24 gauge. The panels come in various widths from 12" to 24". These panels can be smooth or striated to protect against oil canning. Our nail fin panel can be attached to the roof with screws. Then the next nail fin panel is snapped down over the screws hiding them from the weather. Our snap seam panels are attached to the roof with clips.
