B&B Sheet Metal’s Series A1101 defines clean lines with architectural interchangeability to provide continuous seam transitions from roof to fascia, wall panel or soffit. The A1101 narrow standing seam profile requires no mechanical seaming or separate seam cap. The integrated nail strip and fasteners provides a clipless design for fast and easy installation ideal for light duty commercial metal roofs, residential and mansard/canopy applications on a solid deck. Maximum panel length is 45 feet and minimum 24 inches.
