The Lámina KR-18 (KR18 sheet) is a very popular standing seam metal roofing profile used in Mexico and Latin America. It is roll-formed on site with a portable machine, which allows for long continuous panels without transverse overlaps.
Profile type: Standing seam (no exposed fasteners).
Locking system: Uses a clip system (fixed or floating) that allows thermal expansion and contraction.
Seam height: 2.5" (approx. 65 mm).
Panel width: Effective cover width around 45 cm (varies by machine).
Material: Galvanized steel, Galvalume (AZ), pre-painted steel, or aluminum.
Thickness (Calibre): Commonly 22–24 gauge (0.7–0.5 mm).
