Roofing Sheet

Secondary GP sheet thickness typically ranges from 0.30 mm to 3 mm, with common thicknesses including 1 mm to 2 mm and 1 mm to 3 mm, depending on the supplier and product specifications. The term "Secondary" indicates that it may have minor imperfections, while "GP" refers to Galvanized Plain or Galvanized Plate, meaning it's a hot-rolled, rectangular, galvanized steel sheet.
