The wide range of thicknesses (gauges) available for allows for precise engineering to meet specific project load and durability requirements, although aluminum is typically specified by thickness in millimeters (e.g., 0.7mm, 0.9mm, or 1.2mm) rather than the gauge used for steel products. Thicker materials offer superior resistance to impact damage, oil canning (waviness), and wind u... https://kkroofspecialist.com.sg/aluminum-roofing-material-singapore/
