Typically, galvanized iron sheets are available in various thicknesses measured in gauges. The most common standards range from 18 gauge (approximately 1.2 mm) to 26 gauge (approximately 0.5 mm). Thicker sheets, like 18 or 20 gauge, are commonly used in applications requiring structural strength, such as construction and industrial settings. In contrast, thinner sheets are often applied in manufacturing and household fixtures where weight and flexibility are crucial.
