What are the different thicknesses and grades of aluminum profiles used for roofing?

Aluminum profiles for roofing come in different thicknesses and grades, which determine their strength and suitability for various applications. Common thicknesses range from 0.5mm to 1.5mm, with 0.5mm and 0.6mm being the most common for residential roofing. For commercial and industrial applications, thicknesses of 0.8mm to 1.5mm are often used due to their increased load-bearing capacity. Grades of aluminum profiles are typically classified based on their alloy composition, with 1100, 3003, 5005, and 6061 being the most common. Each grade has different properties, such as corrosion resistance, formability, and strength, which make them suitable for specific roofing applications. For instance, 3003-grade aluminum is widely used for roofing due to its good formability and moderate strength. The choice of thickness and grade depends on the specific requirements of the roofing project, such as the expected load, environmental conditions, and aesthetic preferences.
