A galvanized lip channel is a type of metal channel that is used extensively in various construction applications, including roofing. The ‘lip’ refers to the protruding edge that enhances its structural stability. The 1.9mm thickness provides a perfect balance between strength and weight, making it ideal for roofing applications. The galvanization process involves coating the steel with a layer of zinc, which protects it from corrosion and extends its lifespan.
