A C-Purlin is a structural component typically used in roofing and wall framing. Its C-shape provides excellent load-bearing capabilities while being lightweight. The 75x45x15mm size is particularly popular among roofing fabricators for its perfect balance of strength and ease of handling. Galvanization, which involves coating the steel with a layer of zinc, enhances its resistance to corrosion, making it ideal for Singapore’s humid tropical climate.
