C purlins are horizontal beams commonly used in the construction industry to provide structural support to roofs and walls of buildings. These cold-formed steel sections have a distinctive shape resembling the letter "C," featuring a flat, perpendicular section known as the web and two flanges that extend outward at right angles. They are lightweight yet strong, making them ideal for spanning long distances without adding excessive weight to the overall structure. C purlins are versatile and can be easily installed, offering stability and support to roofing materials such as metal sheets or panels. Their design allows for efficient distribution of weight, enabling them to withstand heavy loads while maintaining structural integrity. This adaptability, combined with their durability and cost-effectiveness, makes C purlins a popular choice in various construction projects, including commercial buildings, warehouses, and agricultural structures.
