Cold Formed “Purlins” for Structural Integrity

Cold Formed “Purlins” are an essential component in modern construction, designed to provide superior support and strength to various building structures. These purlins are commonly utilized in two primary building systems: overlapped and sleeved connections, each offering unique benefits depending on the application.

In the overlapped system, Cold Formed “Purlins” are primarily used in large buildings with long spans. This system is preferred for its ability to add extra strength and stiffness, particularly over the rafter area, making it ideal for industrial and commercial buildings where structural integrity is paramount.

On the other hand, the sleeved connection system employs Z sections, which are crucial for buildings that are two or more bays long. This system utilizes continuous purlin sleeves, allowing for seamless and uninterrupted support across multiple sections of the structure. Purlins in this application ensure that the building remains robust and reliable, even under heavy loads or adverse weather conditions.

Cold Formed “Purlins” are versatile and can be extended in various ways to meet specific design requirements. One option is an end extension, where the purlins or side rails are elongated to achieve the desired overhang. Typically, these purlins are manufactured with standard end holes, to which overhang fixing holes are added according to individual project needs.

Another method involves a continuous extension, particularly useful when the required overhang exceeds half of the standard sleeve length. In this scenario, Cold Formed “Purlins” are extended in a way that ensures the overhang is supported without compromising the structural integrity of the building.

Finally, in cases where a more precise fit is necessary, a continuous extension can be customized by cutting the standard sleeve to the exact length required. This approach offers flexibility and precision, making Purlins a highly adaptable solution for various construction challenges.

By choosing Cold Formed “Purlins” for your project, you are investing in a product that offers both reliability and adaptability, ensuring that your building can withstand the demands of its environment while meeting your specific design requirements.
