Z-shaped purlins and C-shaped purlins are two common steel structural materials, with notable differences in shape, strength, and application.

Shape:
Z-shaped purlins have a sawtooth-like cross-section with two flanges and a web, while C-shaped purlins have a C-shaped cross-section with one flange and a web. Due to its unique shape, Z-shaped purlins can interlock with each other during connection and stacking, enhancing structural stability and load-bearing capacity. On the other hand, the design of C-shaped purlins makes them particularly convenient for simpler structural applications.

Strength:
Z-shaped purlins offer better bending and torsional resistance, making them more suitable for structures with long spans or heavy loads. For instance, Z-shaped purlins are commonly used in industrial plants and large warehouses to support roofs and other facilities. In contrast, C-shaped purlins are more appropriate for shorter spans and lighter loads, often used in smaller buildings or lightweight roof trusses.

Application:
Z-shaped and C-shaped purlins have distinct application ranges. Z-shaped purlins, with their higher strength and stability, are typically employed in more complex and demanding engineering projects. C-shaped purlins, on the other hand, are widely used in simpler constructions such as barns, basic warehouses, and similar structures.

In summary, while both Z-shaped and C-shaped purlins are essential components of steel structures, their differences in shape, strength, and applicability make them suitable for different practical uses. Choosing the right type of purlin should depend on the specific requirements of the project.
