C-Purlins

C-Purlins are cold-formed steel components shaped like the letter “C.” They are commonly used as secondary framing in smaller-scale or lighter-load buildings where strength and economy are both important.

Unlike Z-Purlins, which overlap for continuous spans, C-Purlins are typically used as individual members for shorter spans or where overlaps aren’t required.

Indaco Metals fabricates C-Purlins to precise specifications, ensuring compatibility with your building design. They provide reliable support for roof panels, wall panels, and other structural elements, making them an excellent choice for garages, workshops, agricultural sheds, and smaller commercial facilities.
