During the construction of metal buildings or steel structural buildings, we always use steel purlin! Among the popular c and z steel purlins, we may have questions about which one to use. Therefore, regarding this, we will give some brief introduction in the article.
Firstly, a purlin is a horizontal beam or bar used for structural suppport in buildings, most commonly in a roof. Several kinds of purlins exist. People like to divide them into categories based on their material and shape. The purlin most commonly used in roofing is the steel purlin. Nowadays, we produce “C” and “Z” (Cee and Zed) shaped channels via c purlin roll forming machine and z purlin roll forming machine from high-strength zinc-alloy coated steel with minimum yield stress 60% higher than the respective profiles formed through hot forming. This means that we can use sections of minimum thickness and weight, resulting in reduction of the time and the cost of the construction.
And then, people tend to use C and Z steel purlins on their steel framed buildings, in order to provide an efficient, lightweight and cost efficient roofing, cladding and walling support system (Purling and girt system).
