Technical writing is really difficult but if we understand it clearly then it becomes the most interesting topic. Last Sunday I was just sitting like a lazy bird then suddenly something cropped up my mind. The term was Z Purlin. For a minute I was confused what does it mean but when I found out its real meaning, I became more fascinated to know what it really is and how it functions.
It is a light-gauge member with a Z-like cross section. The pre-punched purlins are fast to install and appropriate for both insulated and uninsulated roofs and walls. The depth and height of the purlin carefully chosen depend on span distance and loads. To improve the design, the PurCalc software is used. It is used in applications such as:
Industrial construction
Hall and warehouse construction
Extension construction and renovation
In structural design, structural engineering or constructing edifice, a purlin (or factually purline, purloyne, purling, perling) is any horizontal, longitudinal, structural member in a rooftop apart from a type of edging with what is called a crown plate. In outmoded Timber framing there are three elementary types of purlin: purlin plate, principal purlin and common purlin.
All of these have their own specialty and are used according to the requirement of the work.
