Galvanized purlins and girts
The Australia/UK/New Zealand standard galvanized steel purlin girts are cold-formed by hot-rolled sheet, thin wall, light weight, excellent cross-section performance and high strength. The material is Grade 500 or 550MPA high strength. Common steel purlins include Z-shaped steel purlins and C-shaped steel purlins. Steel purlins are a secondary load-bearing component in the roof structure system, which transfers roof loads to the steel frame.
We have high strength AS/NZS, BS EU etc standard purlins and girts under sale chart. welcome clients in need to enquiry it.
In architecture, structural engineering or building, a purlin (or historically purline, purloyne, purling, perling) is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin and common purlin.
In steel construction, the term purlin typically refers to roof framing members that span parallel to the building eave, and support the roof decking or sheeting. The purlins are in turn supported by rafters or walls. Purlins are most commonly used in Metal Building Systems, where Z-shapes are utilized in a manner that allows flexural continuity between spans.
It is the practice in the steel industry that structural shapes are assigned representative designations for convenient shorthand description on drawings and documentation: Channel sections, with or without flange stiffeners, are usually referenced as C shapes; Channel sections without flange stiffeners are also referenced as U shapes; Point symmetric sections that are shaped similar to the letter Z are referenced as Z shapes. Section designations can be regional and even specific to a manufacturer. In steel building construction, secondary members such as purlins (roof) and girts (wall) are frequently cold-formed steel C, Z or U sections, (or mill rolled) C sections.
Cold formed members can be efficient on a weight basis relative to mill rolled sections for secondary member applications. Additionally, Z sections can be nested for transportation bundling and, on the building, lapped at the supports to develop a structurally efficient continuous beam across multiple supports.

Purlins are quite popular these days and are available in different shapes and sizes in the market. Commonly it looks similar to the English alphabets and some of the most commonly used purlins consist of Z and C Purlins. The major reasons of its popularity is, with the use of the purlin roof coveringhouse top or roof can be given different shapes as per the desire of the owner or customer. So it does not matter if an individual is willing to give its roof a flat or cone shaped look all of it will fit perfectly well with purlins.
This roof purlin is made of good quality steel such that it can bear the load of a building and remain firm and steady. Hence individuals can pick up any of them according to their choice and preference.It can also be used in wooden construction and it is also called as arcade plate. These plates can also be called as beams which provide support to rafters. These rafters thus form the basis of a wider building.
Installation of purlins is quite an easy task. The purlins made of steel can be easily cut with nibbler however it be any material all of them requires traditional form of fixing such that it can remain steady for many years to come. But the best part of using a purlin is it is light weight and its width, length and height all of it can be customized according to the wish of customers. Purlin roof thus makes the roof a lot firm and solid as per the desire of users.
