Australia standard High Strength Galvanized Purlins/Girts with its Bridging Accessories
Australian/British/New Zealand standard galvanized steel purlin beam adopts hot rolled sheet cold bending forming, thin wall, lightweight, good section performance, high strength. The material is 500 or 550MPA high strength. Common steel purlins are Z-shaped steel purlins and C-shaped steel purlins. Steel purlins are secondary load-bearing members of the roof structure system, which transfer the roof load to the steel frame.
We have high-strength AS/NZS, BS EU standard purlins, and girders. Welcome customers in need to inquire.
In architecture, structural engineering, or construction, a purlin (or historically purline, purloined, purling, peeling) is any longitudinal, horizontal structural member of a roof, except for a type of frame called a crown plate. In the traditional wooden frame, there are three basic types of purlins: plate purlins, main purlins, and ordinary purlins.
In steel construction, the term purlin usually refers to a roof frame member that spans parallel to the eaves of the building and supports the roof deck or plate. Purlins are supported by rafters or walls. Purlins are most commonly used in metal building systems, where the Z-shaped form of use allows for curved continuity between spans.
In practice in the iron and steel industry, structural shapes are given representative names for easy shorthand description in drawings and documents: the channel section, with or without flange stiffeners, is often cited as the C-shape; The channel section without flanged stiffeners is also known as U-shaped; A point-symmetric cross-section shaped like the letter Z is called a Z-shape. The segment name can be regional or even manufacturer-specific. In steel construction, secondary elements such as purlins (roofs) and girders (walls) are usually cold-formed C, Z, or U, and (or mill-rolled)C.
Cold-formed members can be effectively applied based on the weight of the secondary members relative to the rolling parts of the mill. In addition, the Z-section can be nested for transport bundling and, on the building, lapped on the supports to form a structurally efficient continuous beam spanning multiple supports.
