C&Z galvanized section roof purlin making machine is a kind of cold roll forming machine that is used to produce C-shaped and Z-shaped steels. The finished pruducts, C&Z purlin, are widely applied in supporting residential and commercial buildings as well as solar panel mounting structure and cable tray. Our C&Z galvanized section roof purlin making machine is easy to operate with the touch screen controller PLC. This kind of machine can change the profile and specifications automatically without replacing rollers if different sizes of products are needed.
What is Purlins?
Purlins carry the roof deck or sheathing loads and are supported by large rafters and/or building walls, steel beams, etc. In comparison to closely spaced rafters, the use of purlins is common in pre-engineered metal construction systems and both the ancient post-and-beam and newer pole construction methodologies for frame construction.
Purlins pass roof loads to the major structural elements supporting the roof; the form and arrangement of purlins is a design factor that depends on the instance of roof loads as well as the limiting sheeting lengths to use. In the final analysis, local building codes should always be understood and implemented in the design of a concrete roof structure.
What Purpose Do Purlins Serve in a Steel Building?
To understand this we really need to get down to the basics of roof purlins in metal construction. Purlins are an integral part of a pre-engineered structural steel package. Such structural supports extend through the rafter beams perpendicularly. Often known as “sheeting sheets,” purlins provide the roofing portion of a steel building’s secondary framing. Three structural functions are provided by metal roofing purlins.
Firstly, the roof is protected by the purlins. Second, purlins tie the rafters together, stabilizing and reinforcing the rigid framing of the frame. And the third, between the spans of the individual framing bays, purlins provide additional support. As an added benefit, purlins increase the resistance of the system to excessive rainfall.
