Purlins carry the roof deck or sheathing loads and are supported by large rafters and 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.

As the widely usages of C purlin in daily life, we design the fully automatic C purlin rolling machine, as to the automatic stacker it is optional;

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).

How to adjust the machine when thickness changes? For example from 1.5 to 3.0mm.

If the thickness of the replacement material does not exceed 0.5mm, such as changing from a material with a thickness of 1.5mm to a material with a thickness of 1.8mm, there is no need to adjust the machine. If the thickness change exceeds 0.5mm, it is necessary to adjust the gap between the upper and lower rows of forming rollers of the machine. If the thickness increases, the gap needs to be increased, and if the thickness decreases, the gap needs to be reduced.For example from 1.5 to 3.0mm, you need to increase the gap between upper roller and lower roller of all the stations. Use a ruler to measure the gaps and make it increase by 1.5mm.

Steel frame purlin machine is a mechanical equipment used for producing purlins in steel structure buildings. Purlin is a secondary load-bearing component in the roof structure system, mainly used to support the main rafters and roof materials, and to transfer roof loads to the steel frame.

Shaped and Z-shaped steel are the most commonly used types of purlins because they have a high strength to weight ratio, which can effectively carry and distribute the load on the roof.
