C And Z Purlin Roll Forming Machine Steel Framing Automatic Production Line

The characteristics of Z purlin and C purlin (CZ purlin roll forming machine) are: a. Z purlin has better integrity than C purlin because the inertia distance in the direction of weak axis is larger than similar C purlin.

1. Because it has to be firmly lapped at the joint so that it becomes a continuous purlin after lapping, whereas C purlin can only be calculated as a simple purlin. Also, the selection of purlins is important.

2,When the general roof load is large and it is difficult to calculate C purlin or the calculated result needs to choose oversized C purlin, consider using Z purlin.

3,Area with large basic wind pressure, purlin calculation is often controlled by the wind suction force at this time, when it is difficult to calculate with C purlin can also choose Z purlin.(Changeable CZ profile roll forming machine)

4,It is recommended to use Z purlin when the roof panel is made of concealed buckle type board and the basic wind pressure of the project location is large. Because I have doubts about the reliability of the connection between the concealed buckle plate and the purlin, I am afraid that the concealed buckle plate will be sucked off under the action of larger wind, in case this happens, the stability of the purlin in the direction of the weak axis will be a problem. Generally the roof slope is small with C purlin, when the slope is large with Z purlin, generally the roof slope in 0.10 ~ 0.05 with C purlin calculation can meet!( Steel frame roll forming machine)

Manual decoiler--Guiding--Leveling--Roll fomring--Universal cut

This configuration of CZ forming machine equipment is also the most basic style, uncoiler manual, leveling machine mounted on the forming machine, forming machine using the pagoda chain structure, stopping the cut-off, cutting off the way is universal shear. Universal shear is a scissors, you can cut any size of the C-shaped can also cut any size of the Z-shaped, suitable for multi-size situation. Universal shear has scrap, customers can choose the front shear or staggered shear if they mind. The front shear requires the production of length greater than 3 meters, staggered shear requires a knife for each size, relatively higher cost, each has its advantages and disadvantages, we will give reasonable advice according to customer needs, to help customers choose the right equipment.
