C Type Machine for Rolling

Purlin roll forming machine can be divided into cement purlin roll forming machine and steel roll forming machine.

The cable tray roll forming machine can be divided in to C type and Z type metal roll forming machine. And there are some differences between the C type and Z type. First, the weak axis of inertia from of Z purlin is larger than that of C purlin, so its integrity is better than C purlin.?Second, because the joint should firmly lap, lap after such as continuous purlin, and the C purlin can only be calculated on the simply supported purlin. At the same time, the selection of purlin is also very important:

If the general roof load is bigger, a, C purlin dyscalculia or calculated results need large C purlin, you can consider using Z purlin.

If there have larger areas of basic wind pressure, purlin calculation at this point is often controlled by the wind suction, if using C purlin calculation has difficulties at this time, you also can choose Z purlin.
