Roof Purlins C Type Z Type Roll Forming Machine Construction Material Machine

The angle of Z purlin and C purlin(Changeable CZ profile roll forming machine) is not the same, C type into 90 degrees, Z type is less than 90, roughly 60 to 75 degrees, so a certain slope of the roof using purlin should be combined with the knowledge of the force to consider the angle of purlin, slope using Z type can make full use of its bending performance.

Compared with Z-section, the mechanical properties of the strong and weak axes are different, and the connection with the rigid frame is mostly bolt hinged, so the calculation must be considered as simple support (Z-section can be rigidly connected by reliable lap, so it can be calculated as continuous beam). Therefore, the latter is more reasonable from the point of view of force state, calculation results and construction. Therefore, except for window and door openings and other special node treatment needs, Z-sections should be preferred. Wall purlins and roof purlins with a small shelf slope can choose C-shape; roof purlins with a large shelf slope should choose Z-shape, and it is best to make the combined force of the roof load pass through the section centre of Z-shape purlins.

Universal post-shear is CZ equipment commonly used scissors way, this scissors can manually adjust the width and height of the shear, for all sizes, but also shear C and Z-type, shear length is also arbitrary, so many customers will choose this shear, more economical. In the forming host can also be equipped with punching, punching the specific form to be designed according to the hole type drawings. Generally speaking simple bottom closing connection holes can be placed after forming shear before the installation and commissioning can save a lot of waste.
