Features and Usage

The rollers of the Z purlin forming machine are made of forged quality structural steel after intense treatment. Coated with the hard chromium on the surface, the roller performs with expanded operation life.
Under the control of computer, the machine accomplishes the length setting, punching and counting smoothly.
The flattening rollers at the front end of the Z purlin forming machine are adopted to make the strip steel flat and smooth enough to meet the standards, making an increase of economic benefit.
The Z purlin fabricated by our machine performs excellently on resisting bending. It is also easy for installation.
The Z shaped purlin is commonly used in the middle and large scaled buildings like the factory, warehouse, garage, gymnasium, exhibition center, cinema, theatre, garden and so on. It is perceived as the applicable building materials to support the roof or forming the wall.
