C-Z Purlin Machine

C-Z Purlin Industry
C-ZPurlin is an integral part of light steel structure. C/Z purlin is made of hot rolled steel, hot rolled galvanized steel, hot dip galvanized steel and high strength steel. After the process of continues roll-forming, C/Z purlin gained the following features.
Features of Cee and Zee profile:
● Dead weight is very light. The section performance in unit weight is excellent. For same area, steel quantity can be reduced, lowering the material costs.
●It is of high strength. It can be closely connected, increasing the bearing capacity of the structure.
● It is easy to install. It can be tailor made on large quantity. Digital scale, machine-made drilling and removing rust are finished in workshop. It can be installed once it is transported to the worksite.
● Smooth surface, precise size, excellent rust-resistance property and long-term durability.
With the advantage of Cee & Zee purlin, they are widely used as the supporter of roof and wall in large-scale and mid-scale construction, such as factory, warehouse, garage, exhibition center, cinema, theatre, garden in steel structure industry and so on.
