Thin-wall curled Z-type purlin (galvanized)

The difference between Z-shaped steel and C-shaped steel:

1. Z-shaped steel is suitable for roof slope i> 1/3, C-shaped steel is suitable for roof slope i <1/3

2. Z-shaped steels can be stacked and stacked, and occupy less space.

3. When the Z-shaped steel is used as a continuous purlin, the bearing performance is good. Under the same conditions, the steel consumption is saved compared to the C-shaped steel. When the roof panel adopts the concealed button and the basic wind pressure in the project area is large, it is recommended to use the Z-shaped steel for the roof purlin .
