How to Order Zee Purlins
1. Purlin Profile
The shape of Zee Purlins resembles the letter "Z," with two flanges (or lips) connected by a vertical section. The flanges are the horizontal parts that provide strength and rigidity, while the vertical section acts as a connecting member.
Zee Purlins are available in different sizes and thicknesses to accommodate varying loads and span lengths. The selection of the appropriate purlin profile depends on factors such as roof or wall design, wind and snow loads, and the overall structural requirements of the building.
