Steel purlin is a secondary load-bearing member widely used on steel roofs. It connects roof panels to the main space frame structure and transfers roof loads to the space frame system.
We mainly supply two common types: C purlin and Z purlin.
Our factory rolls purlins from high-strength cold-formed steel strips. We provide hot-dip galvanized surface treatment to resist rust in humid, dusty environments.
Precise dimensions guarantee easy installation on bolt ball space frame roof projects.
Core Advantages
- Light weight but high structural strength, reduces overall roof load
- Hot-dip galvanized finish for long anti-corrosion life
- Quick on-site installation, saves labor and construction time
