Product Overview
The Steel Purlin is a horizontal structural member used to support roof and wall cladding systems in steel structure buildings. Installed between the main steel frames, steel purlins transfer loads from the roof or wall panels to the primary structure, ensuring overall stability and load distribution.
Steel purlins are widely applied in:
Industrial workshops and factories
Warehouses and logistics buildings
Commercial steel buildings
Agricultural buildings
Steel structure sheds and hangars
Common types include:
C-section steel purlin
Z-section steel purlin
