Overview
Components:
-
Purlins & Girts: Horizontal members supporting roof and wall panels.
- Eave Struts, Bracings & Sag Rods: Provide lateral support and transfer loads to primary frames.
Key Facts:
-
Typically account for 15–20% of total steel used in a PEB structure.
- Cold-formed steel sections (C/Z shapes) dominate due to light weight and strength.
Trends & Opportunities:
-
Mass production and cold roll-forming innovations driving cost efficiency.
- High demand in multi-span warehouses and large logistics parks.
- Bracing systems increasingly optimized using software-based load simulations.
Opportunity:
- High ROI as secondary systems reduce material cost while improving structural performance.
- Growing preference for galvanized sections due to durability and anti-corrosion needs.
