Secondary Framing(Z and C Sections)
In every Pre-Engineered Metal Building (PEB), the secondary framing system plays a crucial role in enhancing the strength, stability, and durability of the overall structure. While the primary framing provides the main load-bearing support, the secondary framing of PEB structures ensures proper load distribution, connects cladding systems, and resists wind and seismic forces.
The secondary framing system typically includes:
- Purlins
- Girts
- Eave Struts
- Wind Bracing
- Flange Bracing
- Base Angles
- Clips
- Other Miscellaneous Structural Parts
All these components are manufactured from cold-formed steel sections with a minimum yield strength of 345 MPa (50,000 psi), meeting ASTM 572 (Grade 50), ASTM A653 (Grade 50), or equivalent specifications.
PURLINS & GIRTS
Purlins and girts are roll-formed Z-sections having various sizes as per design & stability (Example: 200 mm deep with 64 mm flanges and a 16 mm stiffening lip at 45˚). They are supported on rafters, columns, or building walls and can be lapped or nested at supports to create a continuous beam arrangement.
Purlins support roof sheeting.
Girts provide support to wall cladding.
together, they form a vital part of the structure framing system of PEB structures, ensuring strength and stability for long-term performance.

C SECTION
C-sections having various sizes as per design & stability (Example: 200 mm deep with 100 mm flanges perpendicular to the web, each having a 24 mm stiffening lip). These versatile members are widely used in the framing system for PEB to provide additional structural support.
EAVE STRUT
Eave struts are cold-formed members designed to match the slope of the roof. Typically, they are 200 mm deep with a 104 mm top flange and a 118 mm bottom flange, both with 24 mm stiffener lips. Positioned at the junction of the roof and wall, they transfer longitudinal wind loads from roof bracing to wall bracing, ensuring structural stability in pre-engineered buildings.
OPEN WEB JOISTS
Open web joists are long-span load-bearing trusses used to directly support roof decks and floors. They are fabricated with crimped angles welded to the top and bottom chords, making them an economical and efficient solution for PEB manufacturers.
CABLE BRACING
Cable bracing, made of extra-high-strength seven-strand cable, is essential for stabilizing buildings against wind, crane loads, and seismic forces. These cables are fixed using forged rod terminals, hillside washers, and nuts, ensuring maximum strength and reliability within the secondary framing of PEB structures.
