Secondary Members/Cold Formed Members
Secondary structural framing mentions to purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and other various structural parts. Purlins, girts and eave struts are cold formed steel members which have a minimum yield strength of 345 MPa (50,000 psi) and will conform to the physical specifications of ASTM 572 (Grade 50) or ASTM A653 (Grade 50) or equivalent.
PURLINS & GIRTS
Purlins and girts are roll formed Z sections, 200 mm deep with 64 mm flanges shall have a 16 mm stiffening lip formed at 45˚ to the flange. They are supported on columns, rafters or building walls. They can be lapped and nested at the supports which creates a continuous beam configuration. They are placed on the roof and perimeter of the building. Hence they serve as a support to the roof sheeting and wall cladding.
C SECTION
C-Sections are 200 mm deep with a 100 mm flange. The flanges are perpendicular to the web and have a 24 mm stiffening lip.
EAVE STRUT
Eave struts are 200 mm deep with a 104 mm wide top flange, a 118 mm wide bottom flange, both are formed parallel to the roof slope. Each flange has a 24 mm stiffener lip. These are located along the sidewall; at the intersection of the planes of the roof and wall. It is constructed from cold formed C-Section and is rolled to suit the roof slope. This member transmits longitudinal wind force on the end walls from roof brace rods to wall brace rods.
OPEN WEB JOISTS
These are long span load carrying trusses suitable for direct support of floors and roof decks in the buildings. The system consists of crimped angles welded to the top and bottom chords.
CURVED EAVES
Curve Eaves can transform the look of any building. Curved canopies and walkways provide an inviting entryway into commercial establishments. Curved eaves eliminate seam lines and provide a smooth line for the eye to follow. Our crimping-curving process increases the rigidity of the curved panels making this choice of panels not only visually appealing but also practically durable.
