Flange Dav (deb ntawm cov flange cov npoo) sib txawv los ntawm qhov siab rau australian Pfc channel steel, xws li 45 hli (PFC 400):
Cov PFC me me: PFC 75 (45 hli Flange Dav), PFC 100 (50 hli Flange Dav)
Nruab Nrab PFC Qhov ntau thiab tsawg: PFC 200 (75 hli Flange Dav), PFC 250 (85 hli Flange Dav)
Large PFC sizes: PFC 350 (125 mm flange width), PFC 400 (150 mm flange width)Flange width directly impacts load distribution and lateral stability-wider flanges reduce the risk of lateral-torsional buckling in long-span applications (e.g., warehouse roofs). AS/NZS 3679.1 specifies flange width tolerances: ±0.8 mm for widths ≤60 mm, ±1.0 mm for 61–100 mm, and ±1.5 mm for >100 hli. Cov thev naus laus zis kom ntseeg tau cov channel fits kom raug nrog Australian- Txheem bolts (piv txwv li 152) thiab cov nkhaus, tiv thaiv kev thauj khoom.
