Hauv Tebchaws Meskas, feem ntau hais txog I-beam yog qhov dav-flange (W) zoo li. Cov kab teeb no muaj flanges uas lawv sab hauv yog sib npaug rau feem ntau ntawm lawv cheeb tsam. Lwm yam I-beams muaj xws li American Standard (tsim S) cov duab, nyob rau hauv uas puab flange nto tsis sib npaug, thiab H-piles (tsim HP), uas feem ntau yog siv los ua pawg hauv paus. Cov duab dav dav muaj nyob hauv qib ASTM A992,[5]uas feem ntau tau hloov cov laus ASTM qib A572 thiab A36. Ntau yam ntawm yield zog:
A36:36, 000 psi (250 MPa)
A572:42, 000–60, 000 psi (290–410 MPa), nrog 50, 000 psi (340 MPa) feem ntau
A588:Zoo ib yam li A572
A992:50, 000–65, 000 psi (340–450 MPa)
Zoo li feem ntau cov khoom siv hlau, I-beams feem ntau muaj qee cov ntsiab lus siv dua.

Lub koom haum American of Steel Construction (AISC) luam tawm covKev Siv Hluav Taws Xob Hlaurau kev tsim cov qauv ntawm ntau yam duab. Nws sau cov txheej txheem sib xws, Tso Cai Tsim Lub Zog (ASD) thiab Load and Resistance Factor Design (LRFD), (pib 13th ed.) los tsim cov qauv zoo li no.
