Hauv Tebchaws Meskas, steel I-beams feem ntau tau teev tseg siv qhov tob thiab qhov hnyav ntawm lub nqaj. Piv txwv li, "W10x22" beam yog kwv yees li 10 hauv (254 mm) hauv qhov tob nrog qhov siab nominal ntawm I-nqaj los ntawm sab nrauv ntawm ib lub flange mus rau sab nrauv ntawm lub flange, thiab hnyav 22 lb / ft ( 33 kg / m). Dav flange seem kab teeb feem ntau txawv ntawm lawv qhov tob nominal. Nyob rau hauv rooj plaub ntawm W14 series, lawv tuaj yeem sib sib zog nqus li 22.84 hauv (580 mm).
Hauv tebchaws Canada, steel I-beams tam sim no feem ntau teev siv qhov tob thiab qhov hnyav ntawm cov nqaj hauv cov ntsiab lus metric. Piv txwv li, "W250x33" beam yog kwv yees li 250 millimeters (9.8 nyob rau hauv) qhov tob (qhov siab ntawm I-beam los ntawm sab nrauv ntawm ib lub flange mus rau sab nrauv ntawm lub flange) thiab hnyav li ntawm 33 kg / m (22). lb/ft; 67 lb/yd).[8]I-beams tseem muaj nyob rau hauv Teb Chaws Asmeskas qhov ntau thiab tsawg los ntawm ntau lub tuam txhab Canadian.
Hauv Mexico, steel I-beams yog hu ua IR thiab feem ntau teev tseg siv qhov tob thiab qhov hnyav ntawm cov nqaj hauv cov ntsiab lus metric. Piv txwv li, "IR250x33" nqaj yog kwv yees li 250 hli (9.8 nyob rau hauv) qhov tob (qhov siab ntawm I-nqaj los ntawm lub ntsej muag sab nraud ntawm ib lub flange mus rau sab nrauv ntawm lub flange) thiab hnyav li ntawm 33 kg / m (22). lb/ft).
Hauv Is Nrias teb, I-beams raug xaiv los ua ISMB, ISJB, ISLB, ISWB. ISMB: Indian Standard Medium Weight Beam, ISJB: Indian Standard Junior Beams, ISLB: Indian Standard Light Weight Beams, thiab ISWB: Indian Standard Wide Flange Beams. Beams raug xaiv raws li ib qho kev siv abbreviated raws li qhov tob ntawm seem, xws li piv txwvSIB 450, qhov twg 450 yog qhov tob ntawm seem hauv millimeters (mm). Qhov ntev ntawm cov kab teeb no raug cais raws li IS: 808 (raws li BIS).
Nyob rau hauv lub tebchaws United Kingdom, cov steel seem no feem ntau teev nrog ib tug code uas muaj xws li loj dimension, feem ntau yog qhov tob, -x-qhov me me-x-qhov loj ib meter-kawg nrog cov seem hom, tag nrho cov kev ntsuas yog metric. Yog li ntawd, 152x152x23UC yuav yog ib kab ke (UC=universal kem) ntawm kwv yees li 152 mm (6.0 in) qhov tob, 152 mm dav thiab hnyav 23 kg / m (46 lb / yd) ntawm qhov ntev.
Hauv tebchaws Australia, cov seem hlau no feem ntau hu ua Universal Beams (UB) lossis Columns (UC). Lub npe rau txhua tus yog muab raws li qhov kwv yees qhov siab ntawm lub nqaj, hom (nqaj lossis kem) thiab tom qab ntawd lub ntsuas ntsuas ntsuas (piv txwv li, ib qho 460UB67.1 yog kwv yees li 460 hli (18.1 nyob rau hauv) tob universal beam uas hnyav 67.1 kg. / m (135 lb/yd)).
