Material Standards & Grade Designations:
Cov qhab-nees teev sawv cev rau cov pa roj carbon ntau thiab cov hlau me me thoob ntiaj teb, categorized los ntawm lawv cov txheej txheem tswj hwm:

General Structural Steel (ASTM & JIS):

ASTM A36 Txuj:Ib qho tseem ceeb hauv Teb Chaws Asmeskas tus qauv rau carbon steel, nrog rau qhov tsawg kawg nkaus lub zog ntawm 36 ksi (≈250 MPa). Prizeed rau nws zoo heev weldability thiab formability nyob rau hauv kev tsim kho.

SS440 (JIS G 3101):Ib qib Japanese tus qauv nrog lub zog tensile yam tsawg kawg nkaus ntawm 440 MPa. Nws yog feem ntau siv rau hauv cov qauv dav dav thiab tshuab, muab qhov sib npaug ntawm lub zog thiab kev tsim khoom.

European Tsis yog{0}}Alloy Structural Steels (EN 10025-2):Cov qib no yog txhais los ntawm qhov tsawg kawg nkaus tawm lub zog thiab cuam tshuam toughness.

S235JR:Yield zog Ntau dua los yog sib npaug rau 235 MPa. Qhov kev xaiv "JR" qhia qhov tsawg kawg nkaus lub zog ntawm 27J ntawm +20 degree, haum rau kev siv dav dav.

S355JR / S355J2:Siab dua - qib zog nrog cov txiaj ntsig Ntau dua lossis sib npaug li 355 MPa. "JR" muaj 27J ntawm +20 degree, thaum"J2"npe 27j-20 degree, muab kev txhim kho kev sib tw toughness rau cov ntawv thov raug txo qis kev pabcuam kub.

Suav Carbon Structural Steels (GB / T):

Q235B:Yield zog Ntau dua los yog sib npaug rau 235 MPa. Piv rau S235JR thiab A36 hauv kev ua haujlwm zoo, dav siv hauv kev tsim kho.

Q355B:Yield zog Ntau tshaj los yog sib npaug rau 355 MPa. Tus GB sib piv rau S355JR, muab lub zog ntau dua rau kev thov cov qauv siv ntau dua.

Manufacturing Txheej Txheem & Profile Geometry:

Kub Rolling:Tag nrho cov seem yog tsim los ntawm cov txheej txheem kub - dov, qhov twg cov hlau yog rhuab saum toj no nws cov recrystallization kub thiab dhau los ntawm ib tug series ntawm yob. Txoj kev no tsim cov qauv hlau tsis sib xws, txhim kho cov khoom siv tawv, thiab tso cai rau kev tsim ntau yam ntawm cov ntoo khaub lig nyuaj-sectional shapes nrog rau qhov zoo sib xws.

Hla -Sectional Profiles & Applications:Txhua qhov profile yog tsim los ua kom zoo tshaj qhov kev faib khoom rau kev thauj khoom tshwj xeeb -cov kabmob ua haujlwm.

H-Beams (Wide Flange Beams):Characterized los ntawm wider, thicker flanges parallel rau ib leeg. Qhov no geometry muab superior load-cov kabmob muaj peev xwm nrog lub zog zoo-rau- hnyav piv, ua rau lawv zoo tagnrho raukem, hnyav- lub luag haujlwm beams, thiab lub hauv paus ntsiab lusntawm cov tsev thiab cov choj.

I-Beams (Standard Beams):Feem ntau muaj tapered flanges nrog ib tug nqaim profile tshaj H-beams. Ua tau zoo rau kev nqa shear loads hauv lub vev xaib thiab khoov lub sijhawm dhau qhov nruab nrab, feem ntau siv los uakab rov tav txhawb nqa kab.

Tshooj Tshooj (C/U Tshooj):Featuring "C" lossis "U" duab nrog ib sab qhib. Lawv muab zoo dabtsi yog khoov zog nyob rau hauv ib qho kev taw qhia thiab feem ntau siv raws lipurlins, framing cov tswv cuab, ntug reinforcements, thiab nyob rau hauv lub teeb rau nruab nrab kev txhawb nqa.

Hauv cov ntsiab lus, cov khoom lag luam no tau txhais los ntawm nws ob lub hauv paus ntawmcov ntaub ntawv versatilitythiabprofile tshwj xeeb. Qhov muaj cov qhab nia thoob ntiaj teb lees paub ua kom muaj kev ua raws cai thiab kev ua tau zoo thoob plaws cov qauv engineering sib txawv. Raws li qhov tshwm sim, qhov ntau ntawm H, I, thiab C / U profiles tso cai rau kev xaiv meej ntawm cov qauv siv tau zoo tshaj plaws thiab tus nqi -ib ntu zoo rau txhua daim ntawv thov, los ntawm lub tsev thav duab thiab kev lag luam platform los txhawb cov qauv thiab kev tsim kho.
