Q235 Q355 Hlau H Beam

Q235 steel yog ib qho yooj yim carbon structural steel uas yog dav siv nyob rau hauv Tuam Tshoj, Q235 khoom nyob rau hauv Suav standard GB / T 700 muab faib ua 4 qib zoo: Q235A, Q235B, Q235C thiab Q235D; Qhov ceev ntawm cov hlau no yog 7.85 g / cm3, tensile zog yog 370-500 MPa; yield zog yog 235 MPa. Txij li nws yog cov hlau me me, nws yog siv ncaj qha yam tsis muaj kev kho cua sov.

Q355 steel yog Suav tsis tshua muaj alloy siab zog steel qauv, uas hloov Q345, cov khoom ceev yog 7.85 g / cm3. Raws li GB/T 1591 -2018, Q355 muaj 3 theem zoo: Q355B, Q355C thiab Q355D. "Q" yog thawj tsab ntawv ntawm Suav Pinyin: "qu fu dian", uas txhais tau tias Yield Strength, "355" yog qhov tsawg kawg nkaus tus nqi ntawm yield zog 355 MPa rau steel thickness tsawg dua los yog sib npaug rau 16 hli, thiab tensile zog yog {{ 14}}Mpa.

H-Beam thiab I-Beam: Cov ntawv thov

H-Beams thiab I-beams zoo sib xws, tab sis lawv muaj kev sib txawv. Yog tias koj xav siv ob qho ntawm lawv rau koj qhov project tom ntej, ntawm no yog qhov koj yuav tsum paub:

Txoj hauv kev zoo tshaj plaws los txiav txim siab seb lub nqaj twg yog qhov zoo tshaj plaws rau koj qhov project yog kev sab laj tus kws tshaj lij. H-beams zoo dua los txhawb nqa lub nra ntawm hauv pem teb thiab lub ru tsev nyob ntev dua, thaum i-beams zoo dua los txhawb qhov hnyav ntawm phab ntsa lossis kem.

Yog tias koj txiav txim siab ntawm H-beam lossis I-beam, nco ntsoov tias cov kab teeb no muaj qhov sib txawv yam tsawg kawg nkaus; qhov no txhais tau hais tias yog tias koj qhov chaw muaj qhov loj (piv txwv li, nws ntev), ces qhov I-nqaj yuav tsis zoo rau nws vim nws xav tau cov khoom siv ntau dua li lwm cov qauv tsim.
