SRUBIJA JEZIK (LATINICA)Common Suav structural steels
Suav structural steels, standardized raws li lub teb chaws codeGB/T 1591thiab siv nyob rau hauv tsim perGB 50017-2017, tau ua tiav daim ntawv thov dav dav thiab kev lees paub. Los ntawm kev ntsuas kev ua tau zoo, lawv tau tsim kom muaj qhov sib npaug nrog cov qauv thoob ntiaj teb loj.
Tus tsim lub zog Performance index ntawm steel yuav tsum tau txiav txim raws li cov qib steel, thickness los yog txoj kab uas hla raws li ib tug nram qab no cov lus.
(Plates, Profile steel, Bar thiab Pipes - steel qib rooj raws liGB 50017-2017)

Ntsiab Lus |
| Q355B/C/D/E/F | S355JR/J0/J2/K2/NL | A572 Gr.50 / A992 | Qtxhais tau tias Yield Strength;355qhia qhov tsawg kawg nkaus tawm lub zog hauv MPa. Qhov no yog qib ntau tshaj plaws rau cov qauv siv dav dav. Suffixes (B, C, D, E, F) qhia txog kev ua kom muaj zog toughness ntawm qhov kub thiab txias. |
| Q235B | S235 JR | A36 | Qib tseem ceeb rau cov teeb pom kev zoo thiab cov ntsiab lus thib ob. |
| q355j ua | S355N/M, J2/J4 | A572 Gr.50 (nrog txhim kho toughness) | GJ= Siab-Kev Ua Haujlwm Zoo Tshaj Plaws rau cov tsev. Muab kev txhim kho toughness thiab weldability rau seismic lossis loj - ncua kev siv. |
| Q355q | S355J0 / J2 (EN 10025-6) | ASTM A709 Gr.50 Cov Lus Qhia | q = Daim ntawv thov choj. Tshwj xeeb optimized rau dynamic loads thiab weldability nyob rau hauv choj kev tsim kho. |
| Q355NH (GNH) | S355J0W / J2W (EN 10025-5) | ASTM A588 Gr.A/B | NH= Weathering Steel. Ua kom ruaj khov xeb patina rau superior atmospheric corrosion kuj. GNHtxhais tau tias High corrosion kuj |
| Q460C/D/E | S460N/M/L | a572g 65 | Siab - qib zog rau cov khoom hnyav hnyav. Suffixes (C, D, E, F) qhia txog kev ua kom muaj zog toughness theem ntawm qis kub. |
Lus ceeb toom ntawm Qib Zoo:Cov tsiaj ntawv tom qab (B, C, D, E, F) hauv Suav qib sib raug ncaj qha raucuam tshuam toughnessthiab ntsuas qhov kub thiab txias, piv rau "JR," "J0," "J2," "K2" cov qauv hauv EN cov qauv thiab tau teev Charpy V-tus nqi qis hauv ASTM cov qauv.
Ua pov thawj nyob rau hauv Loj -Sale National Development
Tuam Tshoj lub xyoo caum ntawm kev loj hlob sai, uas tau tsav los ntawm kev ruaj khov loj - cov cuab yeej cuab tam peev, tau tsim los ntawm cov txheej txheem steel qib no - ua qhov "rov qab" ntawm nws qhov kev hloov kho tshiab. Los ntawm cov ntaub ntawv-span Hong Kong-Zhuhai-Macao Choj thiab thoob plaws lub tebchaws siab- kev tsheb ciav hlau ceev mus rau ultra- siab- cov phiaj xwm hluav taws xob thiab thaj chaw skyscrapers, cov ntaub ntawv no tau raug lees paub nyob rau hauv lub ntiaj teb xav tau tshaj plaws thiab ntau txoj haujlwm thoob plaws txhua qhov. Cov haujlwm tseem ceeb: kev thauj mus los, hluav taws xob, thiab kev loj hlob hauv nroog.
Vim li cas thiaj xaiv Suav Cov Qauv Hlau rau International Projects?
- Kev Ua Tau Zoo & Kev Ua Tau Zoo:Qhov sib npaug saum toj no tsis yog theoretical xwb. Cov tuam txhab suav ua lag luam tsim cov kev tswj hwm nruj (feem ntau tau lees paub rau ISO 9001, EN 10204 3.1/3.2). Peb pab neeg ua haujlwm engineering muaj kev txawj ntse hauv kev tsim nrog GB steels thiab ua kom muaj kev ua raws li cov qauv tsim xws li AISC (US), EN 1090 (EU), AS 4100 (Australia), thiab GOST (Russia), ua kom yooj yim seamless project ua tiav.
- Unmatched Supply Chain Efficiency & Cost Competitiveness:Raws li lub ntiaj teb tus loj tshaj plaws steel tsim, Tuam Tshoj muaj unparalleled kev lag luam ntawm nplai.
- Tshuag Muaj:Cov qhab-nees thiab ntu tau npaj tau los ntawm cov khoom lag luam, ua kom cov khoom xa tuaj rau cov nroj tsuag fabrication hauv 1-2 hnub.
- Production Flexibility:Rau customized profiles los yog loj project ntim, mills muaj kev txhim khu kev qha txhuas lub sij hawm ntawm 35-50 hnub, kev txhawb los ntawm cov chaw nres nkoj muaj txiaj ntsig zoo.
- Comprehensive Product Ecosystem:Tshaj li cov khoom siv hauv paus, Tuam Tshoj muab cov saw hlau sib xyaw ua ke rau txhua yam khoom siv sib xws -fabricated kev sib txuas, hluav taws kub- tiv taus (FR) coatings, weathering solutions, thiab welded sections -tag nrho nyob rau hauv ib tug coherent standard system, simplifying procurement thiab zoo tswj.

Cov lus nug ntawm seb Suav cov qauv steel qib tuaj yeem hloov cov khoom sib npaug ntawm Asmeskas lossis European yog txiav txim siab los ntawm kev xyaum ua haujlwm thoob ntiaj teb: Yog. Lawv muab kev sib npaug ntawm kev ua tau zoo, kev tswj xyuas kom zoo, muaj txiaj ntsig zoo ntawm kev lag luam, thiab cov khoom lag luam kev ntseeg tau yug los ntawm lub ntiaj teb loj tshaj plaws thiab muaj kev paub txog kev tsim kho kev lag luam. Rau cov haujlwm thoob ntiaj teb, lawv sawv cev rau cov tswv yim, tus nqi - kev xaiv tau zoo yam tsis muaj kev cuam tshuam txog kev nyab xeeb lossis kev ua haujlwm.
Yog xav paub ntxiv txog qhov sib npaug ntawm cov qauv bolts, thov tiv taujpeb cov engineers muag khoom. Ua tsaug.
