H beam no yog ua los ntawm high- zoo carbon structural steel thiab qis- alloy steel, tsim los ntawm precision kub dov. Nrog rau tus qauv H-zoo li tus ntoo khaub lig- ntu, nws khav theeb cov kev ntxhov siab tsis sib xws, khoov zoo thiab compression tsis kam, thiab siv cov khoom siv siab. Raws li cov khoom tseem ceeb- bearing structural material nyob rau hauv kev tsim kho, choj, thiab industrial chaw, nws txhawb customization raws li thoob ntiaj teb cov qauv hauv cheeb tsam nrog tag nrho - txheej txheem kev tswj kom ua tau raws li qhov project zoo.
Core Advantages: Tsim kom muaj kev nyab xeeb ruaj khov rau cov haujlwm
High Load-Bearing Capacity: Qhov tshwj xeeb H-zoo li tus ntoo khaub lig-section tsim kom ntseeg tau zoo dua dabtsi yog khoov thiab shear tsis kam piv rau cov seem hlau. Nws txo cov khoom poob los ntawm 10% -30% raws li tib lub sijhawm thauj khoom, txo cov nqi tsim nyog;
Multi-Standard Compatibility: Tag nrho cov thoob ntiaj teb cov qauv tseem ceeb xws li GB (Q235B/Q355B/Q420), ASTM (A36/A572), JIS (SS400), thiab EN (S235JR/S355JR), yoog raws li cov kev xav tau ntawm kev lag luam sib txawv hauv Asia, South America{{9}, Pacific, Nyiv, Nyiv, Kaus Lim Qab Teb;
Kev tsim kho yooj yim: Siab precision ntawm qhov ntev ntawm cov txheej txheem ua kom ncaj qha txiav, vuam, thiab sib dhos, ua kom lub sijhawm siv sijhawm luv. Nws txhawb kev hloov kho ntev ntawm 3-12m, nrog rau kev tiv thaiv- kev kho corrosion xws li kub-dip galvanizing thiab pleev xim, haum rau qhov chaw sab nraum zoov.
ASTM H Beam Chemical Composition: Cov ntsiab lus tseem ceeb
Cov tshuaj muaj pes tsawg leeg yog lub hauv paus tseem ceeb rau kev ua haujlwm ntawm ASTM H beams, cuam tshuam ncaj qha rau lawv lub zog, toughness, weldability thiab corrosion kuj. Cov hauv qab no yog cov kev xav tau ntawm cov tshuaj muaj pes tsawg leeg (feem ntau, %) ntawm cov ntsiab lus ASTM H beam qib, raws li qhov tseeb ASTM tus qauv specifications.
| ASTM Qib | Carbon (C) Tsawg dua lossis sib npaug | Silicon (Si) Tsawg dua lossis sib npaug |
Manganese (Mn) | Phosphorus (P) Tsawg dua los yog sib npaug | Sulfur (S) Tsawg dua lossis sib npaug | Lwm yam Alloy Elements |
| A36 | 0.25 | 0.40 | 0.80-1.20 | 0.04 | 0.05 | Cu Ntau dua lossis sib npaug rau 0.20 (thaum teev tseg) |
| A572 Gr50 | 0.23 | 0.40 | 0.80-1.50 | 0.04 | 0.05 | Nb: 0.005-0.05; V: 0.01-0.15 |
