JIS G3466 STK490 yog dab tsi?
CovJIS G3466specification standardizes carbon steel square thiab rectangular raj siv rau kev tsim qauv.
TSI 490:Sawv cev rau qib siab -tensile hauv tus qauv no. Lub "490" txhais tau hais tias qhov tsawg kawg nkaus tensile lub zog ntawm490 MPa ua, muab kev thauj khoom ntau dua -cov kabmob muaj peev xwm piv rau cov qib qis xws li STK400. Qhov no ua rau cov kws tsim qauv qhia cov phab ntsa nyias nyias thiab sib dua steel profiles yam tsis muaj kev cuam tshuam cov qauv kev nyab xeeb.
Ntsiab nta & Engineering Advantages
1. Superior Strength-rau-Qhov hnyav piv
Nrog rau qhov tsawg kawg nkaus lub zog ntawm 325 MPa thiab tensile zog ntawm 490 MPa, STK490 hlab tso cai rau optimized structural configurations. Txo qhov hnyav tag nrho cov hlau hnyav txo cov nqi yuav khoom, txo qis hauv lub hauv paus, thiab txo cov nqi xa khoom thoob ntiaj teb.
2. Zoo Torsional thiab khoov Resistance
Qhov kaw, symmetrical geometric profile ntawm square thiab rectangular hollow seem (SHS/RHS) ua haujlwm ntau- kev taw qhia kev thauj khoom tau zoo dua li cov qauv qhib steel (xws li I-beams lossis kaum hlau). Qhov no ua rau lawv zoo heev rau cov kab thiab trusses.
3. Zoo Weldability & Fabricability
Txawm hais tias nws lub zog siab, cov tshuaj muaj pes tsawg leeg ntawm STK490 yog qhov sib npaug kom tswj tau qhov siab weldability. Fabricators tau yooj yim txiav, xyaum, khoov, thiab vuam cov hlab no siv cov txheej txheem kev cob qhia, txuag lub sijhawm ua haujlwm zoo.
4. High Aesthetic Zoo
Featuring flat surfaces, uniform corner radii, and smooth finishes, our JIS G3466 sections are zoo tagnrho rau Architecturally Exposed Structural Steel (AESS) qhov twg steel moj khaum tseem pom rau pej xeem.

Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov txawv ntawm STK400 thiab STK490 raws li JIS G3466?
A: Qhov sib txawv tseem ceeb yogtensile thiab yield zog. STK400 muaj lub zog tensile yam tsawg kawg nkaus ntawm 400 MPa, thaum STK490 boasts lub zog tensile yam tsawg kawg nkaus ntawm 490 MPa. STK490 yog xaiv rau hnyav-load infrastructure, siab-nce framing, los yog ib qho kev tsim engineering uas txo qhov hnyav ntawm cov hlau yog qhov tseem ceeb.
Q: Puas yog JIS G3466 STK490 steel tubes tuaj yeem kub -dip galvanized?
A: Yog, kiag li. Peb muab hwmKub-Dip Galvanizing (HDG)Ua raws li cov qauv thoob ntiaj teb xws li EN ISO 1461 lossis ASTM A123. Kev tswj cov chemistry ntawm peb cov hlau ua kom zoo zinc adhesion, tiv thaiv cov hlab los ntawm hnyav, av noo, lossis ntug hiav txwv atmospheric corrosion rau ntau xyoo.
Q: Koj yuav tiv thaiv cov seem hollow li cas los ntawm kev puas tsuaj thaum lub sij hawm thauj dej hiav txwv?
A: Txhawm rau tiv thaiv koj cov khoom siv thaum caij nkoj mus ntev, cov raj tau ruaj khov rau hauv nruj hexagonal bundles siv siab - tensile steel strapping. Txhawm rau tiv thaiv ntau tshaj plaws ntawm hiav txwv- ntsev av noo, peb tuaj yeem siv cov tshuaj tiv thaiv - xeb kua roj vanish txheej thiab qhwv cov pob hauv cov ntaub ntawv tsis muaj dej tsis zoo PVC.
Q: Koj puas txhawb nqa kev cai ntev thiab thib peb -kev kuaj xyuas tog?
A: Yog. Peb tuaj yeem txiav cov raj kom meej qhov ntev ntawm daim ntawv qhia kom txo tau koj ntawm - qhov chaw tsim khoom pov tseg. Peb kuj zoo siab txais tos thib peb - tog tshuaj ntsuam xyuas (TPI) tuam txhab xws li SGS, Bureau Veritas (BV), los yog TÜV los xyuas qhov ntev ntawm cov khoom, tshuaj ntsuam xyuas, thiab ntim ua ntej xa.
