Vim li cas S355JR H Beams yog qhov kev xaiv zoo tshaj plaws rau ntau yam -Level Parking Structures
1. S355JR H kab teeb muaj lub zog tawm los Ntau dua lossis sib npaug ntawm 355 MPa, kwv yees li 30% siab dua S275JR, tso cai rau kev siv cov ntoo hla me me - ntu thiab nyias dua - cov kab teeb thiab cov kab, txo cov khoom hnyav dua li 15%, txo cov nqi nres tsheb.
2. S355JR H Structural Steel Beams tau zoo- tswj cov pa sib npaug, tuaj yeem tiv taus siab - lub zog vuam thiab CNC xuas nrig ntaus, thiab tsim nyog rau txoj kev sib txuas "beam-kem" thiab cov qauv kev sib dhos ntawm ntau - theem chaw nres tsheb, ua kom muaj kev pheej hmoo ntawm kev sib tsoo.
S355JR H qauv steel kab teeb
3. Kub Rolled S355JR H Beams muaj elongation Ntau dua los yog sib npaug li 20% thiab zoo heev cuam tshuam toughness ntawm chav tsev kub, muaj peev xwm nqus tau siab - zaus cuam tshuam los ntawm lub tsheb nres, tig, thiab lifting machinery, ho ncua lub neej kev pab cuam ntawm cov qauv.
Txhua pawg ntawm S355JR HEB kab teeb los nrog EN 10204 3.1 MTC Hoobkas kuaj daim ntawv pov thawj, tag nrho ua raws li EN 10025-2. Cov tshuaj lom neeg muaj pes tsawg leeg, lub zog tawm los, lub zog tensile, thiab kev cuam tshuam toughness yog guaranteed, ua kom ntseeg tau zoo rau cov haujlwm engineering thoob ntiaj teb.
Project Case Piv txwv
-
Middle East High-Rise Multi-Level Parking Project
-
15-zaj dab neeg lub tsev loj nrog ntau theem chaw nres tsheb.
-
Muab 2,500 tons ntawm S355JR HEB steel beams.
Siv cov nqaj me me thiab cov kab ke txo qis kev siv steel tag nrho thaum txhim kho kev thauj khoom -cov kabmob muaj peev xwm.
- Northern Europe Coastal Chaw nres nkoj Choj Chaw nres tsheb
Nyob rau hauv qis - qhov kub thiab txias, siab - cov av noo; tus choj yog raug rau dynamic tsheb thauj khoom.
Pom zoo siv S355JR H kab teeb, tau ntawv pov thawj rau qis- qhov kub thiab txias cuam tshuam, ua kom muaj kev nyab xeeb thiab kev ntseeg siab nyob rau hauv huab cua txias.
S355JR H kab teeb yog qhov siab -kev ua tau zoo, txhim khu kev qha, thiab tus nqi- muaj txiaj ntsig zoo rau ntau - theem chaw nres tsheb. Lawv lub zog muaj zog, zoo weldability, thiab ua raws li cov qauv thoob ntiaj teb ua rau lawv haum rau ntau lub nroog thiab chaw nres tsheb.
Los ntawm kev xaiv HEA, HEB, lossis HEM cov ntaub ntawv tsim nyog, cov kws tsim khoom tuaj yeem ua tiav qhov txiaj ntsig zoo ntawm kev nyab xeeb thiab cov nqi khoom siv, ua rau kev tsim kho kom zoo, ruaj khov, thiab kev lag luam ntau - theem chaw nres tsheb.
