Ua kev zoo siab rau nws txoj kev ua tau zoo, kev ua haujlwm zoo heev, thiab kev sib raug zoo nrog cov haujlwm thoob ntiaj teb, nws ua haujlwm tseem ceeb rau kev lag luam, thaj chaw, thiab cov teeb pom kev lag luam, ua tau raws li ASTM A36 cov kev cai.
ASTM A572 Qib 50: A siab -lub zog qis- alloy (HSLA) qib steel nrog qhov tsawg kawg nkaus lub zog ntawm 345MPa thiab tensile zog ntawm 485-620MPa. Engineered rau superior zog-rau- qhov hnyav piv (38% siab zog yield zog dua A36), nws optimizes cov khoom siv nyob rau hauv hnyav-lub luag hauj lwm tsim, loj- ncua choj, thiab high-sawv vaj tse, ua raws li ASTM A572 qauv.
Txhua qib tau txais kev lees paub zoo, suav nrog kev tshuaj xyuas tshuaj lom neeg, kev ntsuas tensile, kev sim khoov, thiab kev ntsuas kev cuam tshuam, nrog rau Cov Ntawv Pov Thawj Xeem (MTCs) muab los lees paub ua raws li qhov project- cov qauv tshwj xeeb.
I/H-Beam Structural Advantages & Kub-Rolled Precision
Ob qho kuv-beam thiab H-beam profiles leverage tus ntoo khaub lig optimized-sectional tsim, nrog rau cov kev pab cuam tseem ceeb txhim kho los ntawm qhov kub- dov manufacturing txheej txheem:
Tus Qauv Tsim: Parallel flanges zoo faib cov tensile thiab compressive zog, thaum lub hauv paus web tiv thaiv shear loads, txo deflection thiab deformation nyob rau hauv zoo li qub, dynamic, los yog seismic stresses. H-beams feature dav flanges dua li ib txwm kuv-beams, muab superior dabtsi yog khoov nruj thiab stability rau loj -span daim ntaub ntawv, thaum kuv -beams excel nyob rau hauv qhov chaw- txwv scenarios vim lawv slimmer profile.
Kub-Rolled Txheej Txheem: Ua los ntawm kev tswj qhov kub thiab txias (1,100-1,250 degree), cov txheej txheem ua kom zoo dua cov hlau cov qauv, tshem tawm cov teeb meem sab hauv (xws li, porosity, microcracks), thiab ua kom cov khoom sib xws. Qhov no ua rau muaj qhov ua tau zoo ntawm qhov ntev (flange dav dav, lub vev xaib tuab, ncaj), lub ntsej muag du, thiab txhim kho kev qaug zog tiv thaiv- tseem ceeb rau lub sijhawm ntev - cov qauv kev ncaj ncees. Qhov kub- dov microstructure kuj tseem khaws cia cov ductility thiab weldability, ua kom yooj yim seamless fabrication (txiav, drilling, vuam) thiab sib dhos ntawm qhov chaw.
Application Scope & Engineering Versatility
Qhov ntau-qib I/H- kab teeb no yog tsim los rau ntau hom kev siv thoob ntiaj teb, ua raws li cov cai hauv cheeb tsam thiab tsim nyog rau:
Kev tsim kho vaj tse: Pem teb kab teeb, ru tsev trusses, thiab cov thav duab rau cov tsev, cov tsev, thiab cov tsev nyob (Q235, SS400, A36 nrog I-beams rau cov qauv loads).
Commercial & Industrial Buildings: Main girders, columns, and floor systems for offices, shopping malls, warehouses, and manufacturing plants (Q355, ASTM A572 Grade 50 with H-beams for heavy loads and large spans).
Infrastructure Projects: Choj, hla hla, kev txhawb nqa kev tsheb ciav hlau, thiab kev tsim kho vaj tse hauv vaj tse (ASTM A572 Qib 50, Q355 rau siab- kev ntxhov siab, siab - ncua kev xav tau).
Modular & Prefabricated Siv: Cov qauv tsim rau kev tawm -qhov chaw tsim khoom, ua kom muaj kev sib dhos sai, zoo ib yam, thiab txuag nqi (SS400, A36 rau kev hla- ciam teb qhov project compatibility).
Quality Assurance & Reliability
Txhua I/H-beam tau dhau los ua cov txheej txheem tswj xyuas kom ua tau raws li cov qauv thoob ntiaj teb:
Dimensional Inspection: Kev txheeb xyuas ntawm tus ntoo khaub lig-sectional dimensions, length, thiab straightness kom ua tau raws li qhov profile specifications.
Kev Ntsuas Cov Khoom Siv Tshuaj: Kev tshuaj xyuas tshuaj muaj pes tsawg leeg thiab kev siv tshuab ua haujlwm tau zoo (tensile, dabtsi yog khoov, cuam tshuam kev xeem) kom paub meej qib- cov khoom tshwj xeeb.
Tsis yog-Kev kuaj kev puas tsuaj: Ultrasonic kuaj rau qhov tsis xws luag sab hauv thiab kuaj cov khoom sib nqus rau cov kab nrib pleb, ua kom muaj kev ncaj ncees.
Traceability: Batch-MTCs tshwj xeeb (raws li EN 10204 3.1}/B, ASTM, lossis GB / JIS cov cai) muab tag nrho cov pob tshab ntawm cov khoom siv raw thiab cov txheej txheem tsim khoom.
Qhov kev cog lus tsis txaus ntseeg rau qhov ua tau zoo no ua kom cov kub -rolled carbon steel I/H-beam series muab kev ua tau zoo, kev nyab xeeb, thiab ua haujlwm ntev, ua rau nws yog ib qho tseem ceeb ntawm cov qauv tsim rau kev tsim kho thoob ntiaj teb thiab kev lag luam.
