High Quality Galvanized Power Steel Ncej Cov lus piav qhia Lub zog steel ncej yog hom tshiab ntawm cov khoom siv hluav taws xob rau kev txhim kho cov kab hluav taws xob hauv xyoo tas los no, thiab lawv yog lwm txoj hauv kev rau cov cement ncej. Lub zog steel rods yog ua los ntawm polygonal steel kav, round steel kav thiab lwm yam steels, thiab yog kho nrog kub-dip galvanizing los yog kub-txhaj tshuaj zinc (thiab zinc alloy) txheej. Qhov zoo 1.Small hneev taw rau lub zog steel ncej Cov hneev taw me me yog qhov zoo ntawm cov ncej steel. Ib txwm kis tau tus yees thiab cable ncej yees ob leeg muaj qhov tsis zoo ntawm cov hneev taw loj. Txawm li cas los xij, raws li kev lag luam kev lag luam tam sim no, cov nqi av tau nce ntau zaus, kev ua haujlwm hauv av rau kev xa hluav taws xob tau dhau los ua nyuaj, kev nqis peev tau loj dua thiab loj dua, thiab hauv qee qhov tshwj xeeb, xws li hauv nroog hauv nruab nrab, cov xwm txheej rau kev tsim kho. hluav taws xob yees tsuas yog tsis muaj. Qhov no yog vim cov ncej steel tau dhau los ua thawj qhov kev xaiv rau kev tsim hluav taws xob xa hluav taws xob. Cov ncej hlau nyob hauv ib cheeb tsam me me, feem ntau yog li 1/3 ntawm cov neeg txhawb nqa tus kheej. Nyob rau tib lub sijhawm, qhov loj me ntawm cov ncej steel yog ntau me dua li ntawm tus pej thuam, thiab qhov yuav tsum tau muaj cua kab hauv tsev kuj tseem me me. Yog li ntawd, steel ncej tuaj yeem siv dav dav. Ua tau raws li ntau yam kev cai ib puag ncig thiab txuag cov nqi av. 2.Zoo zoo nkauj ntawm steel pas nrig Qhov no yog lwm qhov zoo ntawm cov ncej steel. Hauv cov nthwv dej tam sim no ntawm kev tsim kho hauv nroog thiab kev hloov hauv nroog, txawm tias lub nroog zoo nkauj lossis tsis tau nyiam ntau thiab ntau dua los ntawm cov neeg nyob hauv. Yog li ntawd, cov kev cai rau erection ntawm lub hwj chim kab nyob rau hauv kev tsim kho hauv nroog tau nce siab thiab siab dua, uas kuj yog qhov yuav tsum tau muaj rau lawv cov kev zoo nkauj. Tshwj xeeb, qee txoj kev hauv nroog toj roob hauv pes muaj cov kev cai nruj dua hauv qhov kev hwm no, thiab cov ncej thiab cov pej thuam yog qhov nyuaj ua kom tau raws li qhov yuav tsum tau ua. Vim nws cov qauv compact thiab zoo nkauj tsos, cov pas nrig steel tuaj yeem ua tau raws li qhov xav tau ntawm kev zoo nkauj. 3.Steel ncej kev tsim kho yog yooj yim thiab ceev Yuav tsum muaj kev sib dhos ntauwd rau kev tsim cov tsoos hlau yees. Lub sijhawm tsim kho yog tib yam txawm hais tias tus pej thuam tau sib sau ua ke hauv ib qho tag nrho lossis hauv ntu. Kev tsim kho steel ncej yeej tsis tas yuav tsum muaj txheej txheem sib dhos. Koj tsuas yog yuav tsum tau nruab lub steel ncej hla caj npab thiab ua tiav tag nrho. Kev tsim kho tam sim ntawd muaj, thiab kev tsim kho nrawm nrawm dua li kev tsim cov hlau ntauwd. Feem ntau, pab pawg tsim kho tuaj yeem txhim kho 1.5 mus rau 2 lub hauv paus ntawm cov hlau ntauwd ib hnub, thiab txog 10 lub hauv paus ntawm cov ncej steel ib hnub, yog li kev siv cov ncej steel tuaj yeem txhim kho kev tsim kho. Efficiency, shorten lub sij hawm tsim kho. 4.Steel rod khoom tsis yooj yim rau raug nyiag Los ntawm ntauwd cov ntaub ntawv yeej ib txwm yog ib qho teeb meem loj uas plagued lub lag luam zoo ntawm yees. Txawm hais tias qee qhov kev ceev faj tau raug coj los ua, xws li kev txhim kho kev tiv thaiv tub sab hauv qab 6 meters, qhov teeb meem ntawm cov khoom siv ntauwd tseem tshwm sim qee lub sijhawm. Vim hais tias cov pas nrig steel yog integrally plugged los yog flanged, qhov tshwm sim ntawm qhov uas ploj lawm yog ib qho yooj yim tshem tawm, lub zais kev phom sij ntawm cov xwm txheej raug txo, thiab qib kev noj qab haus huv ntawm cov kab yog txhim kho. Ntxiv rau qhov zoo li saum toj no, lub zog steel ncej muaj qhov zoo ntawm lub voj voog luv luv thiab muaj peev xwm tiv taus kev ntxhov siab ntau dua. Specification: Daim ntawv thov:
