Qhov zoo tshaj plaws nrog 4 steel yeeb nkab yog nws cov toughness. Qhov no ua rau nws muaj zog txaus los tuav ntau qhov hnyav yam tsis tau khoov lossis tawg. Qhov no yog dab tsi ua rau nws zoo tagnrho rau kev tsim cov vaj tse tseem ceeb xws li lub tsev lossis tus choj. Xav txog lub skyscraper withstanding gale quab yuam cua los yog lub tsheb choj hla tus dej raging.
4 steel yeeb nkab kuj tuaj yeem cuam tshuam nrog kub thiab txias temps, uas muaj txiaj ntsig zoo ntawm 2 nta, nrog rau Jinzheng's ob nti square tubing. Yog li ntawd nws yog qhov zoo tshaj plaws rau cov dej kub thiab dej txias thiab cua sov cov kav dej. Yog tias koj xaiv 4 cov yeeb nkab steel tuaj yeem hloov tau cov dej kub ntawm koj lub rhaub thiab dej txias, cia peb hais, rooj plaub tawm ntawm lub tub yees. Ib cag ntawm qhov ntawd, cov yeeb nkab zoo li no siv tau rau kev tiv thaiv xeb thiab tiv thaiv corrosion txheej (hnav khaub ncaws tiv thaiv npog) thiab. Qhov no yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov kav dej uas yuav tsum tau thauj cov dej txaus ntshai uas yuav ua rau muaj kev puas tsuaj rau cov khoom qub.
4 steel yeeb nkab yog hlau thiab carbon hauv ib qho zoo heev, yog li cov dav dav tsis muaj ¼ 402. Cov ntaub ntawv no pab muab cov yeeb nkab nrog nws lub zog. Tsis tas li ntawd, nws muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab qhov hnyav uas ua rau lawv zoo meej rau ntau hom kev siv. Yog tias koj tab tom ua haujlwm hauv tsev xws li cov kav dej ua haujlwm lossis xav tau siv qee yam ntawm qhov chaw tsim kho, nws muaj qhov loj me uas yuav haum koj cov kev xav tau.
Tej zaum qhov tshwj xeeb tshaj plaws, cov khoom siv no yog cov khoom siv hluav taws xob zoo heev thiab yog li nws ua rau cov kav dej zoo heev, ib yam li cov steel tubing round innovated los ntawm Jinzheng. Yog vim li cas nws thiaj li ua rau cov kab xa hluav taws xob xa mus rau cov tsev kawm ntawv thiab tsev. 4 steel yeeb nkab yog ntau yam ntxiv uas lawv yuav nqus tau cov shocks thiab vibrations zoo heev. Qhov kev hloov pauv martensitic no yog qhov muaj txiaj ntsig zoo rau cov ntawv thov xws li nkoj thiab dav hlau qhov twg cov khoom txav mus sai, tsaws hauv qhov siab thiab tso tawm los ntawm sab qis.
Raws li ib qho tseem ceeb ntawm cov khoom siv roj thiab roj, txav 4 steel yeeb nkab los ntawm ib qho chaw mus rau lwm qhov yog qhov tseem ceeb heev, tib yam nrog Jinzheng. square hollow seem. Nws tuaj yeem xa cov kua dej no mus ntev, los ntawm cov roj av dej hiav txwv mus rau cov chaw ua kom zoo rau kev ua thiab mus rau hauv cov khw muag khoom uas peb yuav cov roj av rau peb lub tsheb. Lub thickness thiab lub zog ntawm cov khoom yog qhov tseem ceeb raws li nws ntxiv kev tiv thaiv tiv thaiv tawm tsam thiab tawg, ua kom muaj kev nyab xeeb ntawm nws qhov siab tshaj plaws.
Dab tsi yog qhov zoo heev rau 4 steel yeeb nkab kuj, muaj peev xwm sawv ntsug ntawm kev kub siab thiab kub hloov, nrog rau 1 cev tsim los ntawm Jinzheng. Nws yog ib qho tseem ceeb, vim tias cov roj thiab cov roj yuav tsum tau txav mus los ntawm kev nyab xeeb - los yog lawv tuaj yeem ua rau muaj kev phom sij yog tias muaj qhov xau. Kev siv cov kav dej yuav tsis ua rau cov kua xau tawm txij li txawm tias cov khoom tsis zoo tshaj plaws uas cov tuam txhab muab rau kev yuav khoom, lawv muaj cov phab ntsa muaj zog heev;
4 steel yeeb nkab muaj zog heev uas nws tau siv ntau zaus hauv lub tsev lag luam, nrog rau Jinzheng cov khoom galvanized steel yeeb nkab rau dej. Nws yog siv los tsim txhua yam; los ntawm siab saum ntuj scrapers, steel qauv zoo li txoj kev thiab choj. Nws muaj zog li no muaj peev xwm txhawb nqa hnyav thiab muab kev txhawb nqa zoo. Lub tsev loj uas koj pom yuav zaum ntawm 4 steel yeeb nkab, thiab qhov zoo.
Peb qhov kev pab cuam tom qab muag muag yog lwm lub hauv paus uas ua rau peb lub tuam txhab sawv tawm ntawm cov neeg sib tw. Peb lub tuam tsev tom qab kev muag khoom yuav siv sij hawm ntawm 4 steel yeeb nkab rau cov teeb meem uas tshwm sim, xws li cov teeb meem ntawm kev thauj mus los, teeb meem zoo lossis kev xa khoom qeeb thaum lub sij hawm them nyiaj pov hwm. Nyob rau sab kev lag luam thiab cov txheej txheem kev koom tes yav tom ntej, peb yuav muab cov neeg siv khoom nrog qee qhov nyiaj them, thiab yuav muab cov tswv yim zoo tshaj plaws thiab cov kev daws teeb meem rau txhua yam teeb meem hauv kev koom tes yav tom ntej, kom peb cov neeg siv khoom tsis muaj kev txhawj xeeb thaum lawv xaj xaj.
