Thaum ntxov li 1883, L. Seamen ntawm Tebchaws Meskas tau thov daim ntawv pov thawj rau lub tshuab dov rau dov H-beams. Hom dov zeb no siv thawj peb-cov menyuam ntu steel dov zeb thiab ntxiv ib daim ntawv qhia tshwj xeeb rau yob H-section steel nrog txoj kab nqes loj dua rau sab hauv ntawm lub flange. Qhov no yog qhov ntxov tshaj plaws dov H-beam. Nyob rau hauv 1902, lub teb chaws Yelemees tau tsim lub ntiaj teb thawj muaj H-beam dov zeb nrog rotating ntsug rollers thiab ib tug cais ntug-rolling kawg ncej. Qhov tshwm sim ntawm no dov zeb nteg rau hauv daim ntawv ntawm H-beam dov zeb. Kev tsim kho ntawm universal dov zeb tuaj yeem muab faib ua 3 theem. Ua ntej xyoo 1950, nws yog thawj theem. Qhov thib ob theem yog los ntawm 1950 mus rau 1970, thaum universal dov mills tsim sai heev nyob rau hauv kom muaj nuj nqis. Txij li xyoo 1970, vim muaj kev vam meej ntawm kev siv tshuab computer hauv kev lag luam, cov txheej txheem dov thiab dov zeb qauv tau txhim kho ntxiv. Lub teb chaws thoob ntiaj teb tau tsim ntau yam tshiab universal dov mills. Kev tsim kho ntawm universal dov mills tau nkag mus rau theem thib peb, thiab tag nrho txuas ntxiv universal dov mills tau tshwm sim. Ntxiv rau dov H-zoo li tus hlau, kev siv universal dov mills tau nthuav dav ntau lawm ntau yam rau yob rails, channel steels, lub kaum sab xis steels, ca steels thiab steel piles, uas tau coj txog kev loj hlob nyob rau hauv seem steel ntau lawm technology.
Kev txiav txim siab los ntawm qhov xwm txheej hauv cov teb chaws uas muaj kev lag luam, qhov tshwm sim ntawm H-shaped steel tau ua rau muaj kev hloov pauv loj ntawm cov ntaub ntawv siv nyob rau hauv peb cov qauv loj ntawm I-beams, channel steels thiab lub kaum sab xis steels. Los ntawm 1973, Nyiv lub H-beam ntau lawm tau pib ua thawj zaug ntawm cov qauv steel, suav txog 45% ntawm tag nrho cov seem steel ntau lawm. Qhov kev faib ua feem ntawm cov qauv hlau nyob rau hauv lwm lub teb chaws industrially tsim muaj qhov xwm txheej zoo sib xws. Raws li kev txheeb cais los ntawm ntau lub teb chaws tsim cov hlau loj, txij li xyoo 1980, cov khoom tsim tawm ntawm H-shaped steel tau suav txog kwv yees li 4% txog 7% ntawm tag nrho cov hlau tsim.
Los ntawm 1990, muaj ntau tshaj 70 H-beam dov mills nyob rau hauv lub ntiaj teb no. Lub teb chaws nrog cov khoom loj tshaj plaws thiab kev siv H-shaped steel yog Nyiv, uas tau mus txog ntau dua 9 lab tons hauv xyoo 1991. Hais txog ntau yam, ntxiv rau cov khoom siv H-shaped, muaj corrugated web H-shaped steel nrog corrugated. webs, H-shaped steel nrog tsa cov qauv nyob rau sab nraud ntawm flange, thiab huab cua-resistant H-shaped steel kom tau raws li cov kev xav tau ntawm lub tsev cov khoom nyob rau hauv ntau yam tshwj xeeb tej yam kev mob. xav tau. H-shaped steel nrog lub web qhov siab ntawm 600 mus rau 1200mm yog welded nrog tuab tiaj tiaj steel nrog ntse fab (10 mus rau 50mm × 250 mus rau 1200mm). Tshiab H-beams thiab tuab tiaj tus hlau nrog cov kaum ntse ntse tuaj yeem ua rau ntawm universal tandem dov zeb.
Tuam Tshoj tus H-shaped steel ntau lawm pib nyob rau hauv 1970s. Lub sijhawm ntawd, me me ntawm H-shaped steel nrog lub vev xaib qhov siab ntawm 300mm tau tsim nyob rau hauv Baotou, Inner Mongolia, los ntawm kev siv cov kab hluav taws xob zoo tib yam rolling zeb thiab ntxiv ib txoj kab ntsug ntsug kom tau raws li qhov xav tau ceev. Tom qab ntawd, cov chaw tsim khoom hlau thiab cov chaw tsim choj hauv Wuhan, Shanghai, Tangshan, Baoji, Shanhaiguan thiab lwm qhov chaw tuaj yeem tsim cov welded H-beams. Tuam Tshoj tus thawj dov H-beam ntau lawm kab tau muab tso rau hauv Ma'anshan, Anhui nyob rau hauv 1991. Cov kab ntau lawm muaj ib txheej ntawm reversible universal ntug-dov kawg units thiab ib tug universal xov zeb. Txais tos ntev ntev txias thiab ntev ntev straightening txheej txheem. Raws li tus qauv tsim, beam-shaped H-shaped steel nrog lub web qhov siab tsawg dua 200mm thiab kem-shaped H-shaped steel nrog lub web qhov siab tsawg dua 150mm tuaj yeem tsim tau raws li cov qauv thoob ntiaj teb.
