Product Detail

Khoom cim npe

Galvanized square rectangle steel tube Nws yog lub npe rau cov yeeb nkab square thiab cov yeeb nkab duab plaub, uas yog cov yeeb nkab nrog tib sab ntev.Nws yog ua los ntawm sawb hlau tom qab ua tiav thiab dov.Feem ntau, lub sawb yog unpacked, leveled, crimped thiab welded rau hauv ib puag ncig raj, uas yog dov mus rau hauv ib lub raj square thiab ces txiav mus rau hauv qhov ntev yuav tsum tau.Feem ntau 50 sticks rau ib pob.Kuj hu ua square thiab rectangular txias tsim hollow steel, hu ua square yeeb nkab thiab cov yeeb nkab duab plaub, code F thiab J feem.

Galvanized Square Rectangle Steel Tube Cov Ntawv

1.Galvanized square duab plaub steel raj, qhov tso cai sib txawv ntawm phab ntsa tuab yuav tsum tsis pub tshaj qhov zoo lossis qhov tsis zoo 10% ntawm nominal phab ntsa thickness thaum phab ntsa thickness tsawg dua 10 hli, thiab qhov zoo lossis qhov tsis zoo 8% ntawm nominal phab ntsa thickness thaum phab ntsa thickness yog ntau tshaj 10 hli, tshwj tsis yog rau phab ntsa thickness ntawm lub ces kaum thiab weld cheeb tsam.

2.Galvanized square duab plaub steel tube, Lub sij hawm xa khoom ntev yog 4000mm-12000mm, nrog rau 6000mm thiab 12000mm feem ntau.Square lub raj tso cai xa khoom tsis pub tsawg dua 2000mm luv thiab cov khoom tsis sib xws, tuaj yeem xa tuaj rau hauv daim ntawv ntawm lub raj interface, tab sis cov neeg siv khoom yuav tsum tshem tawm lub raj txuas thaum siv.Qhov hnyav ntawm cov khoom luv luv thiab ntev tsis tu ncua yuav tsum tsis pub tshaj 5% ntawm tag nrho cov khoom xa tuaj, thiab rau cov raj square square nrog qhov theoretical hnyav tshaj 20kg / m yuav tsum tsis pub tshaj 10% ntawm tag nrho cov khoom xa tuaj.

3.Galvanized square duab plaub steel raj, qhov khoov degree yuav tsum tsis txhob ntau tshaj 2 hli ib meter, thiab tag nrho cov dabtsi yog khoov degree yuav tsum tsis txhob ntau tshaj 0.2% ntawm tag nrho cov ntev.
