DIN 1628 St52.4 St 44.4 St37.4 Welded Steel Tubes

GNEE Group tau tshwj xeeb hauv kev tsim cov DIN 1628 steel kav rau 16 xyoo. Peb muab DIN 1628 ST37.4 welded kav, DIN 1628 ST44.4 welded kav, thiab DIN 1628 ST52.4 welded kav. Peb DIN 1628 welded kav yog tsim los siv ob qho tib si longitudinal thiab kauv seam vuam txheej txheem. DIN 1628 ST37.4, DIN 1628 ST44.4, thiab DIN 1628 ST52.4 steel kav uas tsim los ntawm GNEE Group yog tsim rau cov khoom tsim, ntim khoom, kav raj xa dej, nrog rau kev siv tshuab thiab ntsuas kev tsim khoom.

Raws li cov kws tshaj lij steel yeeb nkab chaw tsim khoom, peb tsis yog tsuas yog muab cov kav hlau zoo nkauj xwb tab sis kuj muab cov nqi sib tw thiab cov kev pabcuam tshuaj xyuas nruj. Peb tuaj yeem muab cov ntawv pov thawj kev soj ntsuam zoo rau cov kav dej steel. Yog tias koj xav kawm ntxiv, thov hu rau dawbtiv tauj pebthaum twg los tau.
