Technically, DOM tsis yog ib hom hlau raj, tab sis theej cov txheej txheem uas lub raj tiav lawm. Nws raug suav hais tias yog lub raj zoo, thiab feem ntau yog tsim los ntawm SAE 1020 lossis 1026 steel. Thawj theem ntawm kev tsim khoom yog zoo tib yam rau cov uas siv los ua hluav taws xob tiv thaiv welded raj, tab sis nyob rau hauv cov theem tiav tag nrho flash weld raug tshem tawm thiab lub raj yog txias los ntawm ib tug mandrel. Cov txheej txheem txias txias muab lub raj nrog qhov zoo dua qhov ntev, txhim kho qhov chaw tiav thiab qhov muaj zog weld lub zog ua tiav. DOM feem ntau yog siv tsis raug raws li "seamless raj" thaum nws yeej muaj seam (txawm tias nws yuav luag tsis pom).
