Resistance kuwotcherera ali ndi makhalidwe a mkulu kupanga dzuwa, mtengo wotsika, kupulumutsa zinthu ndi zosavuta zochita zokha, choncho chimagwiritsidwa ntchito mu ndege, Azamlengalenga, mphamvu, zamagetsi, galimoto, makampani kuwala ndi magawo ena mafakitale, ndipo ndi imodzi mwa njira zofunika kuwotcherera .Kusiyana kwakukulu pakati pa chitoliro chachitsulo cha ERW ndi chitoliro chachitsulo chosasunthika ndikuti ERW ili ndi weld, yomwe ilinso chinsinsi cha khalidwe la chitoliro cha ERW.ERW chitoliro ndi "mkulu pafupipafupi kukana welded chitsulo chitoliro", amene ndi osiyana ndi ndondomeko kuwotcherera wamba welded chitoliro.The weld amapangidwa ndi kusungunula zitsulo m'munsi mwa zitsulo Mzere thupi, ndi mphamvu yake makina ndi bwino kuposa wamba welded chitoliro.
1) Phindu Lachuma: Chitoliro chachitsulo cha ERW ndi chotsika mtengo kuposa chitoliro chachitsulo chosasokonekera.
2) Kusamalitsa Kwambiri: Chitoliro chachitsulo cha ERW chimakhala ndi kulolerana kwapafupi kwa makulidwe a khoma poyerekeza ndi chitoliro chopanda chitsulo.
ERW zitsulo chitoliro chimagwiritsidwa ntchito mu ndege, Azamlengalenga, mphamvu, zamagetsi, galimoto, makampani kuwala ndi magawo ena mafakitale.Chitoliro chachitsulo cha ERW chimagwiritsidwa ntchito kunyamula mafuta, gasi ndi zinthu zina zamadzimadzi, zomwe zimatha kukwaniritsa zofunikira zosiyanasiyana zamphamvu komanso zotsika.Pakalipano, imagwira ntchito yofunika kwambiri pa ntchito ya mapaipi oyendetsa dziko lapansi.
