Marka ay timaado qaabka bar wareega, waxaa sida caadiga ah loo isticmaalaa codsiyada halkaas oo xoog sare iyo caabbinta daxalka wanaagsan loo baahan yahay. Awoodda ay u leedahay in ay u adkeyso heerkulka sare waxay ka dhigaysaa mid ku haboon in loo isticmaalo goobaha meelaha kale ee birta kale aysan si fiican u shaqeyn karin. Qaabka wareega wareega ee 420 Steel Steel waxaa loo isticmaalaa ujeedooyin kala duwan, oo ay ku jiraan shafka, faashashka, qalabka, iyo qaybaha kale ee u baahan xoog sare iyo daxal iska caabin. Waa lagama maarmaan in la hubiyo in qeexitaannada bar-wareega ay la kulmaan heerarka loo baahan yahay ee codsigaaga gaarka ah.
