Txhua yam niaj hnubtus ncejTam sim no yog ua los ntawm kub dov steel ntawm tshwj xeeb cross - paab}}} paim-}} paim hav zoov thiab bullhead rail zoo. Ib txoj kev tsheb ciav hlau yog tsim los ntawm peb ntu ntawm kev tsheb nqaj hlau, lub vev xaib thiab tag nrho cov chaw sib tw, thiab tag nrho cov siab (a), ko taw dav (b) thiab lub taub hau dav (c). Ua ke nrog lub vev xaib tuab (t), lub 4 qhov ntau thiab tsawg yog qhov ntev tag nrho rau kev faib hom kev tsheb ciav hlau.
Feem ntau cov tsheb ciav hlau tam sim no tam sim no yog tsim los ntawmKub -} rolled steelnrog ib qib 1084 lossis siab dua. Hom nruab nrab ntawm cov roj carbon steel yog tsim los ntawm cov rail hlau nrog ntuj hlau ore.
