Q:Difference between round bar and threaded steel in use.
Because steel for low alloy steel, its price is higher than that of low carbon steel, or construction units, design units, often on the general civil construction of the "practical" point of view, reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often bribed "project inspector after" to replace "Choulianghuanzhu rib steel bar, reduce the construction cost.
