BS4449 Steel Reinforcement Rebar

BS4449 is yet another deformed steel bar standard. It is also differentiated as per European standards. When it comes to manufacturing, the steel bars falling in this standard are also hot rolled, which means that they are also used for general purposes, i.e. in common construction projects. These deformed bars are also available between 12 mm to 30 mm diameter size. And the common lengths that they are available in are 9 m and 12 m. Such bars are widely used in houses, bridges, roads, especially railways and other civil engineering.
