BS4449 Steel Reinforcement Rebar

The differences between the, B and C designations are complex and related to structural tolerances. For steel mesh products, B500A grade steel is usually used, and for steel bars, B500B grade steel is used. B500C steel is rarely required, and it is always worthwhile for structural engineers to check whether B500B grade steel can be used instead of B500C, because B500C usually has a significant cost overhead.

BS4449 Steel Reinforcement Rebar Description

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. Though, it might vary highly.
