What is the term for the steel reinforcement commonly used in concrete?

The term used for the steel reinforcement commonly employed in concrete is "Bewehrungsstahl." This German term translates directly to "reinforcing steel" in English and specifically refers to the steel bars or mesh used to strengthen and support concrete structures. Concrete, while strong in compression, is weak in tension; therefore, Bewehrungsstahl is essential to enhance its tensile strength and ensure durability under various loads and conditions.

The other suggestions, such as "Betonstahl," while similar, might cause confusion as they can refer to any type of steel used in concrete but are less specific about the reinforcing function. "Stahlträger" refers to steel beams that bear loads rather than reinforcing concrete, and "Verbundstahl" is a term that encompasses composite steel, which often pertains to materials combining steel and other substances. Thus, Bewehrungsstahl is the precise term for the steel specifically designed for reinforcing concrete.
