In contrast to structural steel, rebar steel grades are not harmonized yet across Europe, each country having their own national standards. However, some standardization of specification and testing methods exist under EN 10080 and EN ISO 15630: BS EN 10080: Steel for the reinforcement of concrete. Weldable reinforcing steel. General. (2005)
The EN 10080: Steel for the reinforcement of concrete is a European Standard. This standard is referenced by EN 1992 . This standard specifies general requirements and definitions for performance characteristics of steel reinforcement suitable for welding, which is used for reinforcement of concrete structures, supplied as finished products:
The list ranks steelmakers by volume of steel production in millions of tons over time and includes all steelmakers with production over 10 million in 2021. The World Steel Association features a list from its members every year. Due to mergers, year-to-year figures for some producers are not comparable. Not all steel is the same. Some steel is ...
Characteristics – Generally consisting of portland cement, water, construction aggregate (coarse and fine), and steel reinforcing bars , concrete is cheaper in comparison to structural steel. Strength – Concrete is a composite material with relatively high compressive strength properties, but lacking in tensile strength/ductility.
Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.
Steel offers high tensile and shear strength to make up for what concrete lacks. Steel behaves similarly to concrete in changing environments, which means it will shrink and expand with concrete, helping avoid cracking. Rebar is the most common form of concrete reinforcement. It is typically made from steel, manufactured with ribbing to bond ...
A steel fixer with column reinforcement steel Fixing reinforcement for foundations and walls of sewage pump station in Sacramento, California. A steel fixer (UK, ironworker or "rod buster" in the United States) is a tradesman who positions and secures steel reinforcing bars, also known as rebar, and steel mesh used in reinforced concrete on construction projects.
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
