Specification for Hot Rolled and Hot Rolled and Processed High Tensile Alloy Steel Bars for the Prestressing of Concrete
Also Known As:
BS 4486:1980 is a standard that specifies the requirements for smooth or ribbed alloy steel bars used for the prestressing of concrete. It covers bars supplied in either hot rolled or hot rolled and processed conditions. The standard defines preferred sizes for these bars, which are available in two nominal strength levels: 835 N/mm² and 1080 N/mm².
The bars can be supplied in straight lengths and are specifically designed for use in prestressing applications. They are made from high tensile alloy steel, which provides excellent strength and durability. The bars are available in various diameters and have either a smooth or ribbed surface.
The standard also outlines the requirements for the processed condition, which is applicable to the higher strength level of 1080 N/mm². This includes additional processing steps that enhance the mechanical properties of the bars.
