BS 4486:1980

This standard BS 4486:1980 Specification for hot rolled and hot rolled and processed high tensile alloy steel bars for the prestressing of concrete is classified in these ICS categories:

• 77.140.15 Steels for reinforcement of concrete
• 91.080.40 Concrete structures

This British Standard specifies requirements for preferred sizes of smooth or ribbed alloy steel bars in straight lengths supplied in the hot rolled or hot rolled and processed conditions. Two nominal strength levels of steel are specified. This standard does not specify fatigue testing, this subject being included in BS 4447. Stress-corrosion testing is not specified.

Requirements for preferred sizes for smooth or ribbed alloy steel bars in straight lengths supplied in either hot rolled or hot rolled and processed conditions. Two nominal strength levels, 835 N/mm² and 1080 N/mm² subject to the processed condition.
