STEEL FOR THE REINFORCEMENT OF CONCRETE - PART 1: PLAIN BARS

1 Scope

This standard specifies technical requirements for plain bars to be used as reinforcement in concrete.

This standard covers CB240-T, CB300-T and CB400-T. The production process is at the discretion of the manufacturer.

NOTE: The first “CB” indicates reinforcing concrete. The next three digits represent the specified characteristic value of upper yield strength. The last “T” indicates plain bar.

This standard covers products delivered in straight lengths. It also applies to plain bars supplied in coil form and straightened products.

Plain bars produced from finished products, such as plates and railway rails, are excluded.
