Description / Abstract:

This specification covers deformed and plain billet-steel concrete-reinforcement bars in cut lengths or coils. A deformed bar is defined as a bar that is intended for use as reinforcement in reinforced concrete construction. The surface of the bar is provided with lugs or protrusions (hereinafter called deformations) which inhibit longitudinal movement of the bar relative to the concrete which surrounds the bar in such construction and conform to the provisions of this specification. The standard sizes and dimensions of deformed bars and their number designations shall be those listed in Table 1.

NOTE I—For coils of deformed bars, the capacity of industrial equipment limits the maximum bar size that can be straightened.

Bars are of three minimum yield levels: namely, 300, 400, and 500 MPa, designated as Grades 300, 400, and 500, respectively.

Deformed bars are listed in eight sizes, from size No. 10 to size No. 55.

Hot-rolled plain rounds, in sizes up to and including 50 mm in diameter in coils or cut lengths, when specified for dowels, spirals, and structural ties or supports, shall be furnished under this specification in Grades 300, 400, and 500 (Note 2). For bending properties, test provisions of the nearest nominal diameter deformed bar size shall apply. Those requirements providing for deformations and marking shall not be applicable.

NOTE 2—The weight for plain rounds smaller than IO mm in diameter shall be computed on the basis of the size in Specification A 510M.

The weldability of the steel is not part of this specification. 

NOTE 3—This specification is the metnc companion to Specification specification. A 615.
