Description of ASTM-A1064/A1064M 2015ASTM A1064/A1064M-15aHistorical Standard: Standard Specification for Carbon-Steel Wire and Welded Wire Reinforcement, Plain and Deformed, for ConcreteASTM A1064/A1064MScope 1.1 This specification covers carbon-steel wire and welded wire reinforcement produced from hot-rolled rod to be used for the reinforcement of concrete. The steel wire is cold-worked, drawn or rolled, plain (non-deformed, as-drawn or galvanized), or deformed. Welded wire reinforcement is made from plain or deformed wire, or a combination of plain and deformed wire. Common wire sizes and dimensions are given in Table 1, Table 2, Table 3, and Table 4. Actual wire sizes are not restricted to those shown in the tables.
(A) Table 1 should be used on projects that are designed using inch-pound
units; Table 2 should be used on projects that are designed using SI units.
(B) The number following the prefix indicates the nominal cross-sectional area of the wire in square inches
multiplied by 100.
(C) For sizes other than those shown above, the Size Number shall be the number of one hundredth of a square
inch in the nominal area of the wire cross section, prefixed by the W.
(D) These sizes represent the most readily available sizes in the welded wire reinforcement industry. Other
wire sizes are available and many manufactures can produce them in 0.0015 in.2 increments.
(E) The nominal diameter is based on the nominal area of the wire.
(A) The wire sizes in Table 1 should be used on projects that are
designed using inch-pound units; the wire sizes in Table 2 should be used on projects that are designed using SI units.
(B) The number following the prefix indicates the nominal cross-sectional area of the wire in square
milimetres.
(C) For sizes other than those shown above, the Size Number shall be the number of square millimetres in the
nominal area of the wire cross section, prefixed by the MW.
(D) These sizes represent the most readily available sizes in the welded wire reinforcement industry. Other
wire sizes are available and many manufactures can produce them in 1 mm2 increments.
(E) The nominal diameter is based on the nominal area of the wire.
(A) The wire sizes in Table 3 should be used on projects that are
designed using inch-pound units; the wire sizes in Table 4 should be used on projects that are designed using SI units.
(B) The number following the prefix indicates the nominal cross-sectional area of the deformed wire in square
inches multiplied by 100.
(C) For sizes other than those shown above, the Size Number shall be the number of one hundredths of a square
inch in the nominal area of the deformed wire cross section, prefixed by the D.
(D) These sizes represent the most readily available sizes in the welded wire reinforcement industry. Other
wire sizes are available and many manufacturers can produce them in 0.0015 in.2 increments.
(E) The nominal diameter of a deformed wire is equivalent to the nominal diameter of a plain wire having the
same weight per foot as the deformed wire.
(F) The cross-sectional area is based on the weight of the wire. The area in square inches may be calculated by
dividing the weight in pounds by 0.2833 (weight of 1 in.3 of steel) or by dividing the weight per lineal foot of specimen in pounds by 3.4 (weight of steel 1 in. square and 1 foot
long).
(G) The minimum average height of the deformations shall be determined from measurements made on not less than
two typical deformations from each line of deformations on the wire. Measurements shall be made at the center of indentation or between two raised ribs as described in 7.2.4.7.
(H) Spacing of deformations shall not be greater than 0.285 in. nor less than 0.182 in. for all wire
sizes.
(I) See 7.2.4.3 for average number of deformations per unit
length.
(A) The wire sizes in Table 3 should be used on projects that are
designed using inch-pound units; the wire sizes in Table 4 should be used on projects that are designed using SI units.
(B) The number following the prefix indicates the nominal cross-sectional area of the deformed wire in square
millimetres.
(C) For sizes other than those shown above, the Size Number shall be the number of square millimetres in the
nominal area of the deformed wire cross section, prefixed by the MD.
(D) These sizes represent the most readily available sizes in the welded wire reinforcement industry. Other
wire sizes are available and many manufacturers can produce them in 1 mm2 increments.
(E) The nominal diameter of a deformed wire is equivalent to the nominal diameter of a plain wire having the
same weight per metre as the deformed wire.
(F) The cross-sectional area is based on the mass of the wire. The area in square millimetres may be calculated
by dividing the unit mass in kg/mm by 7.849 × 10-6 (mass of 1 mm3  of steel) or by dividing the unit mass in kg/m by 0.007849 (mass of steel 1 mm square and 1 m
long).
(G) The minimum average height of the deformations shall be determined from measurements made on not less than
two typical deformations from each line of deformations on the wire. Measurements shall be made at the center of indentation or between two raised ribs as described in 7.2.4.7.
(H) Spacing of deformations shall not be greater than 7.24 mm nor less than 4.62 mm for all wire sizes.
(I) See 7.2.4.3 for average number of deformations per unit
length.
Note 1: Welded wire for concrete reinforcement has historically been described by various terms: welded wire fabric, WWF, fabric, and mesh. The wire reinforcement industry has adopted the term welded wire reinforcement (WWR) as being more representative of the applications of the products being manufactured. Therefore, the term welded wire fabric has been replaced with the term welded wire reinforcement in this specification and in related specifications. 1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets (except in Table 2 and Table 4). The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values may result in nonconformance with the specification. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
