Converts rebar into a wire size and
spacing at a specified grade of steel.
Long wire variable spacing.
Cross wire variable spacing.
Minimum long wire spacing is 2 inches.
Typical wire spacing is in even increments
(2, 4, 6, 8...), but odd wire spacing can be produce.
Minimum cross wire spacing is 2 inches.

(2, 4, 6, 8...), but odd wire spacing can be produce.
Wire sizes are entered in hundred square inches
(#3 bar = 0.11 square inches and would be entered
as 11.0 hundred square inches). Wire Sizes are not
limited to standard sizes like conventional rebar.
Wire sizes range from 1.4 to 45 hundred square
inches and can be produced in increments as small
as a hundredth of a square inch. Wire sizes need to
be at least 40% of the cross wire size to guarantee
an adequate weld.

The sheet width is measured from the outermost
long wire to outermost long wire, or the overall
width of the sheet minus any side overhangs.
Sheets widths are typically designed to about 8 feet
for ease of shipment. Ivy Steel & Wire can produce
sheets up to 17 feet wide. Designers need to
understand the relationship between long wire
spacing and sheet width. The sheet width is the sum
of all the long wire spacings and therefore needs to
be evenly divisible by the long wire spacing.
Side overhangs range from a flush cut to whatever
the designer wants. The designer should consider
the transportability of the sheet when designing
long side overhangs. Typically long overhangs are
designed into sheets to accommodated finger laps.
Side overhangs range from a flush cut to whatever
the designer wants. The designer should consider
the transportability of the sheet when designing
long side overhangs. Typically long overhangs are
designed into sheets to accommodated finger laps.
The overall width is the combination of the width
(line wire to line wire) plus the two side overhangs.
Sheet lengths can be produced in any length up to
45 feet, and is measured from the outermost cross
wire to outermost cross wire, or the overall length
of the sheet minus any end overhangs. Designers
need to understand the relationship between cross
wire spacing and sheet length. The sheet length is
the sum of all the cross wire spacings and therefore
needs to be evenly divisible by the cross wire spacing.
For example a sheet measuring 9 feet in length is
evenly divisible by a 6 inch cross wire spacing but
not by an 8 inch spacing. The designer would either
adjust the end overhangs or the sheet length to
compensate for the 8 inch spacing.
End overhangs range from a flush cut to whatever
the designer wants. The designer should consider
the transportability of the sheet when designing
long end overhangs. Typically long overhangs are
designed into sheets to accommodated finger laps.

The overall length is the combination of the length
(cross wire to cross wire) plus the two end overhangs.
The square feet of the sheet is the product
of the overall length and the overall width.
The number of long wires in the sheet.
This number must be a whole number.
The number of cross wires in the sheet.
This number must be a whole number.
The sheet weight is the sum of the individual
line wires and cross wire weights.
D indicates deformations on the wire similar to conventional rebar.

welded wire reinforcement will be used.

Specified reinforcement yield strength (psi).
Coating factor -
Epoxy-coated bars or wires with cover less than 3db,
or clear spacing less than 6db is 1.5,
all other epoxy-coated bars or wire is 1.2,
uncoated reinforcement is 1.0.
Lightweight concrete factor –
Lightweight concrete is 1.3
and normal weight concrete is 1.0.
Concrete cover factor (in) –
Use the smaller of either the distance from the
center of the bar or wire to the nearest concrete
surface or one-half the center-to-center spacing
of the bars or wires being developed.
Reinforcement size factor –
#6 and smaller bars & deformed wire use 0.8 and
for #7 and larger bars use 1.0.
Reinforcement location factor -
Horizontal reinforcement so placed that more
than 12 inches of concrete is cast in the member
below the development length or splice (Wall)
use 1.3. All other reinforcement 1.0.
Number of bars or wires being developed along
the plane of splitting.
ACI 318 Code does not permit a
finger splice with smooth wire.
This is the length of a finger splice with deformed
wire. The splice is located on the left or right side
of the sheet. Length of the finger splice is measured
between the ends of each sheet.
This is the length of a cross splice or overlap splice
with smooth wire. The splice is located on the left
or right side of the sheet. Length of the splice is
measured between the ends of each sheet.
This is the length of a cross splice or overlap splice
with deformed wire. The splice is located on the
left or right side of the sheet. Length of the splice
is measured between the ends of each sheet.
Lap calculations are performed in accordance with
the ACI 318 Building Code. There are three possible
lap conditions: a smooth wire cross lap, a deformed
wire cross lap, and a deformed wire finger lap. The
lap values are displayed in a matrix providing the
designer with an easy to use tool in determining the
right splices length. Just enter the appropriate splice
length in the box.

ACI 318 Code does not permit a

This is the length of a finger splice with deformed
wire. The splice is located on the top or bottom end
of the sheet. Lenght of the finger splice is measured
between the ends of each sheet.
