Wire Sizes - The size of
the wire is given as a W number or a D number. W denotes a plain
wire and D means deformed. The number that follows the letter is
the area of the wire in hundredths of a square inch. For instance,
a W10.2 wire would be a plain wire with a cross sectional area of
0.102 square inches while a D7.4 would indicate a deformed wire
with a cross sectional area of 0.074 square inches.
Style
- Spacings and sizes of wire in standard welded wire fabric are
identified by "style". A typical designation is 6 x 12 - W16 x W8.
This denotes a welded wire fabric in which: Spacing of
longitudinal wires = 6". Spacing of transverse wires = 12". Size
of longitudinal wires = W16 (0.16 sq. in.) Size of transverse wire
= W8 (0.08 sq. in.)
Standard Stocking Sizes are 6' Wide x 150' Long, with a 6" x 6", 10 Ga. Mesh wire.

Standard Reinforcing Bars
Rebar is consumed in a wide variety of end uses, divided into roughly equal
portions between private sector applications, such as construction of
commercial, industrial and multiple unit residential buildings, utility
construction, agricultural uses and various maintenance and repair
applications and public works projects, such as construction of highways
and bridges, public buildings and water treatment facilities.
Rebar comes in a variety of lengths up to 60 Feet.
20 Ft. lengths are a standard stock size . Other sizes are special order.

Epoxy-
Coated Reinforcement Bar 
What is Epoxy-Coated
Reinforcement?
Fusion-bonded epoxy
coating is applied to black reinforcing bar by epoxy coating
plants. The color of the epoxy is typically green but can appear
in other colors depending on the coater.
In the last 25 years,
the cost of maintaining, rehabilitating and reconstructing
corrosion-damaged reinforced concrete structures has rapidly
escalated, necessitating more cost-effective corrosion protection
systems. With this need, epoxy-coated reinforcement has gained
widespread acceptance as a means to extend the service life of
bridges, parking garages and other reinforced concrete structures
susceptible to corrosion.
