Welded wire fabric is designated by two numbers and two letter-number combinations. An example is 6 by 8—W8.0 by W4.0. The first number gives the spacing in inches of the longitudinal wire s , the second g i v es the spacing of the tra n s ve r s e w i re s . The first letter-number com-bination gives the type and size of
Exposed rebar, pipe, threaded rod, shebolts, etc., create potential hazards which can result in employee injury and lost time.
Welded wire reinforcement (WWR) is a prefabricated reinforcement consisting of high strength, cold-drawn or cold-rolled wire welded together in square or rectangular grids. Each wire intersection is electrically resistance-welded by a continuous automatic welding machine.
Tables are included to compare steel areas for reinforcement with a minimum yield strength of 60,000 psi and three higher minimum yield strengths, i.e., 70,000, 75,000 and 80,000 psi, for WWR. Tables 3-6 consider steel wire sizes ranging from W1.4 (1/8”φ to W or D 45 (3/4”φ).

2013年3月11日 · 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.
welded wire reinforcement industry. This table should be used on projects designed using inch-pound units. Areas of wire should be checked with the most efficient and readily available material from producers. Other wire sizes are available and many manufacturers can produce them in 2-mm (0.0015-in2) increments. 2.

2024年4月15日 · Welded-wire fabric is an orthogonal grid made with two kinds of cold-drawn wire: plain or deformed. The wires can be spaced in each direction of the grid as desired, but for buildings, usually at 12 in maximum. Sizes of wires available in each type, with standard and former designations, are shown in Table 9.6.

The primary purpose of welded wire reinforcement in slabs is to control cracking and crack widths in both directions. Welded wire reinforcement keeps the cracked sections of a slab closely knit together so that the slab will act as a unit. WWR Helps Aggregate Interlock . When a slab cracks, the faces within the crack are jagged.
This large mechanical bender at a wire mesh plant is capable of bending 1⁄ 2-inch-diameter wire at 4 inches on center in sheets up to 30 feet long. Movable mandrels adjustable to various spacings permit the bending of many different shapes with precision. Photo: Ivy Steel & Wire Company U.S. AND CANADIAN SPECIFICATIONS FOR WELDED WIRE FABRIC ...
