Final answer:
The most common welded-wire fabric used in residential construction has wires spaced 6 inches apart, known as 6x6 W1.4/W1.4 welded-wire reinforcement.
Step-by-step explanation:
The most common welded-wire fabric used on a residential job site has wires spaced 6 inches apart in two directions. This type of material is referred to as 6x6 W1.4/W1.4 welded-wire reinforcement (WWF or WWM). Welded-wire fabric, or WWF, is a prefabricated grid of steel wires used to reinforce concrete.
The designations such as 6x6 W1.4/W1.4 indicate the spacing of the wires in the mesh (6 inches both ways) and the gauge or diameter of the wire (W1.4 referring to the wire size).
