How to Use the Wire Mesh Calculator
Welded wire reinforcement (WWR) is a prefabricated grid of steel wires welded at each intersection. It is widely used in residential slabs, driveways, and light industrial floors where uniform, consistent reinforcement is needed without the labor of tying individual rebar.
Enter your slab area, select a mesh specification and sheet size, then add your required lap allowance (15% is typical). The calculator returns the number of sheets to order along with the total material weight for planning deliveries.
Common Mesh Designations
- W1.4/W1.4 (D6@150): light slabs, sidewalks
- W2.5/W2.5 (D8@150): standard residential floors
- W3.9/W3.9 (D10@200): heavier industrial floors
Frequently Asked Questions
ACI 318 requires a minimum one-mesh-spacing lap, not less than 6 inches. A 15% allowance works for most regular rectangular slabs; use 20% if the layout has many cuts.
Standard flatbed trucks typically carry 50–100 sheets depending on sheet size and weight. Confirm with your supplier, as crane offload may be needed for large-quantity deliveries.
