Wire-fabric lath is fabricated from which material?

Wire-fabric lath is fabricated from which material?

• A. Copper-bearing steel sheets
• B. Aluminum sheets
• C. Stainless steel mesh
• D. Plastic-coated wire

Answer: (A)

Wire-fabric lath uses a durable metal that can be woven into a mesh and provide a good key for plaster. Copper-bearing steel offers the right balance of strength, ductility, and corrosion resistance, and the copper content helps the plaster adhere and resist moisture-related deterioration over time. That combination makes copper-bearing steel the standard material for this type of lath. Other materials listed don’t fit the typical use: aluminum is not as strong or durable for a plaster key, stainless steel mesh exists but is not the common material for standard wire-fabric lath, and plastic-coated wire isn’t the fabric form commonly used for lath in plastering.
