What is the weight requirement for the expanded metal lath used for mechanical bonding?

• A. 1.5 lbs per yd².
• B. 2 lbs per yd².
• C. 1.7 lbs per yd².
• D. 1.2 lbs per yd².

Answer: (C)

The weight requirement for expanded metal lath used for mechanical bonding is specified at 1.7 pounds per square yard. This is crucial because it ensures that the lath provides sufficient structural integrity and durability when applied in various construction scenarios, particularly in plastering and stucco applications. A weight of 1.7 lbs per yd² strikes a balance between being robust enough to support the plaster while still allowing for flexibility and ease of installation. Adhering to this specific weight ensures compliance with building standards and codes, which are critical for long-lasting, safe structural performance.
