What additional percentage is included for overlaps when measuring welded wire mesh?
5%
10%
15%
20%
The correct answer is: 10%
When measuring welded wire mesh, it is important to account for overlaps that occur during installation. Installing welded wire mesh typically requires overlapping adjacent sheets to ensure structural integrity and effective load distribution. The additional percentage added to the total measured area accounts for these overlaps and variations in installation. The commonly accepted figure for overlaps in estimating welded wire mesh is 10%. This percentage covers the necessary additional material that needs to be included due to overlaps that occur when the sheets do not perfectly align or when they need to be secured. By including this additional percentage in the estimation, one ensures that enough material is provided for the entire project while avoiding shortages that could lead to delays or increased costs. Using this 10% standard ensures a more accurate estimation of the required quantities and helps maintain the project's efficiency and effectiveness.
