Multiple Choice

How many total SFRM thickness measurements are taken on a joist?

Measuring SFRM thickness across a joist is done with multiple checks along its length and on the different faces to ensure uniform coverage and that the specified thickness is met. Seven measurement locations are typically taken on each side of the joist, giving a total of fourteen readings per joist. This sampling captures variations that can occur along the length and between faces (top and bottom surfaces, or opposite sides of the joist), helping verify both the average thickness and the minimum thickness meet the required tolerance. Fewer measurements could miss thin spots, while this level of sampling provides a reliable representation without unnecessary excess.
