What type of steel studs can replace metal lath for creating a break in SFRM application?

In the context of spray-applied fire-resistive materials (SFRM) application, the choice of steel studs is crucial for ensuring proper structural integrity and fire resistance. The use of 12-gauge steel studs effectively provides the necessary strength and stability needed for the construction framework when replacing metal lath.

12-gauge steel studs have a thickness that offers excellent support for the application of SFRM, which is important for maintaining the fire-resistive properties and securing the material onto the structural elements. This gauge provides a strong backbone, minimizing the risk of deformation or damage during the spraying process and ensuring that the SFRM adheres appropriately.

In comparison, other options such as 14-gauge, 16-gauge, or 18-gauge studs offer less structural strength compared to the 12-gauge option. These thinner gauges may not provide the same level of support and stability, which could compromise the effectiveness of the fireproofing application. The 12-gauge studs strike a balance between weight considerations and structural performance, making them the ideal choice for replacing metal lath in SFRM applications.
