Study Notes

Use of Metal Stud Soffits

Metal stud soffits are lightweight structures, typically made of galvanized steel, used in various constructions (commercial, institutional, residential).
They are often used in remodeling existing buildings.
Soffits provide a nonflammable covering for ceilings, walls, and air returns.
Soffits can be designed with various depths and widths.

Design of Soffits

Metal stud or track, 1 5/8-inch wide, is typically the framing for soffits.
This type of soffit might be used to enclose a heat duct.
Eye brow walls and curtain walls are similar designs.

Method of Constructing a Metal Stud Soffit

To frame a soffit, the drywall mechanic needs two measurements: depth of soffit and width of soffit.
Measure the depth from the ceiling or up from the floor, after checking the building plans.
A line is snapped.
A metal track is installed horizontally and attached at the point of each vertical framing member.
Ensure the metal track is level. This horizontal member is called the wall runner.
To get the intervals between the points of measurement for the face and width, the soffit should be consulted.
A piece of metal track is applied as the soffit.
This piece of wall board should be attached to the ceiling runner.
The vertical and horizontal angles in a steel soffit assembly should be straight, level, and plumb.
The easiest method for accomplishing this is with the use of tightly drawn strings. Accuracy in measuring is essential so as to allow the finish material that goes on the soffit to most important.
The string should make allowance for the finish material to contact with the string and the vertical.
The drywall mechanic should next screw through the face of the wall runner and into a metal stud.
Rip the board and into the metal stud, forming the bottom of the soffit.
Corner bead should be applied to the external corner formed.
For large soffits, supporting studs are needed on 24-inch centers.
1 5/8-inch stud carries up to an 8-foot span; a 2 1/2-inch stud carries up to a 6-foot span; and a 3 5/8-inch stud carries up to a foot span.
