PrimeWall® Cold-Rolled Channel

PrimeWall Cold-Rolled Channel

PrimeWall® Cold-Rolled Channel is used to provide support for studs thereby preventing torsional rotation in interior partition walls. It is manufactured only from mill-certified steel, providing additional option to other methods of bridging such as BridgeBar® for those who prefer a choice. Cold-Rolled Channel should be attached at each stud with a clip such as BridgeClip® or PrimeWall Angle.

Product Information
TSN_PrimeWall_Cold-Rolled_Channel_Nomenclature_no_example.png PrimeWall_Cold-Rolled_Channel_Shape_Key_Horizonal.png

PrimeWall® Cold-Rolled Channel is designated by overall depth followed by channel type, then leg lenth and material thickness:

Depth (decimal(in) x 100) + U (Channel) + Leg (decimal(in) x 100) + mils

Example: 1.5” depth, 0.5” leg, 16ga
Designate: 150U050-54, 33ksi

PrimeWall Cold-Rolled Channels are available in 0.75" and 1.5” depths, 0.5” leg, and 54mil (16ga).

Important Notes
1. Section properties and capacities are calculated in accordance with AISI-NASPEC 2007.
2. Tabulated gross properties are based on the full, unreduced cross section of the cold-rolled channel.
3. For deflection calculations, use the effective moment of inertia (Ix). This Ix is calculated at a stress which results in a section modulus such that the stress times the section modulus at that stress is equal to the allowable moment. AISI S100-07 Procedure I for serviceability determination has been used.

Important Notes
1. Allowable ceiling spans are based on effective properties.
2. Multiple span indicates two or more equal spans with channel continuous over center support.
3. Bearing length is equal to 0.75 inches.
4. Table values are based on the compression flanged laterally unsupported.
