A "CH" stud, also known as a "C-H" stud, is a type of shaft wall stud used in construction. These studs are specifically designed for shaft wall assemblies, which are fire-rated walls used in multi-story buildings, particularly around elevator shafts and stairwells.
Key Characteristics of CH Studs:
Here's a breakdown of what makes CH studs unique, based on the reference information:
- Material: CH studs are manufactured from hot-dipped galvanized steel with a standard G40 coating, which provides corrosion resistance and durability.
- Geometric Properties: The "C-H" shape is characterized by a "C" section with a unique flange structure:
- Web Depths: They are available in 2-1/2", 4", and 6" web depths. The web is the vertical part of the stud.
- Flange Widths: Each stud has two flanges, one shorter (1-3/8") and one longer (1-1/2"). Flanges are the horizontal parts of the stud.
Table of CH Stud Dimensions:
| Property | Size(s) |
|---|---|
| Web Depth | 2-1/2", 4", 6" |
| Short Flange Width | 1-3/8" |
| Long Flange Width | 1-1/2" |
| Steel Coating | Hot-dipped galvanized steel with G40 coating |
Usage and Applications:
- Shaft Walls: As the name suggests, CH studs are primarily used in the construction of shaft walls. These walls are essential for fire safety.
- Fire-Rated Construction: Their design helps in creating robust and fire-resistant barriers within a building, containing fire and allowing for safe evacuation.
Practical Insights:
- Ease of Installation: The design of CH studs makes them relatively easy to install and work with on construction sites.
- Strength and Stability: The steel construction gives these studs the strength and rigidity required for demanding building applications.
- Compliance: CH studs must comply with relevant building codes and standards.
