In a wall assembly a main channel, also known as a U-Channel is fitted to the ceiling and the floor in order to effectively hold the studs in place. Drywall furring channel are commonly clipped with metal furring channel clips or wire-tied perpendicular to the main channel at appropriate intervals for screw-attaching drywall. Furring channel can also be attached directly to the underside of bar joists. The furring are installed perpendicular to the joists and wire-tied at appropriate intervals. Wire ties are required for fire-rated and multilayer assemblies.
Steel Main Channels are a Hot Rolled product. When looking at a cross section, it has a horizontal top with a vertical web and bottom flanges. It comes in a wide range of sizes and thicknesses. The shape of this type of product provides a great amount of structural strength, making it an ideal product for making bracings and frames. Typically, it is used in the manufacturing of machinery, enclosures, vehicles and in the construction of buildings for structural support. The Structural Channel, also known as a C-Channel is distinguished from I-beam or H-beam or W-beam, which has flanges on both sides of the web. The only exception to the above method in channel measurement would be the similar Main or U-Channel, which are measured by the depth, then the flange height, and lastly the web thickness.
Some salient features of Steelco main channels are:
- Commonly used in noncombustible fire proof assemblies
- Rigid, durable and strong framework for a high-quality finish
- Furring are designed with convenience in mind thus the channels clip easily snap into place for a faster assembly
