Steel C channels, also known as channel irons or simply channels, are versatile structural steel shapes with a C-shaped cross-section. Their unique profile provides excellent strength-to-weight ratio, making them a popular choice in various construction, manufacturing, and DIY applications. This comprehensive guide explores the properties, applications, sourcing, and considerations surrounding steel C channels, focusing on the American standard sizes and specifications.
Steel C Channel Size Chart:
Understanding the sizing of steel C channels is crucial for selecting the appropriate profile for your project. American steel C channels are typically designated by their nominal depth (height) in inches, followed by the weight per linear foot in pounds. For example, a "5x3x1/4" C channel indicates a channel with a nominal depth of 5 inches, a flange width of approximately 3 inches, and a thickness of 1/4 inch. Precise dimensions, including flange width, thickness, and web height, will vary slightly depending on the manufacturer and specific grade of steel. A comprehensive size chart would typically include:
* Nominal Depth: The overall height of the C channel.
* Flange Width: The width of the horizontal legs of the "C".
* Web Thickness: The thickness of the vertical portion of the "C".
* Flange Thickness: The thickness of the horizontal legs.
* Weight per Linear Foot: The weight of a one-foot section of the channel.
* Moment of Inertia (I): A measure of the channel's resistance to bending.
* Section Modulus (S): A measure of the channel's resistance to bending stress.
* Radius of Gyration (r): A measure of the channel's stiffness.
Note: Precise dimensions should always be obtained from the manufacturer's specifications or a relevant steel handbook. These dimensions are crucial for accurate calculations in structural design. Online resources and steel supplier catalogs frequently provide detailed size charts, often downloadable as PDFs (as requested in the prompt: "c channel size chart pdf"). These charts often include additional information like yield strength, ultimate tensile strength, and other relevant material properties.
Finding Steel C Channels: "Metal C Channel Near Me" and "Steel C Channel Near Me":
Locating steel C channels near your location is straightforward. Several avenues exist to find suppliers:
* Online Search Engines: Searching "metal C channel near me" or "steel C channel near me" on Google, Bing, or other search engines will yield a list of local metal suppliers, steel distributors, and even some larger hardware stores that stock steel channels.
* Online Steel Suppliers: Many online steel suppliers offer a wide range of steel products, including C channels, with options for delivery or pickup. These websites often feature detailed product information and online ordering capabilities.
* Local Metal Supply Yards: Visiting local metal supply yards or steel distributors is a good way to see the products in person, discuss your needs with knowledgeable staff, and potentially negotiate pricing. They can often provide advice on selecting the appropriate size and type of channel for your project.
* Construction Supply Stores: Larger home improvement centers and construction supply stores may carry smaller quantities of commonly used C channel sizes.
