Steel channels are a fundamental component in construction, fabrication, and industrial projects, offering strength, versatility, and ease of installation. One commonly used size is the C3 x 4.1 steel channel, a compact yet reliable structural shape suited for light to medium-duty applications. Understanding its dimensions, characteristics, and common uses can help engineers, fabricators, and builders choose the right material for their projects. Bobco Metals supplies high-quality steel channels, including C3 x 4.1, to meet a wide range of industry needs.
What Does C3 x 4.1 Mean?
The designation C3 x 4.1 follows standard structural steel naming conventions.
-
The “C” indicates a steel channel, which has a “C”-shaped cross-section with a web and two flanges on one side.
-
The “3” represents the nominal depth of the channel in inches.
-
The “4.1” refers to the weight in pounds per linear foot.
This naming system allows professionals to quickly understand the size and relative strength of the channel without needing to review detailed drawings every time.
C3 x 4.1 Channel Dimensions (Overview)
While exact dimensions may vary slightly depending on the mill and specification, a typical C3 x 4.1 steel channel generally includes:
-
Depth: Approximately 3 inches
-
Weight: 4.1 pounds per foot
-
Flange Width: Around 1.4 inches
-
Web Thickness: Approximately 0.17 inches
-
Flange Thickness: Approximately 0.17 inches
These compact dimensions make the C3 x 4.1 channel ideal for projects where space is limited but structural integrity is still required. Bobco Metals can provide exact dimensional data and specifications upon request to ensure compliance with project requirements.
Material Grades and Specifications
C3 x 4.1 channels are commonly produced in carbon steel grades such as ASTM A36, though other grades may be available depending on application needs. ASTM A36 steel is widely used due to its excellent weldability, machinability, and overall strength, making it suitable for structural and fabrication work.
Bobco Metals offers steel channels that meet industry standards, helping customers maintain quality and consistency across their projects.
Common Applications of C3 x 4.1 Steel Channel
Because of its manageable size and strength, the C3 x 4.1 channel is used in a variety of industries and applications, including:
-
Light structural framing in commercial and residential construction
-
Equipment supports and bracing
-
Industrial shelving and racking systems
-
Trailer frames and vehicle components
-
Fabrication projects such as guards, frames, and reinforcement members
Its lighter weight makes handling and installation easier, which can reduce labor costs while still delivering dependable performance.
Advantages of Using C3 x 4.1 Channel
One of the key benefits of the C3 x 4.1 channel is its balance between strength and efficiency. It provides sufficient load-bearing capacity for many light-duty applications without the added weight or cost of larger structural members. Additionally, steel channels are easy to cut, drill, and weld, making them a favorite among fabricators.
Bobco Metals ensures consistent quality and reliable supply, allowing customers to focus on project execution rather than material concerns.
Fabrication and Installation Considerations
When working with C3 x 4.1 steel channel, it is important to consider factors such as load requirements, span length, and environmental exposure. Proper surface treatment, such as priming or galvanizing, may be recommended for outdoor or corrosive environments.
Bobco Metals can assist customers in selecting the right steel channel and provide guidance on fabrication compatibility and finishing options.
