Stainless Steel Channel Size Chart: UPN, UPE and American C Channel Dimensions & Weight Guide
Introduction
Stainless steel channels are widely used structural profiles in industrial fabrication, architectural structures and equipment manufacturing. Different standards such as European UPN, UPE and American C channels have different dimensions, flange designs and weight characteristics.
For engineers and buyers, selecting the correct stainless steel channel requires understanding profile dimensions, weight per meter, applicable standards and the differences between international channel systems.
This guide provides an overview of stainless steel channel sizes, including UPN, UPE and American standard C channels, helping buyers compare specifications before procurement.
Quick Answer: Stainless Steel Channel Size Guide
- UPN Channel:
European standard channel with tapered flanges, commonly used in structural applications. - UPE Channel:
European parallel flange channel designed for easier connections and efficient structural use. - American C Channel:
US standard channel profile with different dimensions and designation systems. - Channel weight depends on profile size, thickness and stainless steel density.
What Is Stainless Steel Channel?
A stainless steel channel is a structural metal profile with a U-shaped cross section. It consists of a web and two flanges, providing good load-bearing capability and easy connection options.
Compared with carbon steel channels, stainless steel channels provide improved corrosion resistance, making them suitable for applications where moisture, chemicals or hygiene requirements are important.
Main Parameters of Stainless Steel Channels
- Height (H)
- Width of flange (B)
- Web thickness (t)
- Flange thickness
- Weight per meter
- Length and tolerance
UPN vs UPE vs American C Channel
Although all three profiles are channel-shaped sections, their geometry and standard systems are different.
| Channel Type | Standard System | Main Characteristics |
|---|---|---|
| UPN Channel | European Standard | Tapered flanges, traditional structural channel design |
| UPE Channel | European Standard | Parallel flanges, easier fabrication and connection |
| American C Channel | US Standard | C-shaped profile with American designation system |
European Standard UPN Stainless Steel Channel Size Chart
UPN channels are commonly used in European structural applications. The following table shows commonly referenced sizes and approximate dimensions.
| Profile | Height H (mm) | Width B (mm) | Typical Weight (kg/m) |
|---|---|---|---|
| UPN 50 | 50 | 38 | Approx. 5.5 |
| UPN 65 | 65 | 42 | Approx. 7.1 |
| UPN 80 | 80 | 45 | Approx. 8.8 |
| UPN 100 | 100 | 50 | Approx. 10.6 |
Note: Actual weight may vary depending on manufacturing tolerance, stainless steel grade and production standard.
European Standard UPE Stainless Steel Channel Size Chart
UPE channels are European parallel flange channels designed for improved connection efficiency and easier fabrication compared with traditional UPN profiles.
Because of their parallel flange design, UPE channels are commonly selected for structural applications where connection accuracy and assembly efficiency are important.
| Profile | Height H (mm) | Width B (mm) | Typical Weight (kg/m) |
|---|---|---|---|
| UPE 80 | 80 | 46 | Approx. 7.9 |
| UPE 100 | 100 | 50 | Approx. 9.8 |
| UPE 120 | 120 | 55 | Approx. 12.1 |
| UPE 140 | 140 | 60 | Approx. 14.5 |
UPE dimensions may vary according to production standards and tolerance requirements. Buyers should confirm exact drawings and specifications before ordering.
American Standard Stainless Steel C Channel Size Chart
American C channels use a different designation system from European UPN and UPE channels. The profile name usually includes depth and weight per foot.
For example, C6×8.2 indicates an American channel approximately 6 inches deep with a nominal weight of 8.2 lb/ft.
| Profile | Depth (inch) | Weight (lb/ft) | Typical Application |
|---|---|---|---|
| C3×4.1 | 3 | 4.1 | Light structural frames |
| C5×6.7 | 5 | 6.7 | Equipment supports |
| C6×8.2 | 6 | 8.2 | Industrial structures |
| C8×11.5 | 8 | 11.5 | Heavy structural applications |
American channel dimensions should always be checked according to the required ASTM or AISC standard because flange width and thickness vary between profiles.
How to Calculate Stainless Steel Channel Weight
The weight of a stainless steel channel depends on its cross-sectional area, material density and profile dimensions.
Basic Weight Formula
Weight (kg/m) = Cross-sectional Area (cm²) × Density (g/cm³) × 0.1
For stainless steel, a commonly used density value is approximately 7.93 g/cm³. Actual weight may vary slightly due to dimensional tolerance and manufacturing conditions.
| Factor | Influence on Weight |
|---|---|
| Channel Height | Larger height generally increases weight per meter |
| Flange Width | Wider flange increases material volume |
| Thickness | Greater thickness significantly increases weight |
Stainless Steel Channel Tolerance and Procurement Considerations
When purchasing stainless steel channels, dimensions alone are not sufficient. Buyers should confirm manufacturing standards, tolerances, surface condition and material requirements.
- Channel standard: UPN, UPE, ASTM or customer drawing
- Stainless steel grade: 304, 316 or other grades
- Length tolerance and straightness requirements
- Surface finish requirements
- Material certificate and inspection documents
- Cutting and fabrication requirements
For structural projects, dimensional accuracy and mechanical properties should be confirmed according to the applicable standard before production.
Applications of Stainless Steel Channels
Stainless steel channels are selected for applications where structural support, corrosion resistance and long service life are required. Compared with carbon steel channels, stainless steel channels provide better resistance against moisture, chemicals and harsh environments.
| Industry | Typical Applications |
|---|---|
| Architecture and Construction | Structural frames, supports, decorative structures and building components |
| Food Processing | Equipment frames, hygienic structures and processing systems |
| Chemical Industry | Corrosion-resistant supports and equipment structures |
| Marine Applications | Structures exposed to seawater and humid environments |
| Industrial Equipment | Machine frames, brackets and fabricated components |
Common Standards for Stainless Steel Channels
Stainless steel channels can be supplied according to different international standards depending on the profile type, application and customer requirements.
| Standard | Description | Application |
|---|---|---|
| EN 10279 | Dimensions, shape and tolerances of hot rolled steel channels | European UPN and UPE channel profiles |
| ASTM A276 | Stainless steel bars and shapes requirements | Stainless steel structural shapes |
| ASTM A484 | General requirements for stainless steel products | Dimensions, testing and quality requirements |
| Customer Drawing | Customized dimensions and profile requirements | Special stainless steel channel fabrication |
