U Channel Steel Dimensions & Steel U Channel Sizes Guide
U channel steel is a widely used structural steel product in construction, infrastructure, and industrial fabrication. With its U-shaped cross-section, it provides excellent load-bearing capacity, easy installation, and high versatility. Choosing the correct u channel steel dimensions is essential for structural safety, durability, and cost efficiency.
Shineyond Group is a professional steel manufacturer and exporter, supplying high-quality U channel steel in standard and customized sizes for global construction projects, especially in infrastructure and building applications.
What Is U Channel Steel?
U channel steel, also known as steel U channel, features a U-shaped cross-section with two parallel flanges and a flat web. It is typically produced by hot rolling or cold forming and can be supplied as carbon steel or galvanized steel for enhanced corrosion resistance.
At Shineyond Group, U channel steel products are manufactured under strict quality control, ensuring accurate dimensions, stable mechanical properties, and consistent performance.
What Are the Standard Steel U Channel Sizes?
Steel U channel sizes are defined by three key dimensions:
Web Height (H) – the overall depth of the channel
Flange Width (B) – the width of the side flanges
Thickness (T) – the thickness of the web and flanges
Shineyond Group supplies steel U channels in accordance with common international standards such as ASTM, EN, JIS, and GB, meeting the needs of different markets.

| U200 | 200 | 75 | 8.0 | 29.80 |
Note: Actual dimensions and weights may vary slightly depending on production standards and tolerances.
Galvanized Steel U Channel Sizes
For outdoor, coastal, or humid environments, galvanized steel U channels are highly recommended. These products follow the same u channel steel dimensions as carbon steel but feature a zinc coating for long-term corrosion protection.
Shineyond Group offers hot-dip galvanized U channel steel in popular sizes such as:
U50 × 25 × 3.0 mm
U80 × 40 × 4.0 mm
U100 × 50 × 5.0 mm
U120 × 55 × 5.5 mm
U160 × 65 × 6.5 mm
Custom zinc coating thickness and length can also be provided.
Applications of Steel U Channel Sizes
U Channel Size Range | Typical Applications |
Small (U50–U80) | Light frames, brackets, equipment supports |
Medium (U100–U140) | Building frames, wall supports, machinery bases |
Large (U160–U200) | Bridges, platforms, heavy steel structures |
Shineyond Group U channel steel products are widely used in residential buildings, warehouses, factories, solar structures, and infrastructure projects.
How to Choose the Right U Channel Steel Dimensions?
When selecting steel u channel sizes, consider the following:
✅ Load Requirements – Larger channels support heavier loads
✅ Span Length – Longer spans require deeper channels
✅ Environment – Choose galvanized U channels for corrosion resistance
✅ Installation Method – Welding or bolting affects thickness selection
✅ Project Standards – Always comply with engineering codes
Pro Tip: For most construction projects, U100 to U140 U channel steel offers an excellent balance between strength and cost.
