Stainless Steel Channels‌ | U-Shaped Structural Support

Stainless Steel Channels Product Details

​Specifications, Hardness, Sizes, Properties & Manufacturing Process

​Key Performance Properties

​Tensile Strength

Stainless steel u channel grades like 304 and 316L exhibit tensile strengths of ​**≥520 MPa** and ​**≥485 MPa**, respectively, ensuring durability in load-bearing applications such as balustrades and industrial frameworks. Duplex 2205 channels combine austenitic and ferritic properties, achieving ​**≥620 MPa tensile strength**, ideal for corrosive environments like offshore platforms.

​Bend Strength

Cold-rolled ​stainless steel strut channel products demonstrate superior bend resistance due to work hardening. For example, hot-rolled 304 channels achieve ​**≥205 MPa yield strength**, while cold-drawn variants reach ​**≥350 MPa**, suitable for seismic-resistant construction.

​Identification & Marking

Each ​stainless steel unistrut channel is laser-etched with:

• ​Material Grade (e.g., SUS304)
• ​Standard Code (e.g., ASTM A554)
• ​Heat Number (traceability)
• ​Dimensions (H × B × Thickness)
  
  Custom markings, such as client logos or QR codes, are available for OEM orders.

​Weight Calculation Formula

Weight (kg/m) = $\text{Cross-Sectional Area (mm²)}\times 0.00785\times \text{Length (m)}$
Example: For a 50mm × 30mm × 3mm ​stainless steel strut channel:
$(50\times 3+30\times 3)\times 0.00785=1.88\text{kg/m}$.

​Why Stainless Steel Channels May Rust?

Despite corrosion resistance, rust can occur under specific conditions:

1. ​Chloride Exposure: Coastal or de-icing salt environments degrade the chromium oxide layer, causing pitting.
2. ​Iron Contamination: Residual iron particles from cutting tools create localized galvanic corrosion.
3. ​Low Chromium Content: Grades with <10.5% chromium (e.g., 430) lack stable passive layers.
4. ​High-Temperature Oxidation: Prolonged exposure to >400°C oxidizes surfaces, especially in 304-grade channels.

Preventive Measures:

• Select ​stainless steel unistrut channel with 316L (2.5% Mo) for marine or chemical exposure.
• Passivate surfaces post-fabrication to restore chromium oxide layers.
• Use non-abrasive cleaning agents (pH 6–8) to avoid scratching.
