What is 3003 Aluminum Tread Plate?
A versatile material combining aluminum's lightweight properties with anti-slip functionality and decorative appeal for industrial and commercial applications.
Premium Quality Manufacturing
High-purity aluminum ingots processed with advanced rolling technology for consistent quality and performance.
Technical Specifications
- Base Material 3003 Aluminum Alloy
- Composition 96.8-99% Al + 1-1.5% Mn
- Core Temper H22 (1/4 Hard)
- Tensile Strength ≥22,000 psi
- Standards ASTM B209, QQ-A-250/2
Why 20% Stronger? The 1-1.5% manganese content enhances strength compared to 1100 series pure aluminum, while maintaining excellent corrosion resistance and workability.

Classification Guide
Select the perfect 3003 aluminum tread plate based on temper, pattern, thickness, and surface finish.
Classification by Temper
Temper determines hardness and formability. Select based on your project's load requirements.
3003 H22
1/4 Hard • Strain-hardened + Partially Annealed
Excellent formability with balanced strength.
Best For:
Truck steps, stair treads, decorative wall panels
3003 H14
1/2 Hard • Strain-hardened + Partially Annealed
Good formability with increased hardness.
Best For:
Garage floors, light-duty shelf steps
3003 O-Temper
Soft • Fully Annealed
Maximum formability for complex shapes.
Best For:
RV curved floors, irregular signs
Classification by Pattern Type
Pattern determines anti-slip performance and visual effect. Select based on safety requirements.
Diamond Plate
10mm×10mm spacing
Toolboxes, elevator floors, decorative
5-Bar Checker
5 parallel ribs
Workshop walkways, loading ramps
3-Bar Checker
3 wide ribs, 15mm spacing
Stair treads, wall decorative strips
FTQ Fire-Resistant
Diamond + serrations
Fire trucks, ambulances, cold storage
Pro Tips: For food processing plants, use "seamless diamond pattern" (small gaps, easy cleaning, FDA compliant). For offshore platforms, choose "anodized + 5-Bar" for 30% better salt spray resistance.
Classification by Thickness
Thickness determines load-bearing capacity. Note the gauge conversion for Western customers.
| Thickness (inches) | Gauge | Weight (lbs/sq.ft) | Load Capacity | Typical Applications |
|---|---|---|---|---|
| 0.063" (1/16) | 14 | 1.0 | ≤50 kg/㎡ | Decorative panels, light toolboxes |
| 0.100" | 10 | 1.6 | ≤100 kg/㎡ | Truck running boards |
| 0.125" (1/8) | 8 | 1.9 | ≤150 kg/㎡ | Stair treads, garage floors |
| 0.250" (1/4) | N/A | 3.7 | ≤300 kg/㎡ | Trailer floors, tanker steps |
Classification by Surface Finish
Surface finish determines corrosion resistance and visual style. Select based on environment.
Brite (Bright)
Polished, mirror effect
Bar walls, food truck exteriors
Mill Finish
As-rolled, no polishing
Trench covers, industrial structures
Anodized
10-15μm oxide film
Park boardwalks, exterior wall panels
Powder Coated
Electrostatic, RAL colors
Brand logos, exhibition hall floors

3003 vs. 6061 Aluminum Tread Plate
Choose the right alloy for your specific requirements.
| Dimension | 3003 Aluminum | 6061-T6 Aluminum | Recommendation |
|---|---|---|---|
| Composition | Al 98.7% + Mn 1-1.5% | Al 97.9% + Mg 1-1.6% + Si 0.4-0.8% | - |
| Tensile Strength | 22,000 psi | 42,000 psi | 3003 for ≤300kg/㎡; 6061 for >300kg/㎡ |
| Weldability | Excellent | Good (post-weld heat treatment) | 3003 for welded structures |
| Formability | Excellent | Moderate | 3003 for complex shapes |
| Corrosion Resistance | Excellent (no treatment) | Good (anodization needed) | 3003 for low-maintenance outdoor |
| Cost | Low (10-15% cheaper) | High | 3003 for general; 6061 for high-strength |
Pro Tip: 3003-H22 + anodization is the most cost-effective choice for projects requiring medium strength, welding capability, and outdoor durability.
