A stainless steel checker plate, also known as tread plate or chequered plate, is a flat sheet of stainless steel with a raised diamond or linear pattern on one side. This design not only adds aesthetic appeal but provides excellent slip resistance, making it ideal for industrial flooring, stairs, ramps, and loading docks.
Checker plates are commonly produced using hot rolling or cold rolling methods, depending on the thickness and application. Available in 304, 316, 430, and other stainless steel grades, they are widely favored for their corrosion resistance, durability, and hygiene standards.
1. Mechanical & Chemical Properties
The performance of a checker plate is largely dictated by its chemical composition and mechanical strength. Below is a breakdown of typical properties:
| Property | 304 Grade | 316 Grade | 430 Grade |
|---|---|---|---|
| Tensile Strength (MPa) | 520 – 750 | 515 – 760 | 450 – 600 |
| Yield Strength (MPa) | ≥205 | ≥205 | ≥195 |
| Elongation (%) | ≥40 | ≥40 | ≥22 |
| Hardness (HB) | ≤201 | ≤217 | ≤183 |
| Chromium (%) | 18.0 – 20.0 | 16.0 – 18.0 | 16.0 – 18.0 |
| Nickel (%) | 8.0 – 10.5 | 10.0 – 14.0 | 0.0 – 0.75 |
| Molybdenum (%) | 0.0 | 2.0 – 3.0 | 0.0 |

2. Surface Patterns and Finishes
Common patterns include:
-
Diamond/5-Bar Tread Pattern: Highly slip-resistant.
-
Single Bar Checker: Ideal for lightweight anti-slip use.
-
Circular/Teardrop Patterns: Preferred in decorative applications.
Available surface finishes:
-
2B Finish: Smooth, reflective, mill finish for general industrial use.
-
No. 1 Finish: Rough, hot-rolled finish used in structural applications.
-
BA Finish: Bright annealed for aesthetic applications.
3. Stainless Steel Checker Plate Grades Comparison
Understanding how different grades compare is crucial for optimal selection.
| Grade | Corrosion Resistance | Cost | Machinability | Common Use |
|---|---|---|---|---|
| 304 | Excellent | Moderate | Good | Food factories, commercial floors |
| 316 | Superior (marine) | High | Fair | Offshore, chemical, saltwater areas |
| 430 | Moderate | Low | Very Good | Decorative, less corrosive zones |
| 310S | High (heat-resistant) | Very High | Moderate | Furnace platforms, thermal plants |
4. Global Price Comparison: China vs USA vs India (2025)
Below is a price comparison for standard 4×8 ft, 3mm thick stainless steel checker plates in USD per metric ton as of June 2025.
| Country | 304 Checker Plate | 316 Checker Plate | Lead Time |
|---|---|---|---|
| China | $2,150 – $2,350 | $3,100 – $3,400 | 7 – 10 days |
| USA | $3,200 – $3,600 | $4,400 – $4,700 | 3 – 5 days |

8. Procurement Tips & Key Considerations
When sourcing stainless steel checker plate, ask yourself:
-
Are you in a corrosive environment? If so, go for 316.
-
Need food-grade hygiene? Choose 304 with a 2B finish.
-
Budget-tight and low-corrosion? Consider 430 with caution.
Checklist Before Purchasing:
✅ Confirm ASTM A240 or EN10088 compliance
✅ Verify supplier’s ISO certification
✅ Request MTC (Mill Test Certificate)
✅ Consider MOQ and delivery timeline
✅ Review the polishing and pattern sharpness
