201 Stainless Steel Checkered Sheet Diamond Plate Anti Slip Corrosion Resistant
The 201 Stainless Steel Checkered Plate (also known as diamond plate, tread plate, or chequered plate) features a raised diamond pattern on one side and a smooth reverse side. This design provides excellent anti-slip properties while maintaining the durability and corrosion resistance of stainless steel.
Grade 201 is an austenitic chromium-manganese stainless steel developed as a cost-effective alternative to 304 grade. It offers good mechanical properties and workability, making it suitable for a wide range of industrial and decorative applications where high nickel content is not critical.
Key advantages:
-
Anti-Slip Surface: Raised diamond pattern provides excellent traction in wet or slippery conditions
-
Cost-Effective: More economical than 304 grade for non-critical applications
-
Good Mechanical Strength: High tensile and yield strength suitable for structural uses
-
Corrosion Resistant: Adequate resistance for indoor and mild outdoor environments
-
Easy Fabrication: Can be cut, bent, welded, and formed using standard equipment
-
Low Maintenance: Easy to clean and sanitize, with good hygienic properties

A checkered plate (also known as diamond plate, tread plate, or chequer plate) is a metal sheet with a regular pattern of raised diamonds or lines on one side. The reverse side remains smooth and featureless.
Common Names:
-
Stainless Steel Diamond Plate
-
Stainless Steel Tread Plate
-
Stainless Steel Chequered Plate
-
Stainless Steel Checkerboard
-
Anti-Slip Floor Plate
Pattern Types Available:
| Pattern | Description |
|---|---|
| Diamond | Standard raised diamond shape – most common for anti-slip flooring |
| Lentil | Round bean / lentil shape pattern |
| 5-Bar | Five raised bars pattern for specialized applications |
How It's Manufactured:
The checkered pattern is created by passing stainless steel coils or sheets through embossing rollers under high pressure. The rollers have a concave-convex pattern that transfers the design onto the metal surface. The material is then leveled, cut to length, and packaged.
To protect the checkered surface and ensure safe delivery, each plate is carefully packed for international transport:
| Step | Packaging Detail |
|---|---|
| 1. Interleaving | Kraft paper or foam sheet between each plate to prevent surface scratching |
| 2. Moisture Protection | VCI (Volatile Corrosion Inhibitor) paper and PE film wrap |
| 3. Edge Protection | Cardboard or plastic edge protectors on all four sides |
| 4. Securing | Heavy-duty steel or plastic strapping (2–4 straps per pallet) |
| 5. Palletizing | Export-standard, ISPM 15 certified fumigated wooden pallets |
| 6. Bundle Weight | Approximately 2 metric tons per bundle (customizable) |
| 7. Optional | Waterproof shrink-wrap and corner guards for sea freight |
| 8. Marking | Neutral sticker or custom labeling with product specifications |
Custom packaging solutions available upon request.
