Checker Plate Spec Table
Checker Plate Specifications — 4 sizes
KS D 3503
SS400-based steel plate with anti-slip raised patterns (checkered plate), used for stairs, walkways, and truck beds. Thickness refers to base plate only.
Practical Notes
- Thickness refers to base plate only — total height = base + pattern height (about 1.5–2mm).
- Anti-slip is the primary function — replace when pattern wears down. Inspect wear condition regularly.
Selection Guide
For anti-slip floors, stairs, and covers. Raised surface pattern prevents slipping. Thickness notation refers to base plate excluding the pattern height.
