🧱 Types of Black Limestone Steps:
1 . General-Shaped Slabs – Uniform square or rectangular shapes for standard step designs.

To guarantee seamless installation and joint alignment, all black limestone step products are cut and finished with strict adherence to national dimensional tolerance standards.
📏 Technical Specification Standards for Black Limestone Steps
(1) Allowable Deviation in Dimensions
Thickness ≤ 15mm: Allowable thickness deviation is ±1.0mm per slab.
Thickness > 15mm: Allowable deviation increases to ±2.0mm.
Length & Width: May be slightly under the specified size, but not over.
Measuring Tools:
- Length & Width: Measured with a 1.0mm precision steel ruler.
- Thickness: Measured using a vernier caliper (accuracy of 0.1mm).
(2) Permissible Limit Tolerance of Flatness
Flatness affects how level the overall staircase surface will be after paving.
- Measured using a steel flat ruler across the diagonal axes of the slab.
- A feeler gauge is used to measure any gap between the ruler and slab surface.
- For slabs longer than 1000mm, a segmented measurement method is applied.
- The maximum gap size represents the slab’s flatness limit.
(3) Allowable Limit Tolerance of Angles
- Standard Shape Slabs: The angle between two adjacent sides must be exactly 90°, with tight tolerances.
- Special Shape Slabs: Tolerances are agreed upon by supplier and buyer.
- Measured using a precision 90° steel square and feeler gauge.
- The largest gap among two or four corners is used as the final tolerance indicator.
