Ensuring Quality That Speaks
Through Every Tile

At AQS, Step Tiles Tiles undergo rigorous testing — from raw materials to final finish.
Our quality control process ensures your walls reflect not just beauty, but trust

Step Tiles

Step tiles are specially designed with grooved or textured surfaces to provide slip resistance on staircases, platforms, and elevated areas, making them essential for safety in residential, commercial, and public spaces. Precise cutting, groove accuracy, and surface finish consistency are vital to ensure secure footing and prevent accidents.

At AQS, we conduct targeted inspections for step tiles, focusing on anti-slip properties, edge profiling, dimensional accuracy, and surface integrity. Our comprehensive checks ensure that each tile meets stringent safety standards and is installation-ready for high-traffic areas.

Step Tiles Slabs

We implement specialized inspection protocols for step tiles, focusing on anti-slip surface texture, groove accuracy, edge profiling, and dimensional consistency. Our comprehensive checks ensure each tile meets safety standards, provides secure footing, and is ready for reliable installation in high-traffic areas.

Factory Visit &
Order Quantity Verification

We begin by confirming that the total quantity produced matches the client’s purchase order. Step tiles are usually manufactured in smaller batches, so completeness and segregation are critical.

01

Warehouse Stock &
Batch Identification

Our inspector verifies:

  • Proper stacking and labeling of pallets
  • Clear identification of design codes and sizes
  • Safe storage conditions (no edge damage during stacking)

02

Random Sampling
by AQL Method

We select boxes randomly from different pallets using AQL guidelines. Since step tiles are directional and functional, it’s important to evaluate from across the lot to detect any cutting or finish inconsistencies.

03

Box Weight
Check

Boxes are weighed to ensure:

  • Proper tile count and material density
  • No missing or broken tiles inside
  • Detection of moisture or under-packing

04

Transfer to
QC Area

Sampled boxes are shifted to a clean, flat, and well-lit QC area for detailed inspection.

05

External Box &
Artwork Check

We verify:

  • Product code, size, and factory details
  • Decor film sharpness and clarity
  • Consistency with approved client artwork
  • Label accuracy for identification and export use

06

Internal Packing
Quality Check

We examine:

  • Use of separators or foam between tiles
  • Alignment of tiles inside the box
  • Corner protection (especially for L-shape or heavy grooved tiles)

Improper packing in step tiles can cause edge chipping or corner breakage during transit.

07

Tile Laying &
Visual Inspection

Tiles are laid flat to simulate staircase installation. We examine:

  • Groove consistency: spacing, depth, and direction of anti-slip lines
  • Surface defects: glaze pinholes, uneven texture, sharp edges, surface warping
  • Color and finish uniformity (glossy/matte)
  • Cutting accuracy: especially for edge-finished or bull-nose tiles
  • Joint alignment between multiple pieces (if part of modular staircase systems)

We ensure that the grooved surface both looks uniform and functions properly for anti-slip performance.

08

Reference
Sample Matching

If available, we compare step tiles with a client-approved master sample to check:

  • Matching design, finish, and tone
  • Exact groove dimensions
  • Edge polish and texture consistency

09

Technical Testing &
Key Checks

Using multiple-point measurements, we check:

  • Dimensional Accuracy
  • Surface Flatness & Warpage (ISO 10545-2)
  • Breaking Strength / Modulus of Rupture (ISO 10545-4)
  • Anti-Slip / Groove Functionality Check
  • Scratch & Stain Resistance (if glazed)

10

Final Reporting &
Client Communication

All observations are compiled into a detailed report, including:

  • High-resolution images of laid tiles, groove close-ups, and any defects
  • Dimensional results and technical test summaries
  • Inspector's recommendation: Approve, Conditional, or Reject
  • Shared with client within 24 hours

Why Step Tile Inspection Is Critical

Step tiles are essential for safety and functionality, where even minor flaws in groove depth, edge alignment, or surface flatness can lead to slip hazards and installation problems. Ensuring defect-free tiles is crucial to maintaining safety standards and preventing costly claims.

At AQS, we verify groove precision, structural integrity, and packaging quality, ensuring each tile is durable, slip-resistant, and export-ready. Our inspections protect your reputation and provide confidence in shipping step tiles that are installation-ready and compliant with safety regulations.
