Factory Visit & Production Confirmation

We begin with a factory-level verification of:

• Quantity produced vs. client order
• Sheet format (e.g., 300x300mm or customized size)
• Material type (glass, porcelain, ceramic, natural stone)
• Sheet layout (square, hexagon, herringbone, mix pattern, etc.)

01

Warehouse Storage &
Handling Check

We verify:

• Proper stacking of cartons or boxes
• Clear labeling of design, shade, and batch
• Safe packing to prevent sheet bending or chip detachment

02

Random Sampling
(AQL Method)

Using AQL guidelines, we randomly select boxes from multiple pallets to ensure representative inspection of the full lot.

03

Box Weight &
Packing Check

We weigh each box to verify:

• Correct number of sheets per box
• Standard weight per material type
• Detection of under-packed or over-packed boxes

04

QC Area
Transfer & Preparation

Selected sheets are moved to a clean, flat inspection table under proper lighting for:

• Visual evaluation
• Measurement tests
• Bonding strength checks

05

Labeling & Packaging
Verification

We check:

• Product design code and pattern name
• Sheet size and piece count
• Logo or branding (if applicable)
• Label positioning and legibility

06

Internal Protection & Sheet
Handling Check

We inspect:

• Use of interleaf paper or foam between sheets
• Protection from dust, edge pressure, and warping
• Adhesion strength of chips to mesh backing

Poor packing can lead to chip dislodgement or bending, especially in long-distance shipping.

07

Sheet Layout & Visual
Evaluation

We lay out sheets edge-to-edge to evaluate:

• Chip alignment across sheets (important for grout joints)
• Pattern continuity (especially for mix-material or gradient designs)
• Surface defects: scratches, color inconsistencies, edge chips
• Uniform grout gaps between chips
• Mesh visibility (should not appear through joints when grouted)
• Gloss/matte consistency (especially in glass/ceramic blends)

If applicable, we also check for:

• 3D or textured chip quality
• Printed design clarity
• Mixed material bonding

08

Adhesion Strength & Mesh
Bonding Check

We perform a manual bonding test on selected sheets to ensure:

• Chips are firmly fixed to the mesh
• No loose or weakly bonded pieces
• Mesh is aligned flat and not twisted or curled

This is critical for installation ease and sheet integrity during handling.

09

Size & Dimensional
Accuracy

We verify the overall sheet size (e.g., 300x300mm) for:

• Squareness and diagonal accuracy
• Consistent edge cutting
• Uniform sizing across multiple samples

We measure individual chips to ensure:

• Same width, length, and height (especially in modular patterns)
• Consistency of finish across the sheet

Even slight variations can distort the design when installed.
