Factory Visit &
Order Verification

We begin by:

• Checking produced quantity vs. PO
• Verifying size, thickness, and design (e.g., Carrara, Calacatta, speckled, mirror-fleck)
• Confirming batch codes, pattern names, and surface finish (polished, matte, suede)

01

Warehouse Stock
Condition Check

We assess:

• Slab storage on A-frames or vertical metal racks
• Cut-to-size material stacked on foam-lined wooden crates
• Labeling of each slab/set with design name, batch, and thickness

02

Random Sampling of
Slabs / Cut Pieces

Using an AQL-based approach, we randomly select:

• Full-size slabs from various batches and positions
• Cut pieces from different crates (e.g., countertops, backsplashes, islands)

03

Surface Quality &
Aesthetic Inspection

We conduct visual inspection under controlled lighting for:

• Surface consistency (no cloudiness, swirl marks, or resin pooling)
• Pattern uniformity across slabs
• Color consistency within batch
• Gloss level consistency (for polished finishes)
• Defects like pinholes, resin bubbles, blotches, or foreign inclusions

04

Edge Finish &
Corner Inspection

Edges are checked for:

• Straightness and smoothness
• Consistent polish on visible surfaces
• Chips or resin cracks on corners or cut-outs
• Bevel, bullnose, or chamfer accuracy (if edge shaping is done)

05

Size & Thickness
Measurement

We use digital calipers and measuring tape to verify:

• Slab dimensions (e.g., 3200x1600 mm or 3000x1400 mm)
• Cut-to-size accuracy (e.g., 600x600 mm, 800x300 mm)
• Thickness (typically 15, 18, 20, or 30 mm)
• Tolerances within acceptable limits (±1 mm)

06

Flatness &
Warpage Check

We check slab surface using:

• Long straight edge tools
• Visual observation for bowing or edge lift
• Bending or curve test for larger cut-to-size pieces

Flatness is essential for countertop application and proper adhesive bonding.

07

Backside Surface &
Resin Check

We inspect the rear side for:

• Uniform resin fill (no excess build-up or hollow areas)
• Mesh (if used) bonding quality
• No air pockets, cracks, or contamination

08

Gloss Meter / Polish
Quality Test

For polished slabs:

• We use a gloss meter to confirm gloss levels (typically 90+ GU)
• Check for uniform reflectivity across surface
• Evaluate visual depth of polish in veined or marble-look quartz

09

Stain Resistance /
Marker Test

We apply permanent marker or food-based liquids (e.g., coffee, lemon) and clean with water or mild cleaner to assess:

• Stain resistance of top resin layer
• Surface ease of maintenance — crucial for kitchen countertops

10

Fabrication Suitability &
Structural Check

We assess:

• Cutting smoothness along sink or hob cut-outs
• Internal stability for unsupported spans (especially 20+ mm thick slabs)
• Tap hole and corner strength in bathroom vanity pieces
• Dry tap test to identify hollow or weak areas

11

Packaging & Export
Readiness Check

We verify:

• Foam or plastic sheets between slabs
• Edge protectors and crate locking mechanism
• Crate labeling with slab numbers, thickness, and batch ID
• Weight markings and stacking safety
