3) Prefab size of natural stone skirts

 

Prefabricated Sizes and Thickness

• Standard Thickness: Generally ranges from 1 cm (about 3/8 inch) to 2 cm (about 3/4 inch).

• Common Heights: Typically between 7 cm (about 2.75 inches) and 15 cm (about 6 inches).

• Lengths: Can vary widely but often come in lengths matching door widths or room perimeters to minimize seams.

 

4) Processing and Machine

 

1. Production Process & Machinery​​

 

​​Step 1: Slab Selection & Inspection​​

 

•​​Machine​​: Bridge saw with diamond blade

​​•Process​​: Handpick Grade-A slabs with balanced veining; reject cracked or resin-filled sections.

 

​​Step 2: Cutting to Rough Size​​

 

​​•Machine​​: CNC waterjet or diamond saw

​​•Process​​: Cut slabs into rectangular blocks (e.g., 5"x30" for standard skirts) with ±1mm precision.

 

​​Step 3: Edge Profiling​​

 

•​​Machine​​: CNC edge-shaping machine with diamond wheels

​​•Process​​: Create smooth, eased, or bullnose edges; polish to 600-grit finish.

 

​​Step 4: Surface Finishing​​

 

•​​Machine​​: Automatic polishing line (for glossy finish) or honing machine (for matte)

•Polished: 7-stage abrasives (50-grit to 3000-grit).

•Honed: 200–400-grit pads for uniform matte texture.

 

​​Step 5: Quality Control & Sealing​​

 

•UV light inspection for hidden cracks.

•Apply impregnating sealer (e.g., Tenax Proseal).

 

​​Step 6: Packaging​​

 

​​•Process​​: Foam-lined crates with corner protectors.

 

 

​​2. Key Factors for Quality Assurance​​

 

✅ ​​Material Integrity​​

 

•Use slabs with ≥95% natural stone (no "plastic-feeling" resin-heavy batches).

•Avoid slabs with "wet spots" (indicate internal fractures).

 

✅ ​​Precision Standards​​

 

•hickness tolerance: ±0.5mm (e.g., 20mm nominal).

•Length/width tolerance: ±1mm.

 

✅ ​​Finish Consistency​​

 

•Polished: No swirl marks or cloudy patches.

•Honed: Even texture (no rough or glossy streaks).

 

✅ ​​Structural Stability​​

 

•Reinforce long pieces (>36") with fiberglass mesh backing.

 

✅ ​​Sealing Effectiveness​​

 

•Water droplets must bead (not absorb) on the surface.

 

​​3. Red Flags to Avoid​​

 

❌ ​​Resin Overuse​​: Cloudy patches indicate low-quality repairs.

❌ ​​Warping​​: Check flatness with a straightedge (≤0.3mm deviation).

❌ ​​Poor Packaging​​: Inadequate padding risks chipped edges.
