Gloss board orange Marble wall staircase

Production Process & Machinery

Block Preparation

Process: Raw marble blocks are inspected for fractures/vein consistency.

Machinery: Gantry cranes for handling; diamond wire saws for trimming blocks into manageable sizes.

Slab Cutting

Process: Blocks are sliced into thick slabs (e.g., 3cm).

Machinery: Gang saws (multi-blade saws) or diamond wire saws for precision cuts.

Surface Calibration

Process: Slabs are ground to uniform thickness (e.g., 2cm).

Machinery: Automatic calibrating machines with diamond grinding heads.

Polishing (Gloss Finish)

Process: Sequential polishing with finer abrasives to achieve mirror-like shine.

Machinery: Automatic polishing lines with 6–10+ diamond abrasive heads (grit 60–3000+).

Cutting & Profiling

Process: Slabs cut to staircase wall dimensions; edges profiled (e.g., bullnose for safety).

Machinery: CNC bridge saws with diamond blades; edge polishers for profiling.

Resin Treatment (Optional)

Process: Epoxy resin fills micro-cracks/pores to enhance strength and gloss.

Machinery: Resin application lines with UV curing ovens.

Quality Inspection & Packaging

Process: Final checks for defects; foam-wrapped and crated for shipping.

Machinery: Automated optical inspection systems; suction lifters for handling.

Critical Quality Control Measures

Material Selection

Reject blocks with excessive fractures, discoloration, or inconsistent veining.

Precision Calibration

Ensure thickness uniformity (±0.5mm tolerance) to prevent uneven installation.

Gloss Consistency

Measure gloss with a gloss meter (target: 60–90° reflectivity at 60° angle).

Avoid "orange peel" texture (caused by rushed polishing).

Edge & Corner Integrity

Check for chips/cracks; reinforce edges with resin if needed.

Vein Matching

Arrange slabs to align veins seamlessly across staircase panels.

Surface Defect Detection

Use automated scanners to identify pinholes, scratches, or resin spots.

Moisture & Stain Testing

Apply water/oil to samples; ensure sealed surfaces resist absorption.

Key Success Factors

Diamond Tool Quality: Use premium blades/abrasives to avoid micro-fractures.

Polishing Speed Control: Overheating during polishing dulls the finish.

Resin Curing: Under-cured resin causes yellowing; UV ovens must be calibrated.

Handling Protocols: Minimize slab-to-slab contact to prevent edge chipping.
