Description

Black Marble Quartz Countertops with White Veining

The product combines natural quartz aggregates with a polymer resin matrix and mineral pigments to replicate the appearance of black marble while providing the performance benefits of engineered stone.

Material Composition and Manufacturing Process

Approximately 90% by weight is ground quartz, the remaining 10% consists of unsaturated polyester resin, pigments, and additives. The mixture undergoes vacuum vibration compaction to eliminate air pockets, then is cured in a heated press at up to 100 °C for a controlled period to achieve full polymerization.

Technical Specifications

Primary Applications

Kitchen countertops – low porosity prevents absorption of food liquids, reducing bacterial growth and simplifying cleaning.
Bathroom vanities – resistance to cosmetics, cleaning agents, and moisture ensures long‑term surface integrity.
Laboratory workbenches – chemical resistance to common reagents and ease of decontamination meet lab safety standards.
Hospitality reception desks – consistent veining pattern across large slabs provides a seamless, upscale appearance.
Retail display surfaces – high abrasion tolerance maintains aesthetic appeal under heavy foot traffic.

Quality Control and Testing

Each slab is inspected for thickness tolerance (± 0.5 mm), surface flatness (≤ 0.3 mm deviation over 1 m), and color uniformity. Veining alignment is verified against a master pattern using high‑resolution imaging. Representative samples undergo the mechanical tests listed in the specification table; any batch failing to meet the minimum compressive or flexural strength is rejected.

Customization Options

Slab thickness: 20 mm (standard for vertical applications) or 30 mm (preferred for horizontal countertops).
Maximum slab size: 3200 mm × 1600 mm; custom lengths available upon request.
Edge profiles: eased, beveled, bullnose, ogee, waterfall, and custom CNC‑machined designs.
Finish: polished (gloss > 80 GU), honed (matte 5‑10 GU), leather‑textured, or brushed.
Veining intensity: adjustable pigment dispersion to achieve subtle, moderate, or pronounced white veining against the black base.

Frequently Asked Questions

Q: Can dimensions be customized to fit specific project layouts?

A: Yes. Slabs can be cut to length and width, and edge profiles can be machined according to CAD drawings provided by the client.

Q: What information is required before a quotation is issued?

A: Project dimensions, desired thickness, finish, edge profile, veining preference, and any special cut‑outs (sink, cooktop) are needed.

Q: How is quality inspected before shipment?

A: Each slab undergoes visual inspection for color and veining consistency, dimensional verification, and a surface defect check using 45° lighting.

Q: What packaging methods protect the slabs during transit?

A: Slabs are packed in vertical A‑frames with corner protectors, foam edge guards, and stretch‑film wrapping; wooden crates are available for export shipments.

Q: What is the typical production lead time?

A: Standard lead time is 2‑3 weeks after receipt of approved shop drawings; expedited schedules are possible depending on plant capacity.
