Quartz Kitchen Countertops Wholesale Supplier

Engineered quartz countertops consist of approximately 90‑95 % ground natural quartz aggregate bound with polymer resins and pigments. This composition yields a non‑porous surface that resists liquid absorption and microbial growth.

Material Composition and Properties

The quartz aggregate provides hardness comparable to natural stone, while the resin matrix contributes flexibility and impact resistance. Typical slab density ranges from 2.3 to 2.5 g/cm³, and the flexural modulus falls between 10 and 12 GPa.

Technical Specifications

Manufacturing Tolerances and Customization

Standard slab dimensions are 3050 mm × 1440 mm with thickness options of 12 mm, 20 mm, and 30 mm. Tolerances on length and width are held within ±2 mm, while thickness variation stays within ±0.5 mm. Edge profiles such as eased, beveled, bullnose, and ogee can be produced via CNC routing to meet project specifications.

Applications in Commercial Kitchens

The non‑porous nature of quartz prevents bacterial harborage, making it suitable for food preparation zones where hygiene standards are strict. Resistance to common kitchen acids (citric, acetic) and oils reduces the need for sealing, lowering lifecycle maintenance costs. Additionally, the material’s consistent coloration supports branding requirements for chain restaurants seeking uniform appearance across locations.

Quality Control and Testing

Each slab undergoes visual inspection for color consistency and surface defects under standardized lighting. Dimensional checks are performed using calibrated laser scanners to verify thickness and flatness. Representative samples are subjected to chemical resistance testing per ISO 28701 and impact resistance testing per ASTM D5420 to ensure performance under expected service conditions.

Packaging and Logistics

Slabs are wrapped in low‑density polyethylene film and placed on wooden pallets with corner protectors. Pallets are strapped and stretch‑wrapped to prevent movement during transit. For container loads, a maximum of 20 slabs per 20‑foot container is typical, depending on thickness, to maintain safe weight limits.

Frequently Asked Questions

Can dimensions be customized?

Yes. Custom cuts, cut‑outs for sinks or appliances, and specific edge profiles are produced according to shop drawings provided by the client.

What information is required before quotation?

Project details such as slab size, thickness, edge treatment, quantity, and delivery destination enable an accurate cost estimate.

What materials are available?

Standard quartz blends in a range of colors from solid whites to patterned veining; custom color matching is possible upon request.

How is quality inspected?

Inspection includes visual, dimensional, chemical resistance, and mechanical testing as described in the quality control section.

What packaging methods are available?

Standard packaging uses PE film and palletizing; specialized crating or foam padding can be arranged for fragile edge profiles.

How are export shipments protected?

Pallets are secured with strapping and stretch wrap; additional corner boards and shock‑absorbing layers are used for long‑haul shipments.

What is the typical production lead time?

Lead time varies with order size and customization but generally falls between 2‑4 weeks after receipt of approved drawings.

How are samples arranged?

Small sample tiles (100 mm × 100 mm) can be shipped via courier; charges are credited against the first order.
