Product Overview

Our grey vein quartz slab is a premium engineered quartz stone manufactured by Xiamen Smarter Stone. It features a grey base with natural-looking thin white veins, delivering the visual appeal of natural luxury stone with the superior performance of artificial quartz stone.

As a professional China quartz stone supplier, we control raw material formulation strictly to ensure uniform color and vein pattern across all production batches. All large quartz slabs support full customization, including custom size cutting, CNC milled edge profiles (straight edge, bullnose, ogee and more), and specified surface finishes.

We provide one-stop services including dry-lay pre-layout, batch labeling and custom processing for residential renovations, commercial fit-outs and large-scale construction projects. This dark quartz countertop material is widely used for kitchen countertops, vanity tops and interior wall cladding, balancing aesthetic performance and long-term durability.

Quality Control

All Grey vein quartz slabs go through systematic quality inspection before shipment. Our QC team performs color shading selection slab by slab to eliminate visible chromatic aberration in bulk orders. Flatness of each finished slab is controlled within +/- 0.5mm, with 100% edge inspection to prevent chipping and cracking.

All products comply with ASTM C97 and ASTM C128 test standards for physical performance. Each production batch is tested for water absorption, abrasion resistance and color fastness to verify long-term indoor service life.

For export packaging, we use ISPM-15 fumigated wooden crates with thick foam cushioning and drop-test safe structure, protecting slabs from damage during long-distance transportation. Full batch inspection reports are provided for large engineering orders.

FAQ

Q: Is this dark green vein quartz slab suitable for heavy daily kitchen use?

A: This engineered quartz has a non-porous surface with <0.2% water absorption. It resists oil stains, food acid corrosion and daily scratching, and requires minimal maintenance for long-term kitchen countertop use.

Q: How do you ensure consistent appearance for bulk quartz slab orders?

A: We adopt fixed raw material formula and standardized production parameters for all batches. Each slab passes color and vein screening to ensure no obvious difference for large-area wall cladding and countertop projects.

Q: Does this quartz slab need on-site sealing, and how to maintain it?

A: No on-site sealing is required, as the slab receives factory surface anti-fouling treatment. Daily cleaning uses clean water or neutral detergent; acidic and alkaline cleaners shall be avoided to protect the surface finish.
