Technical Specifications & Sourcing Guide

Wholesale Quartz stone slabs from China manufacturer

When sourcing quartz surfaces for high-traffic environments, physical performance metrics are critical. Our quartz slabs are engineered with a precise 93% natural quartz aggregate and 7% premium polymer resin binder, ensuring structural durability and non-porous hygiene. Below are the standard manufacturing specifications for our wholesale quartz lines.

Specification Parameter Value / Industry Standard
Material Composition 93% Natural Quartz Crystal, 7% Resin & Pigments
Mohs Hardness 6.5 - 7.0 (Scratch resistant)
Water Absorption Rate < 0.03% (Non-porous, stain resistant)
Standard Slab Dimensions 3000mm × 1400mm (118" × 55")
Jumbo Slab Dimensions 3200mm × 1600mm (126" × 63")
Standard Thicknesses 15mm, 18mm, 20mm, 30mm
Thickness Tolerance ± 1.0mm
Density 2.35 - 2.45 g/cm³

 

 

Material Composition and Fabrication Tolerances

Unlike natural stone variations, engineered quartz demands strict batch consistency. We operate industrial-grade vacuum vibro-compression press machines to eliminate air voids during the curing process. This results in a dense, predictable slab that minimizes tooling wear for fabricators.

For commercial cutting and profiling, our quartz maintains strict flatness tolerances (maximum warpage of 0.5mm across a 3-meter span). This structural predictability allows for precise mitered edges, waterfall islands, and large-format wall cladding without the risk of stress fractures during installation.

Why Partner with Our Quartz Factory? (Manufacturing Strengths & QC)

 

Selecting a reliable supplier requires looking beyond surface aesthetics to evaluate production capability and quality control. As an established source factory, we provide measurable advantages for volume buyers:

 

Production Capacity: Our facility operates multiple automated pressing lines, yielding a monthly output capacity exceeding 50,000 square meters (approximately 150 containers). This ensures on-time delivery for phased commercial projects.

 

Stringent Quality Control (QC): Every slab undergoes a 4-point inspection before packing. We measure gloss levels (minimum 50 gloss units), verify color uniformity against master samples using spectrophotometers, and check diagonal dimensional accuracy.

 

Certifications: Our manufacturing processes and finished products comply with CE, SGS, and NSF standards, making them suitable for food-prep zones and international commercial building codes.

 

Custom R&D (OEM/ODM): We offer color-matching services for specific architectural requirements. Submit a physical sample, and our lab will engineer a match with a 95%+ accuracy rate within 14 days.

 

Frequently Asked Questions

Q: What is the standard minimum order quantity (MOQ) for wholesale quartz slabs?

 

A: Our standard MOQ is one 20-foot full container load (FCL). This typically holds around 105 slabs of 20mm thickness or 70 slabs of 30mm thickness. We allow mixing up to 3-4 different colors per container.

 

Q: Can you match custom quartz colors or veining patterns for large commercial projects?

 

A: Yes. We have a dedicated R&D lab for custom color matching. Clients need to provide a physical sample of at least 10x10cm. We will produce a counter-sample for your approval before initiating mass production.

 

Q: How do you pack the quartz slabs to prevent transit damage?

 

A: All standard and jumbo slabs are packed using heavy-duty, fumigated wooden A-frames. Each slab face is protected by a PET film, and the bundles are securely strapped with steel tension bands to prevent shifting during ocean freight.

 

Q: Do you offer prefabricated quartz countertops in addition to raw slabs?

 

A: Yes. We have a dedicated fabrication workshop equipped with CNC bridge saws and automated edge-polishing machines. We can supply cut-to-size countertops, vanity tops, and island pieces based on your exact CAD drawings.
