Custom Factory Level 3 Quartz Countertops

Factory‑level quartz slabs are produced under tightly controlled conditions to achieve uniform thickness, consistent resin curing, and minimal internal voids. The result is a dense, non‑porous surface that meets the dimensional stability required for high‑precision installations.

Material Composition

The slab consists of approximately 90‑95 % natural quartz aggregate by weight, bound with a high‑performance polyester or epoxy resin system and inorganic pigments for coloration. This high quartz content contributes to a Mohs hardness of 7 – 8 and low water absorption.

• Quartz aggregate: 90‑95 %
• Resin binder: 5‑10 %
• Pigments and additives: <1 %

Manufacturing Process

Raw quartz is screened, washed, and dried before being mixed with resin and pigments under vacuum to eliminate air entrapment. The mixture is then pressed in a vibro‑compression mold at specific pressure and temperature cycles, followed by a controlled curing cycle that ensures full cross‑linking of the resin matrix.

• Aggregate preparation – cleaning and size grading
• Vacuum mixing – removal of entrapped air
• Vibro‑compression molding – forming the slab
• Thermal curing – resin polymerization
• Calibration and polishing – thickness tolerance & surface finish

Customization Options

Slabs can be tailored to project‑specific dimensions, edge treatments, and visual patterns while maintaining the core performance characteristics of the quartz‑resin composite.

• Thickness: 12 mm, 20 mm, 30 mm (custom upon request)
• Standard slab size: 3200 mm × 1600 mm (custom sizes available)
• Edge profiles: straight, bevel, bullnose, ogee, waterfall
• Color & pattern: solid colors, veined, speckled, custom digital prints
• Inserts: metal strips, LED channels, drainage grooves

Performance Characteristics

The following table lists typical values for factory‑level quartz countertops; actual values can be adjusted according to project requirements and resin formulation.

Applications

Because of its low porosity, chemical resistance, and consistent mechanical properties, factory‑level quartz is preferred in environments where hygiene, durability, and dimensional stability are critical.

• Laboratory worktops – resistance to acids, solvents, and biological stains
• Food processing surfaces – non‑porous, easy to sanitize, compliant with FDA standards
• Pharmaceutical manufacturing – minimal particle shedding, withstands frequent cleaning cycles
• Healthcare facilities – seamless surfaces reduce microbial harborage
• Commercial kitchens – high impact resistance and thermal stability

Quality Control

Each slab undergoes a series of inspections to verify dimensional accuracy, surface integrity, and color uniformity before leaving the factory.

• Thickness tolerance: ±0.1 mm measured at multiple points
• Flatness deviation: ≤0.5 mm over 1 m length (laser scanning)
• Color consistency: ΔE < 2 under standardized lighting (CIELAB)
• Surface defect inspection: automated vision system for pits, scratches, and inclusions
• Edge quality: radius uniformity and finish roughness (Ra < 0.8 µm)

Packaging & Shipping

Slabs are stacked on A‑frame pallets with corner protectors, interleaved with polyethylene sheets, and secured with steel straps. A moisture‑barrier wrap and UV‑stable cover protect the surface during transit.

• Pallet size: 1200 mm × 1000 mm, load capacity up to 2 tonnes
• Corner protectors: reinforced polypropylene, 45 mm × 45 mm
• Interleaving: 0.05 mm LDPE sheets to prevent abrasion
• Strapping: 16 mm galvanized steel, tensioned to 250 daN
• Outer wrap: 3‑layer co‑extruded film with UV inhibitors

Frequently Asked Questions
