Series positioning: Selecting high-end engineering stone inspired by the fish-belly-white quarry tradition, the RUNPIN Quartz Calacatta Series reshapes various spatial styles and practical textures. As a reliable OEM/ODM quartz source manufacturer, RUNPIN creates customizable quartz slabs with natural antibacterial advantages suited for diverse interior design needs.
6374 is a premium surface from the RUNPIN Quartz collection, engineered for architects, designers, and project owners who demand the elegance of natural stone with the consistency, hygiene, and structural reliability of engineered quartz. Combining high-purity quartz aggregate with advanced resin technology, 6374 delivers a clean, refined surface that holds its color, gloss, and detail across decades of use.
6374 features a light white base with soft grey-blue wavy veining interwoven across the surface in a delicate, fluid pattern—creating an airy, refined aesthetic that feels effortlessly elegant. The gentle blue undertone distinguishes it from purely grey Calacatta patterns and gives interiors a cool, fresh, spa-like atmosphere. |

Built for longevity and ease of maintenance, 6374 combines the following performance advantages:
near-zero water absorption (0.02%): preventing staining, swelling, mold, and bacterial penetration even in wet areas such as bathrooms, kitchens, and pool surrounds.
stain resistance: the non-porous structure blocks liquid penetration; coffee, wine, soy sauce, oil, and cosmetics wipe off easily, keeping the surface spotless long-term.
heat resistance: with a melting point above 1300°C, the slab withstands hot pots and pans directly without cracking or discoloration under kitchen heat.
scratch resistance: with over 90% quartz content and Mohs hardness 5–6, the slab resists scratches from daily utensils and impacts, staying durable and long-lasting.
UV-stable pigments: resisting fading under prolonged sunlight, suitable for bright interiors and sheltered exterior walls.
finish options: available in polished, matte (honed), and sandblasted (lychee) finishes to match design intent across residential and commercial projects.
hygiene certification: NSF food-safe certified; the non-porous surface resists bacteria and buildup and can be wiped clean with water only, ideal for kitchens and dining areas.
large-format slabs: 3200×1600 mm, 3200×1800 mm, 3200×1850 mm, and 3500×2000 mm (custom cut-to-size available) reduce joints in walls, floors, and countertops for a cleaner, more continuous appearance. |
The wavy, interwoven lines of 6374 were inspired by the movement of water—currents meeting and layering in slow, sinuous patterns. The design team introduced a soft blue-grey tone to the veining, echoing the cool cast of natural stones found near coastal quarries. The fluid, unbroken waves make the pattern especially suited to organic, biophilic interiors, and they pair naturally with pale woods, brushed nickel, and soft linens.
Manufactured by Shenzhen Runfeng New Material Technology Co., Ltd., a subsidiary of China Resources Building Materials Technology Holdings, 6374 is produced on the Italian BRETON fully automated production line with vacuum vibration, pressing and curing. The slab is formed from natural quartz aggregate (over 90%) blended with high-purity resin and mineral binders, then vibro-compressed under vacuum and heat-cured to deliver a dense, non-porous body with outstanding mechanical strength. Every production batch is checked against the same color and pattern standards, so slabs ordered months apart arrive with matched tone and veining. The result is a surface that resists staining, scratching, moisture, and bacterial growth—qualities that make it suitable for kitchen countertops, healthcare interiors, hospitality surfaces, and high-traffic public spaces.
6374 brings a breath of cool air into any room. Its grey-blue waves on a light white base read as serene and contemporary, complementing bathrooms, spas, and calm residential kitchens. The soft blue cast also works beautifully with white and grey cabinetry, and the fluid lines help surfaces feel longer and more continuous when installed as large slabs.
From international hotel brands to regional developers, RUNPIN quartz materials have proven their long-term value in demanding commercial and residential environments. The Calacatta-inspired collection has been specified for kitchen islands, bathroom vanities, hotel feature walls, reception desks, and stair details across residential, hospitality, and commercial projects worldwide. The combination of large-format availability, color consistency, and certified performance makes 6374 a reliable choice for international specification teams.
Choosing 6374 reduces environmental pressure on natural stone quarries while delivering the same visual luxury. The dense, non-porous body requires no sealing or chemical treatments, and the long-term durability of the slab ensures it remains in service for decades without replacement. RUNPIN operates with minimum recycled materials, renewable electric energy, and reused process water, and every slab is produced with low-carbon, eco-friendly processes that support green building certification goals.
Day-to-day care for 6374 is simple: wipe with a soft damp cloth and a neutral pH cleaner, rinse, and dry. Avoid harsh acids, alkaline products, and abrasive scrubbers. For polished surfaces, occasional buffing with a quartz-safe polish restores gloss; honed and lychee finishes are inherently forgiving and naturally mask minor marks. Because the body is non-porous, there is no need for sealing, waxing, or periodic re-application of protective coatings—an important cost advantage over natural stone and porcelain alternatives.
The material can be fabricated into large-format wall panels, stair treads, vanity tops, reception desks, bar counters, and sculptural elements. RUNPIN's technical team supports shop drawing review, vein-matching optimization, and on-site installation guidance for complex assemblies, and offers cut-to-size and custom fabrication for projects that require non-standard dimensions, edge profiles, or integrated sink and drain details.
