Technical Specifications

Specification	Technical Details
Kiln Firing Tech	Fired in computerized natural gas tunnel kilns at 1280 deg C for 28 continuous hours, achieving complete vitrification.
Water Absorption Rate	< 0.15 percent (tested per ASTM C373 / ISO 10545-3), preventing moisture expansion, thermal cracking, and bacterial colonization.
Glaze Thickness & Hardness	Applied via multi-layer robotic spray glazing to a thickness of 0.7 mm to 0.9 mm, featuring a Mohs Scale Level 7 micro-crystalline enamel surface.
Dimensional Stability & Warpage Control	Controlled within a tight tolerance of plus or minus 1.2 percent across long spans exceeding 1200 mm, mitigating post-firing distortion.
Static Load Bearing	Center-point vertical load tested up to 350 kg without structural micro-fractures, backed by internal laboratory drop and weight test logs.
Global Compliance	Certified by cUPC (IAPMO), CE (EN 14688), WaterMark (AS/NZS 1730), and ISO 9001 quality management systems.

Key Features

Anti-Splash Basin Geometry:

Internal wall slopes engineered at a precise 72 degree angle, dissipating kinetic energy from commercial sensor faucets to eliminate water splashback.

Pressure-Tested Overflow Systems:

Integrated internal overflow conduits tested to withstand 0.3 MPa internal water pressure, preventing hidden leaks behind vanity front panels.

Chemical & Stain Resistance:

Non-porous nano-glaze finish resists industrial cleaners, organic staining, hair dye, and concentrated acids/alkalis (pH 2 to 12 tested per ISO 10545-13).

Universal Drain Compatibility:

Standardized 45mm waste outlet dimensions compatible with US, European, and Australian commercial grid drains and pop-up assemblies.

Installation Requirements

Concealed Wall Support:

Wall-hung double basins require heavy-duty concealed steel carrier brackets (such as Geberit or equivalent commercial frames) rated for a minimum shear load capacity of 450 kg.

Undermount CNC Cutouts:

Undermount models require precision CNC-machined stone or solid-surface cutouts following factory-supplied DXF CAD templates. A continuous 3 mm bead of neutral-cure silicone sealant is required at the basin-countertop interface.

Accessibility Clearance:

Install with a finished rim height of 850 mm to 865 mm to meet ADA and international universal accessibility codes.

Applications

Commercial Aviation & Transit Terminals:

Heavy-duty public washrooms managing continuous thousand-cycle daily use with zero downtime.

Hotels & Hospitality Complexes:

Guest suites and public corridor washrooms requiring uniform visual alignment, acoustic dampening during filling, and low-maintenance profiles.

Healthcare Facilities:

Scrub sinks and public sanitization stations complying with stringent hospital chemical washdown and infection control standards.

Corporate Headquarters:

Executive washrooms requiring clean architectural lines, heavy-gauge construction, and seamless integration with stone countertops.

Quality Control & Manufacturing Evidence

Raw Material Screening: High-purity ball clay, feldspar, and quartz undergo wet-sieve analysis and electromagnetic iron-removal filtration prior to high-pressure slip casting.

Multi-Stage Inspection Protocol:
Greenware & Moisture Audit: Automated moisture sensing and surface crack detection prior to kiln loading.

Laser Plane Flatness Scanning: Post-firing optical scanner mapping to measure surface camber and warpage across long-span double basins.

Acoustic Resonance Testing: Manual and automated acoustic tapping tests to detect internal micro-fissures or structural voids.

High-Lux Visual Inspection: 1000-lux LED inspection lines checking for pinholes, orange peel texture, and color batch uniformity.

Packaging, Palletization & Export Logistics

Heavy-Duty Export Cartons:

5-layer double-wall corrugated master cartons reinforced with corner impact protectors.

ISPM 15 Palletization:

Fumigation-free heat-treated wooden pallets (1200 x 1000 mm) secured with high-tensile polyester strapping and waterproof stretch wrap.

ISTA 3A Drop Testing:

Packaging protocols certified to withstand rigorous maritime vibration, multi-tier warehouse stacking, and port-to-port container transport.

Container Optimization:

40-foot high cube (40HQ) container space planning engineered to maximize volumetric efficiency and minimize per-unit shipping costs while maintaining a zero-breakage track record.

FAQ

Q: What is the standard production lead time for bulk wholesale orders?

A: Standard catalog models require 30 to 35 days from deposit receipt. Custom OEM tooling and pilot sample sign-off require an additional 25 to 30 days.

Q: What is the Minimum Order Quantity (MOQ) for custom dimensions or private labels?

A: The MOQ for custom mold development or dedicated color runs is 100 units per SKU, or mixed container arrangements negotiable based on production scheduling.

Q: Do your double bowl basins ship with installation hardware?

A: Basins are supplied as standalone units to integrate with project-specific vanity frames. Heavy-duty mounting brackets, anchor bolts, and grid drains can be bundled as optional project kit add-ons.

Q: How are transit breakages or manufacturing defects handled?

A: All shipments operate under standard FOB/CIF terms. Claims supported by photographic evidence of transit damage or structural defects are processed for replacement units or credit memos within 7 business days of inspection report submission.
