Product Introduction
This product line covers custom precast terrazzo bar countertops engineered for commercial hospitality, retail, and corporate interior projects. Fabricated using high-performance cementitious binders or epoxy resin matrices combined with selected mineral aggregates (marble, recycled glass, granite), these countertops are cast, cured, and precision-machined to architectural shop drawings.
Standard Thickness: 30 mm, 40 mm, 50 mm (Custom thicknesses available up to 100 mm via mitered aprons).
Maximum Single-Piece Length: 3000 mm (epoxy resin) / 2400 mm (cement-based) to minimize visible joints.
Core Materials: Portland cement matrix (interior/exterior) or UV-stable epoxy resin matrix (interior high-traffic).

Key Product Features
Seamless Joint Technology: Factory-mitered drop edges and precision 45-degree corner joints executed via CNC waterjet cutting, reducing on-site grouting time.
Aggregate Distribution Control: Vacuum-vibration casting eliminates subsurface voids, ensuring uniform aggregate dispersion even after 10 mm of surface grinding.
Substrate Integration: Pre-drilled threaded inserts or embedded steel frames cast into the underside for direct mechanical fixing to millwork cabinetry.
Edge Profile Versatility: Fully machined bullnose, eased, sharknose, and laminated drop-apron profiles matching exact project specifications.
Colors, Patterns & Surface Finishes
Aggregate Options
Marble Chips: Carrara white, Nero Marquina, Botticino (Sizes: #0 to #8 granulate).
Recycled Content: Post-consumer mirror glass, colored bottle glass, industrial quartz.
Surface Finishes
Honed (Matte): 400-grit smooth finish; low light reflection, recommended for high-traffic bars.
Polished: 800+ grit mirror finish; high gloss, accentuates aggregate contrast (sealed with penetrating impregnator).
Leathered / Brushed: Textured tactile finish; hides minor surface scratches and fingerprints.
Sandblasted: Slip-resistant texture, suitable for transitional indoor-outdoor bar service areas.
Applications
Hospitality Venues
Hotel lobby bars, rooftop cocktail lounges, nightclub service stations.
Food & Beverage
Restaurant focal bars, café service counters, brewpub tasting bars.
Commercial Interiors
Corporate breakout pantries, reception greeting desks, retail cash wraps.
OEM & ODM Customization
Shop Drawing Execution: Production proceeds strictly upon client sign-off of CAD/PDF shop drawings detailing cutouts for sinks, beer towers, speed rails, and LED channel recesses.
Custom Color Matching: Send physical material samples or Pantone/RAL color codes; laboratory pigment blending delivers custom matrix colors within a 5-day turnaround.
Integrated Hardware: Factory-routing and stainless steel bracket embedding for under-counter equipment mounting.
Manufacturing & Quality Control
Production Workflow
1. Batching & Mixing: Automated gravimetric dosing of binders, pigments, and graded aggregates to ensure batch-to-batch color stability.
2. Casting & Vibration: Material is poured into rigid steel molds and consolidated on multi-axis shaking tables to purge air entrapment.
3. Curing Cycle: Temperature-controlled wet curing (cement matrix) or thermal-curing ovens (epoxy matrix) to achieve full structural polymerization.
4. Calibration & Calibrating: Slab calibration through diamond-head grinding machines guarantees uniform thickness across all countertop runs.
Quality Inspection Protocol
Dimensional Check: Caliper and laser measurement verifying length, width, and thickness tolerances within +/- 0.5 mm.
Flatness Verification: Straightedge testing across diagonal spans to ensure warpage does not exceed 0.2% of total span.
Surface Defect Audit: Inspection under 500-lumen lighting to detect micro-pinholes, aggregate pop-outs, or hairline cracks prior to factory sealing.
Packaging & Documentation
Export Packaging Standards
Crate Construction: Fumigated ISPM 15 compliant heat-treated plywood crates.
Internal Protection: Countertops are separated by 10mm EPE foam sheets, edge-protected with heavy-duty plastic corner guards, and secured with internal timber bracing to prevent shifting during ocean freight.
Max Weight Per Crate: Controlled under 1500 kg for safe crane and forklift handling at destination ports.

FAQ
Q: How do cement-based and epoxy-based terrazzo countertops differ in commercial bars?
A: Cement-based terrazzo offers authentic mineral aesthetics and higher thermal resistance, requiring a penetrating sealer to prevent staining. Epoxy-based terrazzo provides higher flexural strength, zero water absorption, and superior resistance to acids (citrus/wine), making it optimal for high-spill cocktail bars.
Q: What is the standard lead time for custom project orders?
A: Sample approval takes 7 business days. Mass production for container-load orders typically requires 20 to 30 days upon shop drawing confirmation.
Q: How are long bar runs joined on-site to minimize visible seams?
A: Slabs are cut at 90-degree or mitered angles using CNC bridge saws. We supply color-matched epoxy adhesive kits formulated to match the matrix color, allowing installers to achieve a near-seamless butt joint.
Q: Can cutouts for beer taps, sinks, and speed rails be pre-machined?
A: Yes. All sink cutouts, faucet holes, and drainage grooves are CNC-routed at the factory according to your exact equipment cut sheets.
