Seseam Yellow: The Granite natural stone tile Contractors Keep Requesting
I’ve walked more quarries and job sites than I can count, and—honestly—granite still surprises me. Seseam Yellow (Item NO.: SMC-FS090) is one of those quiet performers: warm, durable, easy to pair with timber or corten steel. It’s cut in that “free form” style architects love right now. And yes, the market momentum around natural stone tile—especially textured, slip-resistant finishes—is real.

What’s trending (and why it matters)
- Textured exteriors: split-face and flamed finishes for safer pool decks and patios.
- Free-form geometry: irregular formats that look organic, not factory-perfect.
- Responsibly sourced stone: traceable quarry-to-factory processes, ISO-backed QC.
- Low-maintenance surfaces: sealed granite that shrugs off stains and UV.

Product snapshot: Seseam Yellow Squar Free Form Natural Stone
Origin: YIJIA COMMUNITY 2-2702, YIHONG ROAD, XINYUAN DISTRICT, SHIJIAZHUANG CITY, HEBEI PROVINCE, CHINA. Material: Granite. A warm yellow-beige field with fine peppering—plays nicely with greenery and light stucco. Many customers say it feels “coastal” without being loud. To be honest, that versatility is why specifiers keep it on mood boards.
| Item NO. | SMC-FS090 | Material | Granite |
| Typical size | Free-form, 200–600 mm edges (≈); thickness around 20–30 mm | Finishes | Split-face, flamed, tumbled (as needed) |
| Water absorption | ≈0.2–0.5% (ASTM C97) | Compressive strength | ≈130–200 MPa (ASTM C170) |
| Mohs hardness | 6–7 | Slip resistance | DCOF ≥0.42 (ANSI A326.3); exterior flamed can test higher |
| Service life | 25–50+ years with basic care | Use zones | Patios, pool decks, facades, lobbies, walkways |
Values are typical; real-world use may vary by lot and finish. Request current test reports.

From quarry to crate: process flow and QC
- Source granite blocks; color/vein controlled at quarry face.
- Primary cutting; free-form templating; edge dressing (hand + CNC as needed).
- Surface treatment: flamed or split-face for traction; optional tumbling.
- Testing: ASTM C97/C170, DCOF (ANSI A326.3). Batch retention samples archived.
- Sealing (when specified), packing in fumigated crates, drop/impact checks.
Certifications: ISO 9001 for QC, ISO 14001 for environmental management; CE where applicable. Freeze–thaw suitability validated for exterior installs per EN 1341 guidance. It seems that the dimensional tolerance on free-form pieces is better than expected—edges are natural but thickness stays consistent.

Applications and feedback
Use Seseam Yellow natural stone tile in boutique hotel courtyards, resort pool surrounds, villa facades, and retail entries. One coastal resort reported “cool underfoot and no slipperiness even after rain”—always good to hear. Another client liked how the free-form pattern “breaks up long runs without looking busy.”
Customization and logistics
- Thickness: 15–40 mm (project-driven).
- Edge work: hand-chipped, eased, or machine-sawn (concealed joints).
- Patterns: random ashlar, opus, or fully bespoke cadenced sets.
- Lead time: around 3–6 weeks depending on volume and finish.

Vendor comparison (quick take)
| Factor | Sonmaci Stone (Seseam Yellow) | Regional Fabricator A | Import Aggregator B |
|---|---|---|---|
| Quarry-to-factory control | Direct sourcing; tighter color control | Mixed; depends on batch | Varied; multiple quarries |
| Slip-test documentation | ANSI A326.3 reports available | On request, not always current | Generic data, not finish-specific |
| Customization depth | High: free-form sets, special edges | Medium | Low–medium |
| Lead time (≈) | 3–6 weeks | 2–5 weeks | 6–10 weeks |
Indicative only; project size and seasonality affect all vendors.

Case note
A boutique resort (≈800 m² hardscape) selected Seseam Yellow natural stone tile in a random-set pattern. After 18 months of coastal exposure, on-site inspection showed stable color, intact edges, and wet DCOF within spec for flamed finish. Maintenance logs: neutral pH wash, reseal at 12 months—straightforward.
Bottom line: If you need free-form, slip-smart granite with a warm palette, this is a safe, good-looking bet. And, actually, it’s easier to stage than most irregular stones because thickness is consistent.
