A Supplier, Not a Reseller
Most “slab suppliers” broker other people’s stock. We Quarry It. We Cut It. We Deliver It. — Citadel Stone works quarry-direct at our selected quarries and through our own fabrication services, which is why wholesale buyers, fabricators and developers come to us for volume: consistent material lot to lot, container-scale logistics handled end to end, and a certificate behind the datasheet instead of a brochure claim. Indicative pricing runs from $1.96/sq ft ex-works (indicative — final pricing quoted per order and specification).
The Stone, Certified
Every slab comes from the same white limestone family sold across our pavers, tiles and pool coping — five varieties (Pearl White, Bianco Velo, Royal Cream, Citadel Alabaster, Crema Aurora) differing in tone, not performance.
| Property | Certified value (certified mill test) | ASTM C568 Type II threshold | Notes |
|---|---|---|---|
| Density | 154.8 lb/ft³ (2.48 g/cm³) | 135–160 lb/ft³ | Within the Type II band |
| Water absorption | 1.61% | ≤ 7.5% | Governs freeze–thaw behaviour |
| Compressive strength | 4,850 psi (33.44 MPa) | ≥ 4,000 psi | — |
| Modulus of rupture | 1,073 psi (7.40 MPa) | ≥ 500 psi | Roughly double the minimum |
| Flexural strength | 7.31 MPa | — | C568 sets no flexural threshold |
| Abrasion resistance | 2.68 mm Böhme | — | Certified mill test (DIN 52108) |
| Wet DCOF, per finish | Will be published here | — | Method: ANSI A326.3 |
Read against the specification architects actually cite: our certified mill values meet every threshold ASTM C568 sets for Type II (medium-density) limestone — density inside the 135–160 lb/ft³ band, 1.61% absorption far under the 7.5% ceiling, 4,850 psi compressive above the 4,000 psi floor. Where your project spec requires verification to a named ASTM method, test reports are arranged on request against the order.
Cut to Size — Any Size. Any Thickness.
Slabs are where cut-to-order earns its keep: large formats, custom dimensions, matched step treads, radius work and bespoke thicknesses, produced through our own fabrication services against your drawings. Every piece is available in any finish — brushed in several grits, bush-hammered, honed, polished, antique or tumbled — because finishing happens at fabrication, not at the catalogue. See the range on our stone finishes page.
How Wholesale Supply Works
Simple, and built for volume: send your formats, finishes, thicknesses and quantities through a quote request; we return pricing against your exact specification, ex-works. Free samples of the varieties on your shortlist ship on request. Production runs at our fabrication services; we handle export logistics through to the port; you or your forwarder take over from there. Container-scale programs are our normal work — including a 70,000+ sq ft combined white limestone and Ocean Reef shellstone supply program delivered to a single U.S. design-build firm.
Distributors and trade buyers: the trade & wholesale program carries standing terms, and for multi-material programs beyond this family, talk to us as your wholesale stone supplier.
Where Slabs Are Specified
Facades and cladding panels, stair treads and landings, wide copings and wall caps, countertops and vanities, and large-format exterior paving cut from the same lots as the field material — so a project’s verticals and horizontals match.
