A rough block is where every slab starts, the raw, quarried piece before it’s ever touched a gangsaw. Getting this stage right matters more than buyers often realize: a block with hidden cracks or an off-grade cut wastes an entire production run downstream.
We supply rough granite blocks straight from the quarry, sorted and graded before they ever reach a buyer’s factory.
Blocks are cut to two different specifications depending on what they’ll be processed into.
For large-format slabs, cut on a multi-blade gangsaw:
Smaller, for single-blade cutting into tiles or smaller slabs:
Blocks are also graded by size for easier sourcing:
| Grade | Approx. Dimensions (cm) |
|---|---|
| Small | 120–180 x 60–90 x 60–90 |
| Medium | 180–240 x 90–120 x 90–120 |
| Large | 240–320 x 120–180 x 100–180 |
Custom sizes are cut on request where a factory’s gangsaw or cutting line needs a specific dimension.
| Property | Typical Range |
|---|---|
| Density | 2,600 – 2,900 kg/m³ |
| Compressive strength | 130 – 220 MPa |
| Water absorption | ≤ 0.5% |
| Porosity | Very low |
These figures vary slightly by color/variety, but give a reliable baseline for structural and durability assessments.
Blocks are supplied unfinished, in raw, rough, sawn, or rubbing-block form depending on how the quarry has already processed the piece before dispatch. No surface finishing is applied at this stage, that’s done after cutting, by the buyer’s own facility.
