Grey Marble Sawn-Cut is an Iranian natural stone with a calm grey background, dense marble structure, minimal strong veining, and a natural factory-cut surface that retains fine saw marks. Unlike Honed or Polished marble, the Sawn-Cut finish receives little or no additional surface refinement after cutting, preserving a raw, matte, and technically clean architectural appearance.
The surface can range from relatively smooth to slightly textured depending on the cutting equipment, blade type, calibration, and stone structure. In some projects, the material may be lightly calibrated or minimally smoothed to improve dimensional consistency while preserving its characteristic saw-cut appearance.
Grey Marble Sawn-Cut can be considered for paving, sidewalks, curbstones, garden and villa flooring, landscape projects, architectural flooring, technical surfaces, and projects where a clean natural finish or a suitable base for further processing is required.
What Is Grey Marble Sawn-Cut?
Grey Marble Sawn-Cut is Grey Marble supplied with the natural surface created during industrial cutting.
Stone blocks are cut into slabs, tiles, curbs, or project-specific pieces using equipment such as gang saws, wire saws, or bridge saws.
Unlike more refined finishes, the exposed stone face is not subsequently polished to a reflective surface.
The result preserves the direct visual evidence of the cutting process.
What Is Grey Marble?
Grey Marble is a natural metamorphic stone with a compact crystalline structure and a visually restrained grey appearance.
The U.S. Geological Survey (USGS) explains that metamorphic rocks form when existing rocks are transformed by geological conditions including heat, pressure, and mineral-rich fluids. Marble is one of the common metamorphic rock types.
Typical characteristics of this Grey Marble include:
- Neutral grey background
- Natural variation between lighter and darker grey
- Limited strong veining
- Subtle natural tonal movement
- Dense crystalline structure
- A clean architectural appearance

What Is a Sawn-Cut Finish?
A Sawn-Cut finish is the natural surface left on stone after it is cut using industrial stone-processing equipment.
The cutting process typically leaves fine linear marks that follow the direction of the saw or wire.
The exact appearance depends on:
- Cutting equipment
- Blade or wire type
- Feed speed
- Stone structure
- Calibration requirements
- Any optional light surface smoothing
The result is generally:
- Matte or very low-reflection
- Flat with visible cutting marks
- Natural and technically direct
- Less refined than Honed or Polished stone
- Suitable either as a final finish or a base for further processing
More information about this treatment is available in the Karimi Stone Sawn-Cut Stone collection.
Visible Saw Marks
Fine saw marks are a normal characteristic of Sawn-Cut stone and should not automatically be interpreted as surface defects.
These marks are produced during cutting and may appear as subtle parallel lines across the stone face.
Their visibility can vary according to cutting technology and viewing angle.
For architectural projects, an approved physical sample should establish the acceptable saw-line character before production.
Sawn-Cut vs. Honed Grey Marble
| Characteristic | Sawn-Cut | Honed |
|---|---|---|
| Surface processing | Primarily cutting | Additional abrasive grinding |
| Surface marks | Fine saw marks may remain | Saw marks removed |
| Reflection | Low | Low |
| Surface feel | Raw to lightly textured | Smooth |
| Character | Technical and natural | Refined and matte |
For comparison, see Grey Marble Honed.
Sawn-Cut vs. Polished Grey Marble
The contrast between Sawn-Cut and Polished Grey Marble is more pronounced.
Sawn-Cut Grey Marble preserves cutting marks and has little direct reflection.
Polished Grey Marble passes through additional grinding and polishing stages until the surface becomes smooth and reflective.
Polishing normally creates deeper color and higher visual contrast, while Sawn-Cut retains a more direct and unfinished material character.
Sawn-Cut as a Base for Further Processing
Sawn-Cut stone is frequently the starting surface for additional finishes.
Depending on the project, it can later be processed into:
- Honed
- Polished
- Sandblasted
- Brushed
- Grooved
- Bush-Hammered
- Other project-specific textures
This makes Sawn-Cut material useful both as a final architectural product and as semi-finished material for further fabrication.
Plain Natural Pattern
The current product is classified as Plain.
Strong directional veins are therefore not the dominant feature.
Its appearance is mainly defined by:
- Neutral grey color
- Soft natural tonal variation
- Fine cutting marks
- Low surface reflection
This restrained visual character is useful across large paving and landscape areas where excessive pattern variation is not desired.
Surface Grip and Slip Performance
The natural saw texture can provide more physical surface character than a highly polished stone.
However, Sawn-Cut should not automatically be assigned a specific slip-resistance rating.
The level of grip depends on the actual saw texture, stone type, wear, contamination, water, installation slope, and other project conditions.
Where a project requires a particular P-rating, Wet Pendulum result, coefficient of friction, or regulatory classification, the actual finished material should be tested.
Technical Characteristics
| Property | Current Product Value | Reference |
|---|---|---|
| Porosity | 0.9% | ASTM C97 |
| Density | 2700 kg/m³ | ASTM C97 |
| Water Absorption | 0.15% | ASTM C97 |
| Compressive Strength | 51 MPa | ASTM C170 |

These values represent the current Karimi Stone product data. Natural stone properties may vary between quarry blocks and production batches, so engineering specifications should be confirmed for the actual material selected for the project.
Applications of Grey Marble Sawn-Cut
Paving
Grey Marble Sawn-Cut can be considered for architectural paving where a simple, technically direct stone surface is desired.
Possible applications include:
- Villa courtyards
- Pedestrian areas
- Entrance spaces
- Landscape paving
- Public circulation areas
- Project-specific modular paving
Other paving materials can be explored in the Karimi Stone Natural Stone Paving collection.
Sidewalk Paving
The current product configuration includes sidewalk paving.
For urban applications, stone thickness, substrate design, traffic loading, joints, drainage, climate, and required surface performance should be coordinated with the project specification.
Curbstones
Curbstone is one of the primary configurations currently listed for Grey Marble Sawn-Cut.
The material can be produced in dimensional curb formats according to project requirements.
Important considerations include:
- Length
- Width
- Height
- Edge profile
- Installation method
- Traffic conditions
Garden and Villa Flooring
The neutral grey color works naturally with vegetation, timber, exposed concrete, brick, metal, and water.
The simple Sawn-Cut surface is particularly compatible with contemporary and minimal landscape architecture.
Further Processing
Sawn-Cut stone is also useful when the material will undergo final fabrication later in the production chain or at a project-specific fabrication facility.
Blocks, tiles, or other pieces can be selected as starting material before additional surface treatment.
Edge Finish
The Sawn-Cut term describes the main exposed stone face and should not be confused with the edge treatment.
Edge processing is a separate specification and may include Sawn, Chiseled, Tumbled, Split-Edge, or other project-specific profiles.
The exact edge should therefore be confirmed on the project quotation, product specification, and approved production drawing.
Cleaning and Maintenance
Routine maintenance should be adapted to the stone type and installation environment.
Recommended practices include:
- Regular removal of loose dirt and construction dust
- Use of cleaners compatible with natural marble
- Avoiding strong acidic cleaning products
- Using brushes appropriate for the actual surface texture
- Checking exterior drainage and joints
- Testing sealers before large-scale application
Available Formats
The current product configuration includes:
- Blocks
- Tiles
- Curbs
Additional custom dimensions may be coordinated according to project and production requirements.
Sorting and Quality Control
For project production, important criteria include:
- Grey background tone
- Acceptable tonal variation
- Saw-mark consistency
- Surface flatness
- Thickness
- Dimensional accuracy
- Edge specification
- Visual compatibility between adjoining pieces
For large projects, an approved sample should establish the acceptable natural color range and Sawn-Cut surface character before production begins.
