Product Introduction
A leather top is a specification rather than a decoration, and on an Old G654 Granite Slab Leather Top it is the finish that decides how the stone behaves in use. The surface is cut mechanically, three passes with abrasive brushes then three with plastic brushes, which leaves a grainy matte face with no specular sheen; where a mill produces the texture by controlled hammer impact instead of brushing, the result is heavier and more tactile and the two are quoted as different textures rather than one finish. That grainy face is the commercial argument on a dark grey granite: a polished dark grey slab reads every water spot, fingerprint and smear of dust across an elevation, while a leather face scatters the light and does not show them, and the same texture lifts slip resistance on a floor walked on wet. Depth and evenness are the quality variables, because the texture is set by brush grit, the number of passes and the dwell of the head; an area where the head dwelled comes out burnished and darker than the field beside it, and over-brushing rounds the arris and cannot be reversed, so the face is read at a low angle against the light before it leaves the works.
Products Description
| Parameter | Specification |
|---|---|
| Product Name | Old G654 Granite Slab Leather Top; Original G654 Granite Slab with Leather Top; Brand: YoYo Stone |
| Also Listed As | old g654 granite slab leather top, original G654 granite slab, G654 dark grey granite slab, leathered granite slab, G654 leather top slab |
| Stone and Colour | Original G654, a dark grey granite from Fujian, China, shipped through Xiamen. A coarse-grained intrusive igneous rock, not a marble and not a basalt |
| Old and New G654 | Original G654 is the Fujian material, held as stock. New G654 is quarried in Shandong and is a different stone. They are quoted separately and never blended on one elevation |
| Leather Top Process | Three passes with abrasive brushes then three with plastic brushes, leaving a grainy matte face with no specular sheen. A heavier hammered texture is quoted separately |
| Texture Quality | Depth is set by brush grit, passes and head dwell. Read at a low angle for even grain, burnished patches where the head dwelled, and a rounded arris |
| Slip Resistance and Surface Performance | A matte grainy face scatters light, so water spots and fingerprints that a polished dark slab shows do not read on it; the texture lifts slip resistance on wet floors |
| Available Finishes | Leather top as specified. Also produced: polished, honed, flamed, sawn, flamed plus brushed, antique, pineapple, chiselled, sandblasted and water jet |
| Big Slab Sizes | 2800up x 1600up x 20/30/50mm |
| Semi Slab, Cut-to-size and Tiles | Semi slab 180-240up x 60-90cm and cut-to-size 30x30cm, 60x30cm, 60x60cm in 2/3/4cm; tiles 305x305x10, 400x400x10 and 610x305x10mm calibrated to +/-0.5mm |
| Countertop Sizes | 96x26 in, 108x26 in, 96x36 in, 72x36 in and 96x16 in at 3/4 in and 1 1/4 in; any drawing can be made |
| Thickness Tolerance | +/-1mm as the house standard, or +/-0.5mm on calibrated tile |
| Stone Data | Mohs 6 to 7. ASTM C615 granite: not over 0.40 percent absorption, not under 2,560 kg/m3, 131 MPa compressive and 10.34 MPa modulus of rupture; about 2,700 kg/m3 in practice |
| Weight and Loading | About 54kg per square metre at 20mm and 81kg at 30mm. A 2800x1600x20mm slab is about 242kg, and about 111 slabs load to a 20ft at 26 to 27 tonnes |
| Caring for a Leather Face | Dust sits in the grain and comes out with a stiff brush, not a cloth. A sealed face takes more sealer per square metre than a polish |
| Applications | Cladding wall and floor applications, stairs, window sills, countertops, exterior paving, pool surrounds and interior flooring |
| Irregular and Curved Work | Irregular stairs are produced from your CAD drawing: a 1:1 template is printed for production and the finished pieces are assembled before packing to confirm they match |
| Packing | Face to face and foam faced in a seaworthy wooden crate or A-frame, edges and corners protected, steel banded, fumigated to ISPM-15, with photographs of the finished and loaded order |
| Quality Control | Block quality first, production managers following production quality, and finished products checked piece by piece; over 80% of products are sold to Europe |
| Minimum Order, Samples and Port | One bundle, with small trial orders accepted and mixed sizes consolidated. Free sample with freight paid by the buyer and refunded against the order; Port Xiamen, China |
Quality Standards
Quality Control & Inspection Standards
Block quality before the saw
Blocks are read for colour and for the evenness of the dark grey field, because a granite that drifts in tone is more visible on a wide slab than on a tile, and the block is graded before it is committed to a run.
Leather texture read at a low angle against the light
The face is walked past at a shallow angle under raking light, which is the only reliable way to find an uneven grain, a patch where the brush head dwelled and came out burnished, or a texture that is lighter at one end of the slab than the other.
Texture depth measured against the approved sample
The first slab of a run is signed off against a retained reference and the rest are read back to it, because texture depth is a process variable and a second run that is brushed one pass further reads as a different finish on the same wall.
Practical Applications
Exterior paving, pool decks and garden steps
The grainy face is chosen here for grip underfoot, and because a polished dark grey slab would read every splash and every wet footprint on a deck that is walked on wet.
Wall cladding and facades, interior and exterior
An Old G654 Granite Slab Leather Top is specified for vertical work where the matte surface cuts the glare a polished dark grey would throw across a large elevation.
Flooring in entrance halls, corridors and commercial interiors
A dark grey floor that hides dust, scuffs and water spots, in a finish that does not need the daily polish a dark polished floor would.
