G654 Granite Kerbstone: Color & Texture
G654 Granite Kerbstone — G654 Sesame Grey granite — features a dark grey, salt-and-pepper speckled surface that reads as neutral grey from a distance. The fine-to-medium grain gives it an even, businesslike texture that suits both modern and traditional settings. Under a flamed finish the surface develops a light tooth that reflects less light and grips more; polished G654 shows a deep, mirror-like grey. The same stone accepts bush-hammered, sandblasted, and honed finishes, which is why it appears across paving, cladding, stairs, and monuments.
Key Takeaways
- G654 granite (Sesame Grey): density 2.63–2.75 g/cm³, water absorption 0.10–0.36% (ASTM C97), compressive strength 174–218 MPa (ASTM C170) — cross-referenced supplier data
- Mohs hardness 6.5–6.8 — one of the most durable granites for outdoor use; flamed finish provides high slip resistance for paving
- Road edging, driveway borders, and municipal paving is a core application — G654 is the world's most specified grey granite for exterior work
- Phoenix Power Stone — 108,000 sqft factory in Shandong, China, 24+ years of export experience, FOB Qingdao
G654 Granite Kerbstone Technical Properties
G654 Granite Kerbstone from our Shandong facility tests at 2.63–2.75 g/cm³ density, 0.10–0.36% water absorption per ASTM C97, and 174–218 MPa compressive strength per ASTM C170 — values cross-referenced across StoneContact, BS Granite, and Chinese supplier data sheets. Mohs hardness of 6.5–6.8 means this stone resists scratching from grit and foot traffic. With absorption below 0.3% on most blocks, G654 survives freeze-thaw cycling without spalling — the reason it is the default choice for exterior paving in cold climates.
G654 Granite Kerbstone Outdoor Paving & Road edging, driveway borders, and municipal paving
G654 granite is the workhorse of outdoor paving. In road edging, driveway borders, and municipal paving, the flamed finish creates a rough surface that stays grippy in rain, snow, and ice. Standard paver sizes run from 300×300×30mm to 600×600×50mm, with kerbs and steps cut to specification. The stone's dark grey tone hides dirt between cleanings and does not glare in direct sun the way light granites do. For driveways, specify 50mm thickness; for pedestrian walkways, 30mm is standard.
G654 Granite Kerbstone Building & Construction Use
Beyond paving, G654 granite is specified for building cladding, stairs, curbing, and monument work. Its consistent color across batches makes it reliable for large commercial projects where color drift would be visible. Polished G654 serves interior flooring and countertops in commercial settings where granite durability is required at a working price. Our factory cuts, calibrates, and finishes to client drawings — including radius kerbs, custom chamfers, and drilled anchor holes for cladding systems.
