SILVER GREY GRANITE (FLAMED SURFACE)
FLOORING TILES, OUTDOOR PAVERS & COPING
Silver Grey is exactly as the name suggests - predominantly a silver to mid-grey. However, Granite has many different geological components (eg mica, feldspar etc) and they all contribute to the overall colour outcome. In summary though, this product is a light, fresh, speckled grey stone with a grippy, flamed finish. Silver Grey Granite is ideal for use as an outdoor surface. We are confident that it has the necessary durability for any outdoor surface because it is dense and very hard; its light grey colour is very popular; it has a surface that is safe so that the risk of slipping when wet, is low; and finally, it is very affordable.
Tiles, flamed - 800x400x15mm
Pavers, flamed - 600x400x30mm
Bullnose pencil edge flamed - 800x400x15/30mm
Bullnose pencil edge coping, flamed - 600x400x30mm
the thinner tiles (15mm) are recommended for use on concrete substrates and the 30mm pavers on roadbase. the thicker pavers are also suitable for use on concrete but they are only really needed for heavy traffic e.g. driveways.
NB. When photographed, the true colour of granite is very hard to replicate. Therefore, we suggest popping into our warehouse and seeing the stone in person rather than relying only on the above images.
INDICATIVE TEST RESULTS
Slip resistance (AS/NZS 4586-2004) (honed) - pending
Slip resistance (AS/NZS 4586-2004) (tumbled) - pending
Flexural strength (ASTM C880) (dried) - 17.0 MPa
Flexural strength (ASTM C880) (wet) - 16.1 MPa
Density (ASTM C97-02) - 2793 kg/m3
Water absorption (ASTM 616) by weight - 0.16%
Resistance to salt attack weight loss (AS/NZS 4456.10) - 0.19%
NB The benchmarks for use of stone around salt water pools is 0.1% weight loss or less with a minimum slip resistance classification of W.
Architects - AS HB197 (see below) may be used to approximate Oil Ramp test R values - there is no conversion table as the tests are vastly different. On this basis, V (on the more relevant & less costly wet pendulum test) is closely aligned with R11 and X with R10.
IDEAL FOR USE AROUND SALTWATER POOLS
Granite is one of the safest stone types to use around saltwater pools or for outdoor paving use in maritime environments. This is a product that has a non-slip surface and wonderful density coupled with low water absorption rates and high durability.
