Grit Profile

The grit incorporated into GritPlate is a Fused-Alumina or Quartz that is available in the following grades:  Ultra-Fine (Barefoot), Fine, Medium, Coarse and Ultra-Coarse.

Cleaning / Maintenance and Life Expectancy

GritPlate is a tough material that can withstand “aggressive” cleaning such as the use of stiff brushes and power-washers as detailed in our guide to the Cleaning & Maintenance of GritPlate.

With little maintenance GritPlate will retain its active anti-slip properties for 15 – 20 years depending on application.  In addition, due to the high level UV-protective coating the sheet will not suffer from significant colour fade for at least 15 years.

After researching many forms of grit, Smyth Composites elected to use either Fused Alumina or Quartz due to its superior qualities and suitability for the anti-slip applications. Other types such as Bauxite are available by special order. The Fused Alumina and Quartz are available in a variety of grades:

Ultra-Fine (Barefoot), Fine, Medium, Coarse, Ultra-Coarse

Panel Size and Thickness

Panels can be manufactured to any length but with a width restriction of 1500mm. Standard product range can be manufactured to literally any thickness from 2mm upward. As this is a handmade product, containing various raw materials, tolerances apply to both size and thickness which may vary depending on the specifications ordered.  Occasionally we can accommodate “oversized specials” – please contact us for details.
