Tetra

polygon structured finish

TETRA DARK GREY 148mm in commercial kitchen
Technical sheet

The pyramid shapes on the surface profile means that Tetra has excellent slip resistant qualities for all areas of bare foot and shod foot traffic. It has good volume displacement properties (V4) as the profile has been designed to pierce surface debris – make it a great choice for preparation areas where heavy soiling is likely.

Also use it for:

  • Changing rooms and shower areas in swimming pools and health spas
  • Retail and light industrial unit
  • Commercial kitchens and food preparation areas
  • External walkways

See Luna, Pinhead, Multidisc and Textured for more tiles suitable for wet areas (shod and barefoot)
