Product Description

Okite Grigio Chiaro is a quartz stone with a light grey background and very fine grains, that brings the classic look of granite or slate to kitchens, bathrooms, flooring and walls through a product with superior performance that is highly resistant to staining, etching, scratching and it is also highly resistant to heat.

Okite Grigio Chiaro quartz is suitable for applications in worktops, flooring, cladding and furniture delivering a versatile quartz stone that works well with any architectural feature, ensuring the user has a unique product with everything required to design unique spaces.

Due to its fundamental mechanical strength, Okite works perfectly in commercial spaces which include offices, restaurants and bars, hotels and bakeries; with a surface that will resist the most demanding tasks, bringing life into interior areas.

Okite Grigio Chiaro surfaces are the result of a skilful blend combination of approximately 93% pure quartz and polyester resins with pigments in a wide array of colours and finishes. Slab formats with dimensions of 3090x1440mm and thicknesses of 13mm, 20mm and 30mm are available to guarantee quartz surfaces for any type of interior application.

Seieffe, who makes Okite, guarantees that their products are non-porous and will never require sealing, with a durability of over 5 times more than natural granite. Further benefits of this stone include its remarkable ease of maintenance and the intrinsic kindness for the environment during its production stages by using recyclable materials including quartz and glass plus the efficient industrial processes to which each slab is subjected.

Seieffe has been producing quality quartz in the South of Italy for over 50 years, gaining experience and innovative skills to design agglomerate surfaces with two production lines located near the Amalfi Coast and has a distribution network present on over 90 countries and over 10.0000 approved suppliers worldwide.

    Additional Information

    Additional Information

  • Material considerations:
  • • 30mm Material is required for hot & cold food service applications.
  • • Loads must not exceed OKITE’s capacity. Please refer to most recent OKITE’s Data Sheet
  • • Provide adequate support directly underneath any external load and do not use OKITE®
  • • to transfer bending and/or shear loads from external equipment or apparatus to supporting structures
  • • All inside corners must have a minimum radius of 2,5mm
  • • Wider (at least 3mm) soft seams are recommended
  • • Steps should be taken to insulate OKITE from heated food service equipment (i.e. heated bins). A minimum of two layers of Nomex® (or equal) insulating tape with a minimum thickness of 2,8mm/layer and a minimum weight of 9.5 oz./yd2/layer is recommended
  • • Allow a clearance of 3mm between OKITE and any adjacent walls, cabinets or other constraint. For a drop edge also leave at least 3mm behind the dropped edge and the casework to allow for expansion and contraction from temperatures variation
  • • The design must accommodate expansion and contraction to minimize the build-up of mechanical and thermal stress. OKITE coefficient of thermal expansion is 5.9x10-6in/in/°F, as determined
  • • by independent testing laboratories using the standards of ASTM
  • E-228.
