Sintered Stone for Architects, Designers & Contractors
Specification support for teams that need the material to match a drawing: formats, thickness, joint planning, bookmatch direction and project quantities.
Specification data
Thickness and typical use: 6 mm wall panels and cabinet fronts; 9 mm interior surfaces; 12 mm and 15 mm countertops, islands and table tops; 20 mm heavy duty, produced in 1220 × 2700 mm. Slab formats: 900 × 2700, 1200 × 2700, 1200 × 2400 and 1600 × 3200 mm. Performance: heat resistance to 1,200°C, Mohs 6–7 hardness, water absorption below 0.2%, stain resistance Grade 5, UV stable for exterior exposure on selected surfaces, food-contact safe.
Joint and pattern planning
Send the drawing and the team will review vein direction against the layout, identify where a bookmatch pair should land, and confirm the joint tolerance (1 cm on bookmatch pairs) before cutting. This is the step that decides whether a large island reads as one surface or as three.
Project supply
Quantities are allocated against the drawing: slab count, cutting plan, edge profile and delivery sequence. For hospitality, retail and residential developments, the material is scheduled to the installation programme rather than supplied as a single drop.
What we need from you
Drawings, application and area, thickness, finish, colour direction, site location and required dates. With those, availability and pricing can be confirmed against the actual slab rather than an indicative rate.
Site support
Fabrication is cut to drawing. Fixing details, substrate requirements and installation sequence are confirmed with your installer before delivery, so the material arrives in the order it is needed.
