SG Signature Porcelain

SG Signature Porcelain is the latest addition to the Stone Group surface portfolio. It is made for projects where the finish needs to read cleanly, and performance needs to stay consistent over time.

Every slab is produced to meet international quality standards for large-format manufacturing. The range is manufactured using Italian SACMI CONTINUA+ compaction technology, supported by systematic inkjet printing, pneumatic glazing, and a Jumper Klin firing system.

The material is supplied in a 1600 x 3200 x 12mm compact surface format. It is formed from natural minerals (including quartz, feldspar, and oxides), then compressed under high pressure and sintered at 1200–1400°C to create a dense, stable slab. With a Mohs hardness of 7–8 (similar to granite) and water absorption of < 0.1%, it is well suited to demanding residential and commercial applications.
