Every block one of a kind
One catalogue entry is one quarry block. Slabs are numbered in cutting order, so consecutive slabs read almost identically — and bookmatch.
Porcelain — Atlas Plan
The engineered consistency of porcelain
Large-format Italian porcelain in three formats — scratch, heat, stain & UV resistant, no sealing, indoor & outdoor. Develli is an Atlas Plan partner.
