The anti-slip characteristics of rice grained sheets are certified according to DIN 51130
The dimensional tolerances of the rice grain comply with ASTM A793 Pattern B
Special dimension and tolerance requirements will be evaluated in each case

DECORATED AND MICRO-DECORATED FINISHES

Perfection in all its details.

The decorated and micro-decorated finishes are obtained through the use of specially decorated rollers, during the cold-rolling process; subsequently the material is subjected to polished annealing heat treatment.

The finishes may be customised on demand
