Research and Innovation
PATENTS

Staircases are a very young product that will improve in the coming years in ways that were unthinkable until recently. The passion for research has led d'Opera to develop those margins for improvement which have resulted in innovations capable of disrupting the entire industry.

To date, d'Opera has filed 12 patents – a part of the identity that makes its products recognisable and special.

E20 SYSTEM

Among the most recent patents, the E20 system is an ingenious design of modular resin elements which are repeated to form the backbone of the staircase on which to "innervate" the sequence of steps.
This module can grow indefinitely, to adjust to any space and height, measure and difference in level.
E20 is a flexible system with an organic course; just like a natural form - the spiral of a shell or the helix of DNA - it is flexible in form and use.
