Timber Treatment:
To finish the wooden parts, Fontanot uses a unique painting process using water-based UV products that are at the leading edge of paint technology in terms of performance and consideration for the environment and health. The result is an ecological, non-toxic material, natural to the touch and with a quality finish resistant to abrasion and the scars of time.

Steel Components:
Painted steel, polished AISI 304 stainless steel or satin nickel-plated steel are used for the structural parts of the Genius range, depending on the staircase model. The painted steel is available in five standard options and undergoes a particular epoxy powder coating process with drying at high temperatures. This treatment guarantees a superior performance in colour uniformity and resistance to abrasion.


We recommend the use of a damp cloth for the timber elements and polish off with a dry cloth. We advise against the use of products which contain siliconic oils for use in the furniture industry (like dust eating products) because they create a patina on the treads that would make them slippery).

The Genius T staircases are designed and produced in Italy where the building regulations are different from the UK. We would be happy to advise you on UK Building Regulations and how they might affect your choices. We always strongly advise that you also discuss your project with your local Building Control Department before committing to purchase. You will find information on the Building Control Regulations and the British Standard for Spiral Staircase on our Knowledge Centre here
