Nero Marquina Black Marble Stair Steps For Hotel Projects
A marble staircase (or stair) represents elegance, good taste, ease of cleaning, practicality, quality and a unique beauty that lasts over time.
All Italian marbles can be used inside, usually with polished or honed processing, while for the outside we recommend using our Beige Alpi or Rosso Asiago (or in any case marbles suitable for the outside) possibly with non-slip, bush-hammered processing, brushed or rolled that allow qualities of resistance to frost and corrosion due to the climate of any place. Materials guaranteed for quality and resistance by CE certificates.
According to your personal tastes, the choice of covering a marble staircase allows you to have great value and elegance in your home. Thanks to the wide variety of marbles available, it is possible to choose any color that can be a white, beige or black, brown, green marble staircase.
The light marble most used marble in a home are Bianco Carrara, Calacatta, Statuario, Arabescato, Travertino, Botticino and Bianco Perlino. As for the dark and colored marbles, the most used inside are Nero Marquina, Emperador, Rosso Verona (Rosso Asiago), Verde Alpi, Verde Guatemala, Sahara Noir and Grigio Carnico.
In addition to the choice of the various types of materials and colors, a detail to take into consideration is the structure of the edges of the treads, risers, the handrail and the railing.
Until a few years ago, requests for indoor staircases were almost entirely with more important and expensive processes than today, such as edge finishes of the full bullnose or half-bullnose tread.
With reference to today's global market, however, the requests for marble stairs are mostly requested with simple and minimal workmanship, straight edge finishes and with Roman model laying, that is, with riser and tread without protrusion.
The Treads measure approximately 100 cm to 150 cm in length and approximately 30 to 35 cm wide.
The Risers measure a length from about 100 cm to 150 cm and a height from about 14 to 18 cm.
