The spiral staircase has always been a means of saving space, providing access to lofts and roof decks without taking up precious floor space. Designed by Architect Alvaro Plugs for Italian manufacturer Sandrini Scale, the Etika metal spiral staircase makes this consistently functional form sculptural and artistic. Debuted in oxidized iron, Etika exhibits elegance, strength and industrial charm.

Etika. Designed by Alvaro Plugs for Sandrini Scale.

“The helix-shaped metal structure is formed by blending two spirals; one outside and one inside serving as a rigid support for the former.” A sequence of metal steps wind their way to the top, climbing the central structure and puncturing through its monolithic form. The individual stairs cantilever over the floor, connected only by a delicate metal rail that frames the design – composed from ascending double blades, a flat handrail and 2 horizontal reinforcing rods. The overall effect is that of strength and weightlessness – the central structure grounds the staircase (serving as its core with a diameter of 80cm) while the metal steps appear to float.

A strong base of iron, stainless steel, bronze or Corten steel is finished with oxidized or painted iron, polished and brushed stainless steel, bronze, copper, brass, even the luxurious look of gold leaf and silver leaf. The monolithic metal has a thickness of 10 mm with veils of support submitting than exude to see from the central structure. The structure in metal was supplied to the crude one and therefore polished (no veneer).
