Sentou M 400 Aluminium Spiral staircase

The iconic masterpiece, the M400 staircase, is much more than a functional element: it is a true aerial sculpture that seems to defy gravity.‎ Designed in 1966 by the visionary Roger Tallon, this staircase embodies elegance and modernity.‎ Initially designed for the CIFOM as part of a project exploring the applications of cast steel, the M400 staircase quickly achieved enormous success.‎ Initially made of steel, from 1968 it was made of cast aluminum by the Lacloche gallery, which offered it in three different diameters.‎ Since 1986, Sentou has perpetuated Roger Tallon's legacy by exclusively publishing and distributing the M400 models (diameter 110 cm) and the TH version.‎ Production is carried out using the original tools, in a French foundry, thus guaranteeing the quality and authenticity of these exceptional pieces.‎ The staircase consists of a central tube that houses a base plate and a stack of individual steps, ending with a landing step positioned at the level of the upper landing.‎ An aluminum sheath completes the set.‎ Dimensions: Step height 20 cm / total external diameter 1.‎10 m Version M400 = Die-cast aluminum steps with rubber pads / Mirror polished finish or lacquered in the RAL color of your choice Made in France The Sentou editions are not re-editions but the continuation of the production of the stairs following the same techniques and the same original tools: there is no difference between the first productions of the 60s and those of today.‎
