A spiral staircase is used where due to construction
reasons it is impossible to design a classical straight staircase
or where aesthetics is important at the place of installation of
the staircase. The spiral staircase consists of a central tube,
to which single segment-shaped stairs are gradually attached and
anchored. In addition to the segment stairs, the spiral staircase
is also delivered with the starting and ending platforms. The spiral
staircase can be zinc-dipped according to EN ISO 1461 standards
or otherwise surface treated. After zinc-plating of all components,
the spiral staircase is assembled and only after this released for
sipping. |
