Pin staircases are staircases of modern style with a combination of stainless steel and solid wood. On the side of the wall there is a staircase anchored to stainless steel spikes in the wall or it is mortiseed into a stringer (sidewall). On the inside of the staircase, the individual scales are connected by stainless spacers with a diameter of 50mm. Spiral staircases can also be suspended from the ceiling.
These staircases are made open, without risers.
The railing is mostly stainless with a wooden handrail or with stainless steel ropes and also a very popular glass railing.
