A right-turning spiral staircase is climbed from the bottom to the top at a clockwise direction. When you climb the stairs, the centre spindle is on your right and you can hold on to the banister with your left hand.
All Minka spiral staircases can be installed in both left- and right-turning positions.
As the name already suggests, space-saving staircases are mostly used in places where there is not so much space. Minka’s space-saving staircases are so-called central stringer staircases, which are particularly flexible in their construction. They can be installed straight and in many cases also slightly turned to the left or right. Moreover, Minka has some quarter-turned space-saving staircases in its range.
Minka spiral staircases are supplied with a triangula platform as standard. This is mounted on the same level as the floor of the upper storey. This allows you to exit comfortably on the upper floor.
Our space-saving staircases do usually not have a platform. Only the Quatro Turn quarter-spiral staircase is supplied with a platform, which is necessary for the 90-degree turn.
Austrian norms are known by the abbreviated designation ÖNORM. They describe certain standards that are to be complied with in various fields – such as construction. The norms developed by Austrian Standards are often also recognised throughout Europe, which can be seen from the combination of letters EN (e. g. ÖNORM EN 1363).
All staircases by Minka belong to the category “non-essential staircase”. Such stairs are often used to reach an attic or to have a second access to a floor or gallery.
A central stringer staircase is a special type of space-saving staircase in which the steps are mounted on support elements along the centre line of the staircase. The support elements are made of metal and are adjustable in height, which means that central stringer stairs are considered very flexible and space-saving. Central stringer staircases are sometimes also called mono-stringer staircases.
With a left-turning spiral staircase, you go up the steps in an anti-clockwise direction. With this variant, the centre pillar is on your left hand when going up and the banister is on your right hand.
All Minka spiral staircases can be installed in both left- and right-turning versions.
The term clear room height refers to the distance from the upper edge of the floor to the lower edge of the ceiling. The clear room height is particularly relevant when purchasing attic stairs.
Height extensions are available as an optional extra for most of our space-saving staircases and spiral staircases. You need a height extension if you need to reach a room height that is higher than the standard dimension. When you order a height extension, you get an extra step as well as the extra material for the extended railing.
Please note that you may not install more than a maximum of two height extension elements per staircase. Stability and safety when climbing stairs can no longer be guaranteed if more than two additional steps are installed.
The handrail is the upper part of the railing that you can hold on to with your hand. The handrails of the Minka system staircases are either made of solid wood or high-quality plastic (PVC).
