Options for standard spiral staircase

We use standard components to achieve a rational production which results in both good pricing and continuous high building quality. The stairs are of course customized specifically for your facility and your demands. 

The components that a Eurostair spiral staircase consists of are available in different designs. You can read more about the options for each component under each category below. 

Step surfaces

There are different step surfaces to choose between. Outdoors gratings are often used as the step surface since it contributes to non slip surfaces and does not collect snow and rain on the surface. Further, it does not interfere the overall visual impression of the building since the stair easily blends into the background. 

For a spiral staircase inside one can advantageously choose a surface of wooden or rug for a softer and more quiet stair. 


33x50 mm is our standard step made of press welded grating and is suitable for most applications where you want good throughput. Snow falls easily through and it gives exellent slip protection.


The step surface is made of press locked grating with tighter mesh width, 33x11mm. The press locked grating has flat steel in both directions.


The tear plate is completely dense with a tear pattern which gives moderate slip protection. The tear plate is easy to keep clean from dirt and water.


A step made of a steel plate adjusted to the thickness of carpet, wood or tile.


Step frame as other models with cross stabilizers to anchor the wooden step from the underside. On the picture, you see a step of oak. Contact us for more information about what sort of woods we can offer.


Step frame as other models with cross stabilizers to anchor the wooden step from the underside. On the picture, you see a step of walnut. Contact us for more information about what sort of woods we can offer.


In our standard range there are six standard railings. The staircase poles consists of
U-profile 30x32x30 mm. You choose the railing model that is most suitable for the environment the staircase should be used in. For a spiral staircase to be fully child safe no opening can be larger than 100 mm. 


Our industrial railing consists of U-profiles with the measurements 30x32x30 mm. They have an important function for the stability of the staircase since they are attached in both the step and the handrail. The poles are easily assembled from the inside of the staircase.


The child safe railing consists of poles in U-profile 30x32x30 mm where arcs has been welded on both sides of the pole to give a maximum opening of 100 mm. This is the maximum horizontal openingin the staircase railing. With these child safe poles the staircase can be used in all types of environments. The child safe poles can easely be assembled, as the industrial poles, from the inside of the staircase.


The railing consists of U-profile poles of 30x32x30 mm to make the staircase child safe. The poles have a horizontal opening of 100 mm. The poles are assembled from the inside of the staircase.


Knee lists are used with the purpose to improve a standard industrial railing. The knee list is made of flat iron which are attached to the industrial railing. This railing model does not count as a child safe railing since the openings in the staircase exceeds 100 mm.


Same as railing with one knee list with the difference that this railing has two knee lists attached to the industrial railing. These types of railings are primarily used to improve a standard industrial railing. Just as the railing with one knee list the knee lists are made of flat iron.


There are two different types of platforms in a spiral staircase. There are top landing  platforms that ends the staircase on the top and resting platforms between different sections of the staircase. You can choose the surface of both these platforms.
The platform railing is like the rest of the staircase made of industrial or child safe designs. Where there are big platforms the platform/platforms should be assembled onto the facade with consoles before the center tube are assembled but all that are extensively described in the assembly instruction that follows the staircase. 

Of course, the staircase is built specifically with meashurments for your building and with the goal to give you the best direction and flow in the stair. 


Landing platform is the platform where the staircase connects to a facade. Our platforms is available in several different designs and always customized to suit your start point and landing points of the spiralstaircase.


Landings can also exists between different staircase sections if the staircase have several. Higher floor levelsmight require can be complemented with landings to get a space to meet or to rest on.


The connection step is used instead of an top platform where you want to connect to an existing floor level. The connection step is elevated at the back edge to be able to attach to the floor. It is important to know the thickness of the floor, so it is space enough to attach the connection step.


The handrail in a Eurostair spiral staircase is manufactured with modern 3 D bending machines. No sharp interruptions or protruding screws can be found on the Eurostair handrail. The design is carefully thought out for best function. 

The handrail consists of handrail sections that range over 3 - 5 steps and are assembled to the railing poles. To connect the handrails, we use a unique and easy to assemble sleeve, on the underside of the handrail, which gives a stable and simple handrail sheeting with barely notable joints. Due to the sheeting you can follow the handrail with the hand without having to let go when you walk the staircase. 

The lower part of the handrail also works as a support to the grounding. At the bottom of the handrail there are an adjustable foot to anchor to the ground or floor after adjustment. 


The handrailing is made of steel tube with diameter 42,2 mm and wall thickness 3 mm. It can be delivered in galvanized, powder coated or galvanized and powder coated finish. The staircase pole is a U-profile with measurement 30x32x30 mm, and the handrail is assembled to the stair pole with M6 bolts/nuts.


The surface treatment of the staircase is determined by whether the staircase should be placed indoors or outdoors. To get the best anti-corrosion protection we always work with a two-step process in terms of powder coating. First a layer of zinc primer to get an great protection for rust and better surface finish and then we add a layer of RAL powder coating.


For spiral staircases with large radius a handrail on the center tube can give extra comfort when walking in the staircase. Since the step depth closest to the center tube is at it smallest it can also be a additional safety to have rails on the centertube.


The inner handrail gives extra support for example children and is placed inside the railing poles at the height of 900 mm. The handrail is made of seamless steel tube 42,4 mm with a thickness of 3 mm.


Inner handrail in wood can be delivered to all staircase railings and platform railings. The handrail is made of massive wood and has the diameter 50 mm. Contact us if you want to know more about what types of wood we can supply.


Inner handrail in walnut which can be delivered to all staircase railings and platform railings. The handrail is made of massive wood with a diameter of 50 mm. Inner handrail in wood is available in different sorts of wood. Contact us if you want to know more about sort of woods.

Protective cages

In environments where children are present or a risk for unwanted passage exists you can add a protective cage to prevent access to the spiral staircase. The cages can look different and have different height. As a standard we produce the cage as a rounded quarter cage in grating, but it is also possible to have a ground connected cage which is placed outside the staircase. 


The quarter cage is our standard cage and is assembled directly on the staircase construction and follows the staircase a quarter turn. The quarter cage consists of grating sections and a doorframe with a door in grating. The grating sections is assembled directly on the staircase poles and the door is prepared to be supplemented with an ASSA locking cylinder.


A detached ground connected cage is placed on fundaments outside the staircase construction. As standard the cage has diameter 1300 mm and height 3000 mm. Sections to add is available to reach a height of 4500mm. As special the cage can also be manufactured in a square shape.

Surface treatment

Galvanization is a very effective method to protect a spiral staircase from corrosion and has a grey color tone which blends into most environments in a naturally way. It is also possible to powder coat the galvanized spiral staircase. A duplex treatment gives an exceptional corrosion protection since the underlying zinc prevents corrosion even if the layer of color is damaged. We galvanize according to EN1461.


Recommended for products both indoors and outdoors. The galvanization is the best surface treatment to protect steel from corrosion and has a grey color tone which makes it blend in naturally in most environments. The steel is dipped in liquid very hot zinc which binds chemically with the steel and results in a strong durable surface. As standard the spiral staircase for outside is delivered galvanized according to EN 1461.  

Powder coating 

Solely powder coating as surface treatment is suitable for products that should be placed indoors. Powder coating is a durable, protective, and environmentally friendly surface treatment method. Compared to the traditional paint which contains a lot of solvents the powder coating is much have much fewer negative effects on the environment.  The method can be used to paint many different materials. As color surface the powder coating is enduring and can handle both mechanical tensions and strong chemicals. The application is made completely dry and electronically which facilitates an even distribution of the color particles and it makes it easier to access hidden angles. Use the powder coating on galvanization for best protection.   We powder coat in RAL color with gloss ranges for both outside and inside.  

Duplex treatment

Recommended for products outdoors. Duplex treatment, i.e. both galvanization and powder coating give a very good corrosion protection since the underlying zinc prevents corrosion even if the color layer is damaged in example transport or assembly. A duplex treatment gives a surface treatment with low lifetime cost. A bit more expensive initially but the cost for maintenance and replacement is substantially lower. 

Our standard colors

Eurostair offers a color and quality color and quality stable colorsystem by using the standard RAL Classic®. We have chosen 18 colors that is Eurostairs standard colors to match the standard colors for the bransch. As an addition we can poder coat in optional RAL-color that you wish for, there are 215 different colors to chose between.
