FAQ

Spiral stairs are used for escape routes, industrial stairs and indoor stairs to accommodate level differences between different floors. Most often, spiral staircases for escape are mounted on the outside of the property. Spiral staircases in industry are used both inside and outside and manage walkways and level differences between different floors. Premium stairs and Concept stairs usually deal with level differences indoors and thus become central parts in the rooms. We call the Concept staircase a designed piece of furniture.

The requirements are always based on the building's class definition. The building class determines the requirements for bearing capacity which are governed by national annexes from Eurocodes. Railing heights may vary for different building classes. The design of the stairs is governed by the function the stairs must have. Therefore, doorways can be controlling for stair radii in an evacuation situation. The clearance height in the flight of stairs and under the flight of stairs is important for how the stairs must be designed geometrically. Step height and step depth tell what angle the staircase will have. The step depth tells you how good the spiral staircase will be to walk in. Be especially careful when moving down the stairs. The foot movement means that with small step depths you will only use the heel of the foot to walk on. We always control the start and end of the stairwell with angles on the plan. As a result, we are able to maintain a good step depth on our spiral staircases.

A one-story spiral staircase is today built with a central tube where the plane is screwed to the tube and then soldered and fixed to the facade. The steps are then screwed onto the center tube. Railing posts are then attached to the outside of the step and thus bind the steps together into a truss construction with stability and load-bearing capacity. The railing posts then carry the railing filling with sheet metal or braces. Finally, a supervisor in a suitable material is mounted on the railing posts. Any step surfaces are finally mounted on (In the case of wooden surfaces). Modern stairs are often built in high-strength steel materials that provide lower weights and thus lower environmental impact in all processes from production, surface treatment, transport. Our fitters testify to the market's easiest and fastest assembly, which is done with only two different simple fixed keys.

When we work with our stairs, we always see a staircase as a whole. In Scandinavia, function is often the most important ingredient, while in Europe design is often seen as more important. We want to do both with the more exclusive stairs. Function through solid construction and design through cleverly thought-out details. Our goal with spiral stairs is to keep the nice round shape and let it go again on the outside of the steps. In this way, we get a prominent roundness and no angular ones that are often seen on the market. Our 3D bent round and fine supervisor is one such example.

Yes, normally you can assemble the staircase yourself. You do not need any special knowledge or special tools. The assembly instruction you get from us. Please look at the assembly instruction here on the website.

The short answer is that it is from the finished floor of the lower level to the finished floor of the next joist. The slightly longer answer provides in-depth knowledge on this subject: To begin with, it depends on whether it is one or more floors. If it's a single storey it's easier. Then you measure the height from the finished surface of the first joist, add the thickness of any floor covering. Then you have a zero point. Then you measure the height up to the finished surface of the next joist and add the thickness of any floor covering. This is the finished height of the stairs. If the staircase consists of several storeys in height, the height is specified in the same way with reference from the top of the spiral staircase to the second floor of the spiral staircase, the second floor to the third floor and so on. If flooring is to be laid, this must also be taken into account. When the stairs are delivered with finished Eurostair flooring, this thickness does not need to be added, but you still need to control and carefully observe the effect of any floor coverings on the finished height of the stairs.

The details are everything. For example, it is important that the hand can run along the guide without getting caught in attachments or sharp edges. The steps must be safe and non-slip to set foot on. The details are often what separate different manufacturers' products. The knowledge about an acceptable solution for us at Eurostair is not only in the technical solution but also in the feeling the design gives to the person who has to look at the product day after day. Our development team is constantly working to expand our product range to meet tomorrow's customers and demand. We often bring in special solutions for our customers in combination with the standard product. Our customers really appreciate it; a little identity of your own always warms. More rational production, more use of modern steel materials, design improvements, adaptations for specific controlled needs, etc. is constantly on the agenda of the development team.

Spiral staircases are an ancient craft. During the last century, the stairs were built to completely different requirements and specifications and in ordinary "bonn iron". Eurocodes and safety factors are demanding and we therefore work with suitable materials that can meet these requirements. With modern high-strength steel and structurally optimized design, we have taken stair construction and production to a new level. The fact that with our smart material choices we also get environmental friendliness at the same time makes the choice easy.

Yes, you can buy our staircase with many different types of steps, including wooden steps. For example we offer oak, ash, walnut. We produce steps with all kinds of wood.

Yes, you can. Handrailing and steps can be provided with lightning, preferably with RGB led for the coloration. We work with different LED-light sources which gives a discrete assembly and a thrilling lightning. Contact us for finding out the possibilities for your project.

Yes, you can use our Standard and Premium stairs both indoors and outdoors. The exclusive staircase is a design staircase intended for indoor use only.

There are three different models of spiral staircases. A Standard model primarily used for industrial and evacuation purposes. Our Premium model is intended primarily for indoor use but can also be used outdoors. Our third model Exklusiv is a staircase model that is a customized design staircase for indoor use.

A childsafe railing in a staircase should be minimum 900 mm high and not have any vertical openings that are bigger than 100 mm. Also, keep in mind that the railing should not consist of any horizontal parts that entails climbing. If you want a fully childsafe staircase you should not have more than 100 mm opening between the steps.

The spiral staircase can be built with step heights from 150 to 200 mm. The step height, together with the step depth, helps to determine the stair angle. The free height of the stairs (min 2000 mm) can be difficult to maintain if the step height is set low.

To begin with, is it important which way to go on the stairs, down or up, or both? If it is a pure escape staircase, no space is needed to be able to stand and open the door from the outside. Then the only need is a platform that provides a safe first step outside the door before you step further down the stairs. However, if the stairs are to be used in both directions, it is important that the platform gives you room to stand when you have to open the door from the outside, so that you do not have to stand down on the stairs. In other words, a platform for a staircase you are going up requires a larger platform than a pure escape staircase.

In general, it can be said that a spiral staircase should not be used as a primary route in a public environment. This as it can be cramped and awkward to meet someone else on the stairs. In those cases, it is better to choose a straight staircase rather than a spiral staircase. A spiral staircase is instead best suited as an alternative route or when a smaller number of people use it as a travel route. However, a spiral staircase saves space and takes up less floor space than a straight staircase, which means that it can be advantageous to use a spiral staircase if space is limited.

There are three different models of spiral staircases. A Standard model that is primarily used for outdoor industrial use. Our Premium model is intended primarily for indoor use. Our third model Exklusiv is a staircase model that is a 99% customized design staircase for indoor use.

The Eurostairs model Standard is built from standard components and the craftsmanship is limited to details and dimensional adaptations of planes and fixings. The stairs are manufactured in volume industrial production with a high degree of automation. The stairs are normally delivered in a galvanized version, but can also be powder-coated or duplex-treated. The price is low.

The Eurostairs model Premium is partly manufactured from standard components from stock, but there is also solid craftsmanship production of railing details and platforms. The surface treatment is usually a powder coating with zinc primer followed by another layer of powder coating. The price is higher.

Eurostairs' exclusive Concept spiral staircase is a product that is manufactured piece by piece according to the principles of craftsmanship. The choices are enormous and the demands on design and quality are high. Choice of materials, details and identity characterize the questions from our customers regarding our exclusive staircase.

We offer a wide range of standard models. In industry, you want simple safe railings, while public environments and homes must be childproof. We have railings for all situations. All our railings can be painted in one of our 18 standard colors or optional if the project so requires. The guide can be made of steel or wood. We solve all railing types and situations.

Yes, in some applications it is desirable to have a supervisor both on the inside and outside of the stairs. Then we can deliver stairs with guides that follow the center pipe at the center of the stairs.

Yes, it works perfectly in our Premium and Concept stairs. We work with various LED light sources that provide very discreet and exciting lighting. It can be lighting in supervisors or that illuminates the step. Contact us to find out what opportunities are available for your particular project.

Yes, you can get that in both the Premium and Concept levels. It is often suitable for both appearance and safety. We work with various LED light sources that provide very discreet and exciting lighting. Contact us to find out what opportunities are available for your particular project.

It is slightly different depending on which of our staircase models you are looking at. We offer the standard stairs in radii from 700 to 1200 mm. We have the premium stairs in radii from 900 to 1400 mm. The concept ladder is a 99% customized product and is offered in radii from 1000 all the way up to 1500 mm. We can offer other widths on request, but since a spiral staircase is a complex product, please contact us and we will help you implement your idea.

Our stairs are designed for extreme conditions. By using high-strength steel, we can further increase the possibilities for high-demand use. Contact us and our sales and design team will help you.

Our stairs can be built very high. For example, we have delivered very high external stairs to the Strängnäs cogeneration plant. One key is that we use high strength steel. This means that while the steel is extremely strong, we get lower weights to handle when the stairs grow in height.

We have the choices of hot-dip galvanizing, powder coating or Duplex treatment. Duplex treatment is both hot-dip galvanizing and powder coating. Outdoor stairs and stairs in exposed indoor environments must always be hot-dip galvanized. A painted outdoor staircase receives what we call Duplex treatment. In most cases, indoor stairs can only be powder coated.

We have 18 standard colors in the RAL scale. In addition to that, we can paint in any color you wish, contact us for more information. All painting of our products takes place through powder coating, a qualitative and environmentally superior painting system.

Yes, it is possible to use wooden steps in all three types of spiral staircases. We can supply most types of wood from pine to walnut, welcome to contact us.

Yes, our model spiral staircase Exklusiv is developed for design and exclusive environments with high demands on appearance and form. It is a staircase model that is a 99% customized design staircase for indoor use. We can manufacture it with a diameter of up to three metres! Then it becomes a sweeping and beautiful staircase in a home environment, office, shop or similar environments with very high demands on aesthetics.

Yes, our straight stairs are customized and fit both indoors and outdoors.

The spiral staircase can be built with step heights from 150 to 200 mm. The step height, together with the step depth, is what determines the stair angle.

With a step height of a maximum of 200 mm and child-proof handrail models, the stairs are child-proof. The important thing for a staircase to be classified as child-proof is that there are no vertical or horizontal openings larger than 100 mm.

Yes, it works perfectly in our Premium and Concept stairs. We work with various LED light sources that provide very discreet and exciting lighting. It can be lighting in supervisors or that illuminates the step. Contact us to find out what opportunities are available for your particular project.

Our straight stairs are built entirely to order and then you as the customer choose the width and we solve the construction and production. In general, it can be said that less than 700 mm is not suitable. A step width of 1100 mm makes a good staircase, but keep in mind that free width is lost because of the handrails, approx. 100 mm per side. If you are to be able to meet on the stairs, you need to have a step width of 14-1500 mm.

Of course! Please see our assembly instructions for the product you want. You will find these under "Documentation" at the top of our website.

Our stairs are always delivered ready for assembly. Everything is neatly packed in white boxes and the center tube is transport wrapped to avoid damage during delivery. All fittings, bolts and other fasteners are delivered in clearly marked packaging.

A truck is needed to lift off the pallet(s) with your delivery. If it is an indoor staircase, this delivery must be stored in a dry area indoors until assembly can take place.

There must be access to a changing room, break area and toilet. We also need an electrical connection at the assembly site. Materials for the stairs need to be lifted (truck, pallet lifter or crane) to the place where the stairs are to be assembled. If the stairs are more than one floor high, contact us after delivery to decide what you need to arrange in lifting aids or scaffolding so that we can mount the stairs safely.

Approximately one day per flight of stairs. One floor takes about one day, four floors about 4 days. More complicated stairs may take longer. Contact us for information on the estimated installation time for your particular staircase.

We attach great importance to our shipments being complete. Should there still be something you wonder about, contact our Support +46 (0)54 85 00 40 and we will help you quickly with this.

Eurostair® was founded in 1992, then under the name Nordiska Stålprodukter. Today, the company has sales offices and production in six countries and delivers to all of Northern Europe.

Eurostair® started in 1992, then under the name Nordiska Stålprodukter. The founder Tor Pederssen, who has a background as a pilot in commercial aviation, saw all the advantages of using high-strength steel in the production of steel products instead of ordinary "bonn steel". High-strength steel is still the foundation of Eurostairs products today.

Eurostair® today has sales throughout northern Europe. The group's head office is in Karlstad in Sweden and Eurostair® then has subsidiaries with sales offices or production in Sweden, Norway, Denmark, Poland and Germany.

It is a steel that is many times stronger than ordinary steel (the steel has a several times higher "yield strength"). This means that less steel can be used for the same strength in a construction, which thus has a significantly lower weight.

High-strength steel is more expensive than regular steel, but through less material consumption, the cost is optimized according to the strength requirements you have. High-strength steel also has a longer service life.

The important thing for a staircase to be classified as child-proof is that there are no vertical or horizontal openings larger than 100 mm. Our models listed as childproof meet these requirements.

It is the distance between the supervisor and the wall to make room for the fingers when you let your hand run with the supervisor.

It is the most common design on our stairs. An open staircase lacks the vertical risers that connect the landing steps. On straight stairs, child safety must be considered on these stairs. No opening on a child-proof staircase may have openings larger than 100 mm.

It is the height above the stairs measured vertically in the walking line on the step where the stairs pass under the joist edge, should be at least 2000 mm. On spiral stairs, too steep a slope can cause you to hit your head on the bottom edge of the steps above.

Left or right stairs are defined as standing down at the foot of the stairs and looking in which direction the stairs turn. In other words, when we step into the stairs, you turn left or right, that is "walking direction".

On a straight staircase, the slope between the floor and the handrail/beam is specified.

These are the slats that connect the wall piece/stair step with the baluster on the free side of the stairs.

There are load-bearing posts in the form of start, end and or corner posts. They are part of the railing construction.
