stairplane® staircases are normally specified by architects and installed by general contractors in the USA.   This site allows you to specify a staircase, which we can subsequently price for you. We have many more options not listed here, and will be happy to discuss our complete capabilities in our studio in New York or Los Angeles, or via Skype or telephone.   Send us your plans or your requirements via our Contact Form.


stairplane™ staircases are the result of 25 years of research and development, manufacturing experience using anodized aluminum and experience in thousands of staircase projects. The unique composition in the aluminum allows us to achieve strengths equal to steel, but with a fraction of the weight, making installation much easier. Aluminum also is a more refined metal than steel and does not give a dated look with time as most steel staircases. Some of our staircase designs were developed over 20 years ago, and like good classic design, are still used today due to their discrete, timeless aesthetic. You can find stairplane staircases in every European country, as well as in the US. We have technical solutions for practically every architectural wish and challenge, ask us.


stairplane™ CLASSIC
Our classic stairplane™ stringers are massive 10 mm brushed, anodised aluminium. This stringer is available in several heights which we optimise to achieve the most mimimal aesthetic and strength. The stringers can be natural anodised, color anodized or powder coated. These stringers weigh half of comparable steel stringers and have the same strength. All the bolts can be hidden.

stairplane™ CANTILEVER
CANTILEVER stairplane® stringers are manufactured using massive 65 mm anodised aluminium. This stringer allows us to create staircases with protruding steps, making the staircase appear more free-floating. There are no visible bolts. The unique width of this stringer also optimises the space needed for handrails.

stairplane™ FLOATING
FLOATING stairplane® stringers are single stringers, attached to a solid wall, which enable a full cantilevered step to be attached. This stringer can have illumination upwards or downwards, washing the wall with light. There are no visible bolts. Because this staircase can not have a railing attached to the outside of the step, we recommend a full-glass or solid wall for security.

stairplane™ BEAM
BEAM stairplane® stringers are an engineering wonder because they allow the treads to be attached using a gear-like structure, thus creating the correct angle of inclination. The staircase can be made relatively steep, and is thus a favorite for city lofts and ladder-type constructions for sleeping areas.

We offer 4 step shapes, and multiple colors and materials.

The TR260 step is an anodised wing-shaped step, like on an airplane. The step has a recessed black rubber insert to prevent slipping. The tread is 10.25” deep. This is the step shown on our homepage. It is absolutely cost-effective and is our best seller.

The TR240 step is an anodised aluminum step, with repeating ridges which create a very robust anti-skid surface. The tread is 9.5” deep. This step is often chosen for high-traffic areas or by families with children.

The TR280 step is our most customisable. It is manufactured using a very strong anodised alumuminum frame, and can have inserts of any color glass, natural stone, concrete, wood or aluminum slabs. It is also available ‘naked’ and you can insert your own material. The tread depth is customizable. This step is available in any color. The SLAB also comes in an XL version for extra-wide staircases with extra-thick steps.

The TR300 step is meant for public buildings, restaurants, offices, etc. where a very wide step is needed. The profile is extremely strong and can be made up to 70” in staircase width, without any steel. The step is almost 11.8” deep.


Most of our staircases can be manufactured with open or closed risers. All our glass, stone and wood versions fulfill US Building Regulations as long as your risers are 7 inches or less. If your risers are larger than 7 inches, we also have solutions to fulfill US Building Regulations. Ask us for more details.


We offer two kinds of code-compliant, sleek and minimal design railings for our staircases, landings, walkways and horizontal railings.

The framed glass railing is a minimal aluminum framed railing with a 9 mm safety glass, available in any color. The aluminum is natural anodised and is timeless. We can also color the railing in any RAL color you wish.

The full glass railings are just that, full glass, with no visible profiles. The glass is 21 mm, structural, safety glass, which can be manufactured in any color.

We also manufacture handrails in anodized aluminum and stainless steel. Some of our handrails can be illuminated from the bottom.


We can recommend excellent installers for our staircases in New York.   One flight of staircase generally takes approx. one day to install, depending on access and size.   Each staircase is made-to-measure in our factory, assembled to make sure every milling and every bolt works, then carefully disassembled and packed for transport.  Our stairs are high-value objects, and are generally installed in the later part of the construction phase when the final finishings in kitchen and bath are taking place.  Stairplane staircases are not anchored into the floor like traditional steel staircases, they are only fixed to the slab behind the upper step at the top.  This fixation takes place in either a wood or steel beam or concrete.


All our glass railings meet building codes. Some of our step solutions come in XL versions, which are extra thick and could meet the 4″ rule, others can be made code-compliant be adding our ‘safety’ bars placed high and discrete under each step. You can see how the safety bars look here.

The XL version for extra-wide staircases with extra-thick steps.
USA: No safety bars needed with riser < 176 mm
Switzerland: No safety bars needed with XL.

To determine what is best, send us your plans and your wishes. We have other solutions for meeting the 4″ code.


We deliver worldwide.  We have installers in New York, Denver and Miami should you need them, otherwise any contractor can install our staircases. We also have installers in Switzerland and southern Germany.


Manufacturing times are generally 6 weeks.   Delivery times (2-6 weeks) depend on where you are in the world and how much you want to spend on transport.  We have companies in Germany (billing in Euro) as well as Switzerland (billing in CHF) and the USA.  We accept checks (USA) and bank transfers. A formal quotation with our business conditions will be made once we receive your request and take contact with you.


Besides creating beautiful, timeless staircases, we also manufacture complex ones like the one below. General contractors and architects rely on us for high-end fit-outs, even though our product is priced comparable to steel staircases. Our streamlined production methods allow us to be very price-competitive for this kind of unique product. If you are near New York, please visit our showroom to see the impressive quality of our stairplane® staircases. We have extensive samples of all options.
