Interior Stairs
The Best-selling Interior Steel Stairs.
YS-STAIR
Custom-made, Direct Installation Type
This is our best-selling line of Indoor steel stairs—it uses dual-layered treads that effectively dampen sound.
These stairs are well suited for office building applications in high-rises and skyscrapers.

The dual-layered treads are light weight and effectively
dampen sound.
2.0mm steel plates are spot welded to create a dual-layered tread which dampens the sound of footsteps.
Our bending metal-plate processing yields rigid treads that are both light weight and high strength.
These are also high-performance stairs
for temporary installations.
The flat treads provide a sound walking surface and do not allow water to collect on them.
They are resistant to the wear and tear of temporary installations. They can provide a sound and safe route for your work space.
Finishing work can be easily and
safely performed on these stairs.
The stair surface is steel plating, which allows for simple surface preparation and sound and strong gluing of flooring materials.
The underside of the stair landings are also flat.
The flat structure of the underside of the stairs demonstrates its superior design qualities.
Exterior Stairs
Yokomori prides itself on the sound-proofing and anti-corrosion of its steel-framed stairs.
Z55-FRC
Four-Pillar Type

Gate-type four-pillar stairs are the standard.
These stairs have gate-type post and beam support for both floor-side landings and intermediate landings.
They are best suited as daily-use stairs in high-traffic buildings, such as apartment buildings.

Spiral / Ornamental Stairs
With our honed techniques and attention to detail,
we produce stairs of polished metal worthy enough to be called works of art.

Our team comes together
to produce master craftwork
At Yokomori, we incorporate computers into every step of our work process, from the design to the installation, to methodically and systematically manufacture stairs.
Yet, are you also aware of our team, and the reverence we have for experience, intuition, and above all, technical skill?

Skill further honed through ornamental metal work
Yokomori, now famous as a stairs maker, got its start in 1951 specializing in the design, fabrication and installation of metalwork for construction.
Since then, we applied our skills and entered into the field of ornamental metal work.
The various jobs we’ve had the pleasure of handling over the years have also honed the skills of our team.

Cultivated technical skill and works of art born from
attention to detail
This cultivated technical skill and attention to detail that have earned us our reputation in stair-making are still strong with us today, and we apply them to the beautiful ornamental staircases and advanced spiral staircases we make today.
We hope that you can catch a glimpse of the spirit of our craftsmen, who honor both form and beauty, in our stairs, which we would dare to call works of art.
Handrails
Handrails installed and highly precise, just like our indoor stairs. We offer a multitude of variations.
bon Handlails
Handrails for exterior stairs

The dual-layered treads are light weight and effectively
dampen sound.
The durability of these handrails, similar to our stairs comes from their strong anti-rust and tough hot-dipped galvanized design.
