Easy Access to Yard
All-aluminum means NO Rust!
This prefabricated aluminum spiral staircase links two living areas into a single space. No more walking through the house to reach the pool. Our Japanese spiral staircases are constructed entirely from aluminum, featuring profile aluminum railings and cast aluminum steps and core.
Cast-Aluminum plus Profile-Aluminum
The railing is made of aluminum profiles to reduce the overall weight and cost of this exquisite outdoor staircase. The steps, however, must support heavy loads and are therefore made of cast aluminum.
Here is more detail on our aluminum staircases from Japan.
Top Quality in the Details
As with all our aluminum outdoor products, the Japanese engineers have addressed every little detail, such as sealing every opening to prevent moisture with specific caps and connectors.
Landing with Rails, Gate, and Floor with Gutter
There are several flooring options for the landing, all of which incorporate a gutter system. The landing also has a security gate with a lock upstairs, so children cannot use the outdoor stairs unsupervised.
Easy to connect the upper floor to the yard
Japanese aluminum outdoor stairs will arrive at your door as a complete staircase kit, including everything needed for installation. There are also straight staircases only made of aluminum profiles. See Details on our website.
Detailed measurements must be taken to ensure the staircase is exactly as needed for a specific site. KunkelWorks USA is here to help with these details to ensure a successful project. Contact us to learn more about our Japanese aluminum outdoor staircases.
