Spiral stairs<\/strong><\/p>\n\n\n\n

Spiral stairs are our specialty<\/h1>\n\n\n

We have been manufacturing spiral stairs for over five decades. When a project requires a space-efficient, durable, and properly dimensioned solution, spiral stairs are often the most functional option. And we know how to make them properly<\/p>\n\n\nContact us<\/a>\n\n<\/div>\n<\/div>\n<\/div>\n\n

Spiral stairs are part of a functional whole<\/h2>\n\n\n\n

Spiral stairs are not just a passageway, but part of the building’s structure and functionality. The spaces, loads, purpose of use, and regulations determine what kind of staircase actually works in the project. We always approach spiral stairs through the whole picture. Long experience from various projects helps in choosing the structure, treads, and railings so that the staircase is safe to use, easy to install, and stands the test of time.<\/p>\n\n<\/div>\n\n

How LK Portaat’s spiral stairs are made<\/h3>\n\n\n\n

Spiral stairs are designed here according to the project’s requirements and manufactured in our own production facility. Already at the quotation stage, illustrative images with 3D models are often included, which make it easy to understand and approve the whole before decisions are made. Each staircase goes through a clear quality control process, where dimensions and connections to buildings are checked before delivery.<\/p>\n\n\n\n

The modular structure facilitates transportation and speeds up installation on site. CE-certified operations and documentation are ready, and they don’t need to be requested separately. When a staircase leaves us, it must be ready to be installed, not to be modified on site<\/p>\n\n\n\n

And yes, we naturally deliver to the entire area of Finland and why not to Sweden as well.<\/p>\n\n<\/div>\n\n

\n\n

Design and modular components are our strengths<\/h3>\n\n\n\n

Spiral stairs are suitable for both indoor and outdoor projects, and the scale varies from a few steps to stairs over 100 meters. The structure is based on modular parts, such as treads and railings, some of which are ready in stock. This speeds up deliveries and facilitates project scheduling. The stairs are always designed according to the project’s conditions, so that the end result is functional, easy to install, and durable in use.<\/p>\n\n\n\n

If you want to install the stairs yourself, we naturally provide instructions and installation videos <\/p>\n\n\n\n
