For construction companies
The next step – on schedule
We are the construction company’s partner when stairs need to be put in place without surprises. A clear process, own production, and installation keep the construction site moving and the schedule on track.

In a construction company’s everyday life, the schedule doesn’t flex and there are many subcontractors. When it comes to stairs, it means that delivery, dimensioning, and installation must hit the mark at once. We know this because we have been involved in construction sites for decades. When stairs come from us, they are made so that they can be installed as agreed and the construction site can continue without unnecessary waiting.
A process that supports the construction site
We handle stairs and related structures as a whole, so that the construction company gets one responsible party and less hassle. Design, manufacturing, and installation are handled by the same crew, and responsibility doesn’t bounce from one operator to another.
Modular production and our own quality control process ensure that only goods that are dimensionally and structurally sound leave for the construction site. CE-certified operations and documentation are ready, and they don’t need to be hunted down afterwards.
In addition, protective cages, railings, and other ancillary structures are delivered to the same package if necessary. One delivery, one schedule, one contact person.

LKDS – digital machine shop
LK Porras Design System (LKDS) is our way to make stair design faster and more reliably feasible. It combines design, dimensioning, and production into the same whole, so that solutions don’t just stay on paper.
- Speed: images suitable for the construction site and designers included already at the quotation stage
- Reliability: dimensioning and structures are based on modular solutions
- Smoothness: the plan moves directly to production without unnecessary intermediaries
