Solving Construction's Biggest Challenges
Construction productivity, energy efficiency, and quality are compromised by traditional methods and complexity. SteelLeanel’s patented prefab wall system with fully robotic next-generation wall manufacturing cuts costs, speeds up construction, and improves quality and energy efficiency.
One Sqm of Wall in Just 36 Seconds
Robots handle the whole wall manufacturing process. Even the insulation.
Simple
A patented prefab wall structure designed specifically for robotized manufacturing. Reduces manual labor by 80% and decreases construction costs by one-third.
Sustainable
Reduces building energy consumption by 60%. Allows for great recyclability and reusability of materials, minimizing waste and reducing use of virgin materials.
Safe
Designed for safety, resiliency in every climate, and long-term energy efficiency and durability. Validated by leading independent scientific experts.
Superior wall structure
Disruptive use of the best materials and joining methods.
- Airtight structure without thermal bridging
- No separate Air and Vapour Control Layers (AVCL)
- Installation space for wiring and additional insulation
- Non-combustible frame
- Non-organic, moisture-safe structure
- Freedom to choose inner and outer claddings
For New Construction and Renovation
No design constraints. Adaptable to every region, building code and climate.
New construction
SteelLeanel prefabs serve as a load-bearing or an infill wall. A versatile solution for new building projects.
Renovation
Ideal for facade and energy renovations, where the existing load-bearing structure is being preserved.
Additional floors
Add floors to existing buildings using lightweight SteelLeanel prefabs and modules without design constraints.
SteelLeanel Prefab Line
World’s first prefab line to assemble frame and insulation with robots in one go.
Manual labour: 0,09 h / sqm
Capacity: 300 000 sqm / year
Payback period: 2 years
A Scalable Solution for a Booming Market
The world is expected to add a New York City’s worth of buildings every month for the next 40 years. Traditional methods can’t keep up with this pace. SteelLeanel can.

“SteelLeanel can help solve two big problems in construction business – low productivity and varying quality.”

“We believe that SteelLeanel can be a breakthrough solution to nZEB challenges.”
Pekka Roivio
Director, Ruukki Construction
“SteelLeanel structure has a very good potential to fulfil the moisture-safe hygrothermal behaviour and the nZEB requirements in much more controlled way than many existing wooden frame solutions. One-layer insulation without leaking seams, optimal steel frame and insulation dimensions, as well as right material choices will make this difference.”

Our Story
With extensive experience in construction and materials technology, we applied LEAN principles to transform wall manufacturing. Over the years, we’ve successfully completed more than 20 projects utilizing wood-frame structures as proof of concept (PoC) for robotized manufacturing.
SteelLeanel holds 22 patents in 22 countries, covering two billion people. The wall structure’s validated physical properties include structural integrity, sound insulation, and hygrothermal performance. As a digital proof of concept, we simulated the manufacturing process and expect to reach a yearly production capacity of 300,000 square meters upon full commercialization. This is what next-generation wall manufacturing looks like.
