Client: Savon koulutuskuntayhtymä
Project: Steel structures for new construction sites in 2019–2022

Rakenneasennus acted as a subcontractor for YIT Rakennus Oy, responsible for extensive steel construction work at several sites.

We manufactured and installed the following steel structures and steel frames:

• A1 IVKH steel structures
• AB overpass steel frame
• Paint shop IV machine room structures
• Welding gas extraction building steel structures
• Steel frames for the glass walls at ends A, B and C

In addition, we manufactured and installed:

• Three mesh walls
• Steel pillars, tie rods, and windbreak frame
• Spark flap, masonry supports, and brackets
• Hot-dip galvanized corners and angle irons for parking spaces
• Grates and support frames

The project was completed on schedule, with particular attention paid to the functionality and durability of the structures in public spaces.

Client: Supervisual Oy
Project: Manufacture of digital LED displays for advertising locations

We were commissioned to manufacture frames for digital advertising displays for the Bella Ranta Water Sports Center, Bioteknia office building, and Matkus Shopping Center in Kuopio in 2023. The frames were made of steel, hot-dip galvanized and surface-treated in our production facilities, which guarantees a long service life and durability even in demanding conditions. The diagonal supports were welded on site and the whole structure was finished with quick-drying, rust-inhibiting polyurethane paint in the shade RAL5022.

In previous years, we have supplied display frames to several key advertising locations around Finland, including the Osuma Arena in Kuopio, Kainuu, Jyväskylä, and Oulu.

The delivery included beams, brackets, truss structures, and other necessary steel parts – all precisely designed and manufactured. The project combined technical expertise, durable construction, and visual appeal – exactly what an effective advertising solution requires.

Client: Finnish Transport Infrastructure Agency
Project: Development and improvement of railway sections 2018–2023

The Finnish Transport Infrastructure Agency implemented one of its largest railway projects to improve the flow of freight traffic, operational reliability, and the service level of railway sections. The project involved fundamental improvements to the tracks and new track sections, enabling an increase in the mass of transported goods and the axle load of wagons from 22.5 tons to 25 tons. In addition, the project involved the construction of 19 kilometers of new double track and 12 new bridges.

Key implementations:

We manufactured, painted, and installed the steel frame for the new light traffic bridge in Sienimäki on behalf of GRK. The bridge frame was manufactured in our machine shop as a single assembly:

• Weight 23 tons
• Length 30.4 meters
• Width 5.6 meters
• The surface treatment was carried out in accordance with LIVI A1 requirements, ensuring the durability of the structure.
• We were responsible for transporting the finished frame to the construction site.
• The bridge was installed by lifting it into place and attaching it to the bearing plates.

The project was completed efficiently and on schedule, ensuring a safe and durable light traffic connection to the area.

Customer: Yara Finland Ltd
Project: New steel structures for sulfuric acid production in 2024–2025

Yara has invested €235 million over five years in the renovation of its sulfuric acid production facility in Siilinjärvi. The aim of the project is to improve the reliability of the production process and enhance heat recovery, which will increase the plant’s energy efficiency and operational reliability.

Rakenneasennus carried out an extensive pipe bridge project, which included the design, manufacture, and installation of the pipe bridge and auxiliary structures.

We manufactured and installed steel structures such as:

• Pipe bridge frames and supports
• Pump bed
• 15 painted steel pipe bridge frames

A total of 280 tons of steel was used in the project. We carried out the work in close cooperation with other parties, ensuring that the structures met high quality and safety requirements and supported the objectives of the renovation.
