Steel structures for wastewater treatment plants and heating plants

We have manufactured frame structures and complementary structures for several wastewater treatment plants and heating plants in Eastern Finland.

For new plants we offer:

  • Frame structures
  • Railings and other complementary structures

All our structures are manufactured to the highest industry standards, ensuring durability and safety in the demanding conditions of infrastructure construction.

Durable and reliable steel construction for critical infrastructure.

Steel solutions for waterways and ports

With decades of experience, we offer durable and customized steel structures for waterways and ports. Our services cover fabrication and surface treatment, and we operate throughout Finland.

We manufacture e.g.:

  • Sea and ice cones
  • Locks, sluice gates and fishways
  • Bridge structures, other structures

All our structures are designed to withstand demanding environmental conditions – ensuring their longevity and reliable operation. In design and construction, we take into account industrial surface treatment standards and the specific requirements of the structure’s future use.

We paint structures for use in both climatic and submerged applications. Our special expertise is in waterborne coating systems, which provide protection even in extreme conditions.

Durable, high-quality steel construction for waterways and ports.

Surface treatment solutions for infrared structures

Infrastructures are constantly exposed to high load, so the right choice of material and surface treatment are key. We offer high-quality surface treatment solutions that protect structures and extend their lifetime.

Our services include:

  • Sandblasting – an effective method of surface preparation
  • Painting – protects and finishes the structure
  • Hot dip galvanizing – long-lasting corrosion protection

We carry out all surface treatment steps flexibly in our own facilities, ensuring a high-quality finish.

Durable surface treatment – long-lasting, high-quality structures.
