Industrial steel products and services

We supply large-scale steel products manufactured by welding, cold forming and heat treatment to various industries. We also serve our customers in industrial installation, maintenance and service work.

strong plate products

We manufacture demanding heavy-duty sheet metal products for industrial needs – with precise dimensions and certified methods. Our products include:

  • Tanks, silos and pressure vessels – also made of stainless and acid-resistant steel
  • Duct systems and components – for the energy and process industries
  • Offshore products – for the harshest conditions, in accordance with international standards
  • Steel structures – for heavy industry, also based on customer designs
  • Clarifiers, thickeners and on-site tanks – tailored solutions for water treatment and process needs

Heavy steel constructions

We design and manufacture heavy-duty steel structures for challenging industrial applications. The upper limit on part sizes and weights is not a problem – our production facility in Ii is built to handle large assemblies.

bended products

IKP specializes in the production of large-sized rotating parts. We have efficient equipment and decades of experience.

  • Sheet bending
  • Cylinders, cones
  • Lime kilns
  • Peeling drum
  • Granulating drums

3D Laser Cutting coming 1/2026

Iin Konepaja oy has acquired Europe's most modern and largest Bodor 60 kW 3D laser cutting equipment. The installation and commissioning of the laser will take place during the last quarter (Q4) of 2025.

With this Bodor 60kW 3D laser cutting machine, we are able to serve customers with sheet thicknesses of 5-80mm, up to 100mm material thicknesses. The result is an extremely precise cut result and quality. With the equipment, we are able to cut complex three-dimensional shapes, such as bevels.

Thanks to the large cutting table area (14m x 4m) of the laser cutting equipment, we are able to offer cutting and subcontracting services for very large pieces to our partners.

Our laser cutting equipment is suitable for cutting both carbon steel and bright steel grades. Our versatile cutting programs also offer solutions, especially for fast subcontracting needs. Sheet utilization optimization and simulation runs are also possible with the help of our versatile software package.

Machining services

We offer a wide range of machining services for heavy industry. Large-scale processing and precision are our specialties.

  • Carousel turning – large diameter parts, precisely and efficiently
  • Grinding – finishing with machine precision
  • Drilling – deep hole drilling and line drilling for large steel parts

Workshop services

IKP's mechanical engineering expertise covers a wide range of design, manufacturing and machining solutions. We combine mechanical structural design, practical implementation and reliable project management.

Line and countersinking drilling

IKP offers precise line drilling suitable for large-sized parts. The service can be carried out in the factory or on site at the customer's premises.

Surface treatments

IKP's surface treatment solutions ensure the durability of products even in demanding conditions. We carry out sandblasting, painting and rust protection according to customer requirements.

Plasma and flame cutting

We cut even strong sheets with plasma and flame cutting accurately and efficiently. Our services enable dimensionally accurate pieces for further production stages.

Design services

We provide design and implementation from the same source. Whether it's a machine part, a tank or a steel structure, we design technical solutions efficiently, safely and in a production-friendly manner.
