Grotnes Steel
Steel cutting, heat treatment and advanced processing for industry. Grotnes Steel is part of the Miras Group and operates under the same ownership as Nordic Green Products.
Advanced steel processing for demanding applications
Grotnes Steel is a specialised steel cutting centre and development company based in Mo i Rana. With a history dating back to 1969, the company delivers advanced steel processing services to clients worldwide, supporting industries where precision, material performance and reliability are critical.
As part of the Miras Group, Grotnes Steel shares ownership with Nordic Green Products and represents a related company within the same industrial group structure.
Technical services for critical components
Grotnes Steel focuses on processing thick steel materials into near-finished components with high precision and tight tolerances.
Their capabilities include advanced cutting technologies, heat treatment and further processing of steel components. These processes enable efficient production of complex parts, often reducing the need for extensive downstream machining.
The focus is on delivering components that ensure predictable performance in demanding industrial applications.
Cutting technology and material expertise
Grotnes Steel is recognised for its expertise in heavy steel plate processing and advanced cutting methods.
In 2025 they bought a laser cutting machine whit 30kWh effect, and can cut mild steel, and stainless steel from 1 to 60mm thickness. The capacity of plates it can cut is 3000x9000mm.
This is a fast production method and has very precise tolerance. (+-0,1mm.)
In addition, a grinding machine is in place in August 2026. Capacity of 1500mm with, and 100mm height.
The company processes a wide range of steel thicknesses using CNC-controlled systems and specialised techniques developed over time. This allows for precise shaping of components with complex geometries and strict tolerances.
Their work supports industries where both material quality and execution accuracy are critical.
Heat treatment and production support
In addition to cutting, Grotnes Steel provides heat treatment processes that ensure consistent material properties and structural integrity.
The company also supports customers throughout the production process, contributing to efficient project execution from raw material to finished component.
Industries served
Grotnes Steel supports industries where material performance and precision are essential, including oil and gas, offshore energy, hydropower, infrastructure and heavy industry.
Their experience with demanding requirements enables reliable delivery of components used in critical applications.
Relationship to Nordic Green Products
Grotnes Steel is part of the Miras Group and operates under the same ownership as Nordic Green Products.
While the companies operate independently, they share a common industrial foundation and ownership structure within the group.
