The construction industry is increasingly moving towards modular building processes to streamline work and shorten labour time at the final destination.

STH Steel has extensive experience in manufacturing modules, meaning load-bearing steel frames, which are transported to module factories where they are equipped into complete units with, for example, ready-made electrical and pipework systems. These units are then connected to form large factory facilities at the final destination and become pharmaceutical factories or facilities for the mining and manufacturing industry among other things.

Capacity for large orders

We have spacious and well-designed facilities to produce numerous large module frames efficiently. For example, a single module can be 14 metres long and 4.5 metres wide. A factory may need over 100 such modules to build a multi-level facility covering thousands of square metres.

  • Factory plants made of steel modules
  • Carefully designed construction planning
  • Professional welding
  • International shipping

Our projects

Welding work for every level of difficulty

To us, steel is more than a material. It is an expression of our unyielding will and our creative ability to overcome obstacles. This approach guides us as we offer our steel solutions across country borders, installing them on high rooftops or deep down in the dark bedrock of the earth.

Wherever safe and professional steel structures are needed to sustain the needs of the industry and society, there you will find STH Steel.
