Traceability and documentation

Our certification, EN 1090-1 execution class EXC3, allows us to guarantee safe designs with thorough documentation. We can trace the origin of the material and ensure the quality of both materials and labour down to the finest weld. Our means of traceability is a reassuring approach that characterises STH Steel and makes us a highly reliable partner.

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.
