Sandwich elements save steel. Steel is recyclable.
Sustainable development is characterised by lower raw material usage per units produced and by products being recyclable.
Hitherto global production has increased at such a rate that consumption of raw materials has steadily increased.
Material efficiency is a competitive asset. Natural resources and material cost can be saved through use of material efficient structures. Material efficiency is also an image asset.
Laser welded metal sandwich structures often save 30-50 % of metal raw materials compared to traditional welded structures. The manufacturing of sandwich elements produces almost no waste materials.
Thanks to the light sandwich elements, lighter supporting structures and actuating mechanisms may in many cases be designed.
Steel is recyclable.
