With regards to material, our quality press-locked gratings made of high-solid high-strength steel strip are up to 50% more durable than gratings made of hot-rolled steel St 37.
At cyclical (changing) load, the service life is even up to 60% higher. Our quality material has a tensile strength of 600 N/mm2 (600 Kp/mm2), which allows it to bounce elastically and prevents deformation. Even after years of use, there are no “hammocks”.
In comparison, the utilisation factor for flexural strength for ProMetall press-locked gratings made of high-solid high-strength steel strip and gratings ST37 (example: 800×1,000 mm, mesh width 31×31 mm, supporting bar 30×2 mm)
