Materials
Maximum economic efficiency through extensive prefabrication, excellent dimensional accuracy, extremely short construction periods and favorable behavior even under dynamic loads – arguments in favor of steel are unbeatable. We invest our know-how and resources to push the limits and produce steels of particularly high quality.
We deliver all profile dimensions according to the national and international standard norms for construction steel and fine-grained steel, offshore and shipbuilding steel and also in particular specifications. Special products like mining profiles are offered in the corresponding steel sorts.
Selection
Steel grades | Standard |
|---|---|
Structural steels | EN 10025 |
Fine grain structural steels | EN 10113 |
Weather resistant steels | EN 10155 |
Heat resistant steels | EN 10028 |
Steels for offshore constructions | EN 10225 |
Sheet piling steels | EN 10248 |
Mine support section steels | DIN 21530 + 17 Mn V7 |
Ship building steels | Spez. gem. DNC, GL, LRS, BV, ABS etc. |
Further steel grades upon request | e.g.: BS, NF, ASTM, JIS, CSAG, GOST, UNI |
Our steel grades are successfully used not only in offshore technology, but in general in all fields of steel structures, bridge, vehicle, crane, and reactor construction and in shipbuilding.
Carbon equivalent value and weldability
The high-strength steel grades offer excellent weldability due to their extremely low carbon equivalent value (CEV). They may be welded without preheating for the most part. We guarantee a maximum carbon equivalent value of:
- 0,39 % for S355
- 0,42 % for S420
- 0,43 % for S460
Properties in the product's throughthickness direction
Our steel grades are also offered with guaranteed properties in through-thickness appropriate EN10164. This eliminates the risk of lamellar tearing.
