Sonderdyn mats for increased dynamic stress

Sonderdyn mats made of concrete reinforcement steel of steel grades B500A (material 1.0438) or B500B (material 1.0439) in accordance with DIN-488-1:2009-08, regulated by DIN 488-4:2009-08, are reinforcement mats used in structures with increased dynamic loads. With these reinforcement mats, the longitudinal and transverse rods are only welded in the edge area, permitting a fatigue endurance for the reinforcement.
