Weights for motors with the required acceptances
Weights for automotive cranes with lugs, holes and stacking aids
Test weights, welded with exact weight specifications (weighing at the welding station)
Ballast material, without quality requirements also as additional weight for concrete weights
Filled weights with exact center of gravity
Weights for bridges and locks in complex shapes including pre-stacking at our premises
Base plates for vibration damping
Talk to us, we will find a solution together for all weight problems!
Welded structures
