Quality assurance is integrated into every stage of material supply and processing. We support industrial customers with production-oriented quality control, documentation and traceability for GOES and transformer lamination projects.
Grain Oriented Electrical Steel is mainly used for transformer core manufacturing and other magnetic core applications that require high permeability and low core loss in the rolling direction.
GOES is designed for directional magnetic performance and is primarily used in transformers, while non-grain oriented electrical steel is more commonly used in motors and rotating equipment.
Our GOES products are suitable for power transformers, distribution transformers, dry-type transformers and other laminated magnetic core applications.
Yes. We supply GOES in coils and slit coils according to customer requirements.
