Product Overview
CRGO Coil (Cold-Rolled Grain-Oriented Silicon Steel Coil) is a grain-oriented electrical steel designed for magnetic cores in transformers and reactors. It is available across multiple international grade systems, including GB Q-series, Baosteel P-series and Hi-B R-series, JIS Z/ZH series, ASTM A876 grades, and DIN-EN material numbers.
The material is available in standard gauges of 0.23mm, 0.27mm, 0.30mm and 0.35mm, with ultra-thin customized material down to 0.18mm. Original coil width is 700–1250mm, while precision slitting can produce widths down to 20mm with ±0.1mm width tolerance. Standard coil ID is 508mm, with 610mm available by customization.
For different core manufacturing requirements, the CRGO Coil range provides C5, C6 and RoHS-compliant lead-free insulation coatings. Supply can also be combined with flattening and cut-to-length, EI lamination stamping, toroidal core winding, stress-relief annealing and laser cutting services.

FAQs
CRGO Coil is primarily used as grain-oriented electrical steel for magnetic cores in transformers and reactors. It is also specified for instrument transformers, photovoltaic inverter transformers, energy-storage reactors and other power-related equipment.
Standard thicknesses are 0.23 mm, 0.27 mm, 0.30 mm and 0.35 mm. Ultra-thin material down to 0.18 mm can be customized.
Yes. Precision slitting can produce widths down to 20 mm, with a stated width tolerance of ±0.1 mm. This is suitable for narrow-strip core-processing requirements.
Grade selection depends on the required material standard, thickness, magnetic-performance requirements, core design and application. The available range includes conventional grades, Hi-B grades and ultra-thin grades, so the required equipment and core specification should be provided for material matching.
Yes. The supplied service range includes flattening and cut-to-length, EI lamination stamping, toroidal core winding, stress-relief annealing and laser cutting.
