What core materials do you recommend?

We recommend Grain-Oriented Silicon Steel (GOES) like Hi-B or Laser-scribed Hi-B, or Amorphous Alloy for ultra-low loss applications.

What quality checks should be performed before purchase?

Request prototype tests for no-load loss and noise, verify Mill Test Certificates (MTC), and inspect joint consistency and insulation coating.

How do you handle packaging and logistics?

We ensure anti-rust protection with VCI paper or oil film, use strong wooden crates with shock protection, and provide moisture protection for sea shipment.

AI-Powered supplier vetting

SummaryThe supplier operates in metal structures, magnetic materials, transformer-related manufacturing, and distribution switch-control equipment. It demonstrates documented quality, warehouse, supplier-assessment, complaint-handling, and corrective-action procedures, supported by raw-material traceability, 100% finished-product inspection, and nine quality inspectors. It holds ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications. The supplier provides broad customization, ODM, and OEM services, with five R&D engineers supporting technical confirmation, product design, production, and after-sales service. However, it is not identified as a professional technical supplier, does not provide 3D software design or SDK services, and reported no new products in the past year. Evidence for overseas service coverage and customer cases is limited; the stated overseas-service country count is zero, while OEM for well-known brands is confirmed without customer names.

Supplier typeThe supplier is explicitly not classified as a professional technical supplier. Its stated business scope instead centers on metal structure manufacturing and sales, metal and magnetic materials, transformer-related manufacturing, and distribution switch-control equipment.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications, covering quality, occupational health and safety, environmental management, and energy management.

After-Sales capabilityFive technology engineers are responsible for technical support during production and after-sales service, while complaint handling has a clear procedure with records. However, the stated overseas-service country count is zero, so international service reach is not demonstrated.

Production capacityProduction capability is supported by listed cutting, laminating, testing, and uncoiling/slitting machines, nine quality-control inspectors, two quality-control test-equipment units, and a one-month average lead time in both peak and off-season. The stated business scope also includes multiple relevant manufacturing activities.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This range is stated consistently across the design-service records.

Product Q&A

Q:Which products can you provide?

We provide CRGO mother coils, slit coils, transformer lamination, and OEM transformer cores.

Q:Who are you and what is your background?

Established in 1988, we are pioneers in CRGO silicon steel products in China and exclusive users of Bao-steel, with a joint laboratory established with Baosteel.

Q:How do you guarantee product quality?

Our production adheres to ISO9001:2015 standards. Engineers perform meticulous calculations before orders, and rigorous tests are conducted post-production before dispatch.

Q:Why should I buy from you instead of other suppliers?

We have over 30 years of expertise, utilize advanced German slitting systems, and have an annual production capacity exceeding 100,000 tons.

Q:What are the key technical requirements to define before ordering?

You must define electrical parameters (type, rating, frequency, loss limits), core structure (type, joint, stacking factor), and lamination thickness.
