AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company and a trading company, with a business scope covering import/export and sales of industrial and electronic products. It reports one production line, 11–20 quality-control staff, and flexible or minor customization for automatic packaging and slitting/cutting machinery. Product inspection instructions are available and uniformly followed, while complaint handling has a clear procedure and records. However, it has no available SDK, only one year of export experience, no overseas warehouse, showroom, agent or branch, and no reported offline trade-show participation. Sustainability and environmental-status information is unknown. The supplied information does not establish certifications, customer cases, or financial strength.

Supplier typeThe supplier is described as a combined company and a trading company. Its stated scope includes import and export of goods and technologies and sales of machinery-related, electrical, hardware, automotive, instrumentation and electronic products.

R&D capabilityThe supplier reports no available SDK, which is an explicit deficiency for SDK-based development capability. R&D engineer experience is listed as under five years, but no broader innovation output or development record is provided.

Production capacityThe supplier operates one production line and reports 11–20 quality-control staff. It has inspection instructions that are uniformly followed, but does not continuously reconcile quantities for each batch or mass production, indicating a documented production-control weakness.

Customization capabilityThe supplier explicitly offers flexible customization and minor customization for automatic packaging machines and automatic slitting and cutting machines. This directly supports a positive assessment of customization capability.

Product Q&A

Q:Do you supply prime quality Shougang CRGO steel coils with mill test certificates?

Yes, YAHE STEEL provides 100% prime quality Cold Rolled Grain Oriented (CRGO) electrical steel directly from leading mills like Shougang. Each shipment comes with an official Mill Test Certificate (MTC) verifying the core loss, magnetic permeability, and thickness specifications (such as 20SQGD or 23SQGD).

Q:Can you provide customized core slitting services for transformer silicon steel bands?

Absolutely. We are equipped with high-precision slitting machines capable of processing CRGO silicon steel coils into customized widths based on your transformer core drawings. We strictly control the slitting burr and width tolerance to ensure high-efficiency core lamination.

Q:What are your main thickness options and steel grades available for transformers?

We specialize in high-magnetic permeability electrical steel sheets and coils with thin specifications ranging from 0.18mm, 0.20mm, 0.23mm, to 0.30mm. Available grades include Shougang high-B series like 20SQGD070, 20SQGD075, 23SQGD080, and 23SQGD085.

Q:How do you pack and secure heavy 2-8 tons CRGO steel coils for ocean freight?

We provide standard sea-worthy export packing. Coils are wrapped in anti-rust paper and protective steel sheets, heavily strapped, and can be configured as Eye-to-Sky or Eye-to-Wall on reinforced wooden pallets. In the warehouse and during shipping, these heavy steel coils are placed on V-shaped tracks or secure flooring to prevent rolling or deformation.
