A multi-material portfolio organised the way engineers and buyers search: by material, form and grade. Each family opens into structured specifications and documents.
We work from your specification, not a fixed price list — combining a broad material portfolio with the documentation and follow-through international procurement needs.
Talk to our team
Steel, electrical steel, copper, aluminum, machinery and components from one point of contact.
Shipped directly from China to India and other overseas markets, with import & export handled as part of supply.
Grade, standard, dimensions and tolerances come first — every enquiry is reviewed against your technical requirement.
Datasheets, grade references and manuals organised by product, so engineering teams can check before they ask.
Quotation requests capture product, grade, quantity and destination up front — fewer back-and-forth emails.
General mechanical equipment installation and maintenance of electronic & mechanical equipment.
Electrical steel is chosen on core loss, magnetic induction and thickness. We supply grain-oriented and non-grain-oriented coils and help buyers match grades to their transformer, motor and reactor designs.
Conventional, high-induction and domain-refined types for power and distribution transformer cores.
Uniform magnetic properties in all directions, for rotating machines such as motors.
Example from the supplied reference manual: B27R090.
| Grade | Type | Nominal thickness (mm) | P1.7/50 max (W/kg) | B8 min (T) |
|---|---|---|---|---|
| B27G120 | Conventional | 0.27 | ≤ 1.20 | ≥ 1.80 |
| B30P105 | High induction | 0.30 | ≤ 1.05 | ≥ 1.88 |
| B27R090 | Domain-refined | 0.27 | ≤ 0.90 | ≥ 1.87 |
| B23R080 | Domain-refined | 0.23 | ≤ 0.80 | ≥ 1.87 |
