Frequently Asked Questions

What is the difference between CRGO and CRNGO?

CRGO (Cold-Rolled Grain-Oriented) steel has superior magnetic properties in one direction, ideal for transformer cores. CRNGO (Cold-Rolled Non-Oriented) has uniform properties in all directions, used in motors and generators.

Can you customize core sizes and shapes?

Yes, we offer custom engineering for stacked cores, EI cores, unicores, and toroidal cores to meet your exact specifications.

Do you provide technical support?

Absolutely. Our team provides full technical support, from material selection to machine integration and troubleshooting.

What are your delivery times?

Standard products ship within 7–15 days. Custom orders typically take 20–30 days depending on complexity.
