Our Production Process

From raw material to final product — precision at every stage.

01

Raw Material

We use premium 82B wire rod from Rockcheck Group. Our self-developed no-pickling line ensures superior surface treatment.

Independent labs conduct chemical, mechanical, and relaxation tests on every coil.

02

Finished Product

Coils weigh 2.5–3.5 tons. Each is wrapped in waterproof cloth, secured with 16 steel strips, and mounted on wood pallets.

One 20ft container holds 8–10 coils (25–27 tons).

03

Export & Delivery

We ship globally with 7x24 support. Familiar with import/export policies in most countries.

Flexible payment terms. Unqualified products returned at our expense.
