Frequently Asked Questions

What is the difference between RP, HP, and UHP graphite electrodes?

RP (Regular Power) electrodes are used in standard applications with lower current density. HP (High Power) electrodes handle higher currents and are suitable for larger furnaces. UHP (Ultra High Power) electrodes are designed for the most demanding environments, offering superior thermal and electrical conductivity, mechanical strength, and oxidation resistance.

What diameters do you offer?

We manufacture graphite electrodes in diameters ranging from Φ200 mm to Φ650 mm, covering a wide range of industrial furnace requirements.

Can you provide custom sizes or packaging?

Yes, we offer customization for both product dimensions and packaging to meet specific customer needs, including OEM labeling and special crating for export.

What is your production capacity?

Our annual production capacity is 30,000 tons, allowing us to fulfill large-volume orders efficiently and maintain short lead times.

Do you supply raw materials like needle coke?

While we primarily use petroleum needle coke as a key raw material for our electrodes, we focus on finished product manufacturing. Please contact us for specific material inquiries.
