What are the main advantages of your stainless steel pipes?

The inner wall is smooth and not easy to scale, reducing bacterial infection risks. They are also 3 times stronger than steel pipe, resistant to earthquakes, and have low thermal conductivity suitable for high-temperature fluids.

Do you have production capacity to handle large orders?

Yes, we have three factories and an annual production capability of more than 15,000 tons. We formulate production plans to ensure completion on time.
