ERW · SAW · EFW

ERW

As we produce steel pipe products of various steel grades and sizes with sound welds through non-destructive testing, SeAH Steel has the largest production capacity and the best technology in Korea. Green products manufactured in safe workplaces serve a wide range of industries.

SAW

Based on the welding technology and know-how accumulated at the R&D welding research center, we secure optimal welding conditions and realize the best welding quality by applying a monitoring system. In particular, by applying the expander facility for the first time in Korea, we secure optimal dimensional quality and soundness of welds through non-destructive testing.
