At Histeel Haman Plant, We produce jumbo-sized anti-seismic square tubes which are used for civil engineering,
general construction, steel structure fabrication and etc..
We acquired KS D3864 << carbon steel square pipes for building structure >> to assure the quality of products
and developed unique 1 seam forming method capable up to 1000x1000.
Such unique forming technology at Histeel Haman Plant not only enables productivity improvement and cost reduction,
but also contributes to Green Growth thanks to reduced weld zone.
