We can supply a wide variety of cross-sectional shapes at high quality and low cost, with our profile rolling technology accumulated over many years and the introduction of the latest profile processing equipment and inspection devices.
Replacing conventional ‘grinding and cutting’ with our precision profiled steel can lead to unprecedented and dramatic cost reductions.

Precise Tubes(Fine Pipe)

Precise Tube (Fine Pipe)

We have developed the welded and drawn pipe "FINE PIPE", which is superior to the "seamless pipe", using carefully selected materials and original processing technology that only a materials manufacturer can achieve.
We provide high-quality, low-cost products by using proprietary processing (welding, drawing, annealing) developed in-house and the latest specialized equipment.
