PRODUCT FEATURE  
C/G BAR Further processed cold drawn bar which has surface beauty and tolerance precision. JIS h7 tolerances are assured for the application to precision machinery parts
Bar to Bar the Bar to Bar is a drawn bar that is used to pass the bar-shaped material (B/S Bar) through drawing dies to produce bars with a desired measure and improved surface roughness
Peeled BAR The peeled bar refers to a high-quality bar with a precise measure and enhanced roundness that is produced by continuously turning the surface of a rolled bar and thus removing meticulous defects from the surface.
ECT ECT is special CD Bar with a surface dectect. It is used in products that require superior sufrace quality including motor shaft, compressor pin, materials for hydraulic parts
