Deformed bar studs

Contact us for the details of length, bending angle and etc.
Contact us for the any shape, we may provide, except below.
Two kinds of deformed bar stud materials, KSW-400 and KSW-490 developed jointly with Kobe Steel, are applied for stud welding methods of pile foundation, shear wall and base anchor fitting.
