Steel bars for pre-stressed concrete\PC steel bars
Steel bars for prestressed concrete developed by Nippon Koshuha Steel Group in 1960s are of high technical content. It is of high strength and toughness, low relaxation, strong grip of concrete, good weldability and upset forging, material-saving, etc. It also has been widely applied in high strength centrifugal pipe piles for prestressed concrete, poles, elevated bridge piers, and other prestressed components both at home and abroad, with a very broad market in the world, especially in Southeast Asia.
PC steel bars are a kind of low carbon alloy steel for heat treatment and high strength prestressed concrete, which is used in making port concrete pipe piles, high-rise building foundation concrete pipe piles, pier concrete pipe piles, etc. During production, prestressed concrete pipe piles (PHC) are produced in line with the building foundation basis through fixed cutting of the coiling steel bars, material cutting, heading, cage-making, feeding, tensioning, steam curing, etc.
