Reinforcing Bar

HANSCO products are produced with the latest equipment and superior technologies. Even a small product is strictly controlled for the production of products demanded by customers. In the case of high-strength reinforcing bar such as SD400, SD500, and SD600 among our manufactured products, we produce reinforcing bar with superior quality by forming a hardened layer through a rapid cooling process on the surface with water cooling (TEMPCORE) reinforcing bar production method. In addition, we are manufacturing products with various specifications and sizes including special reinforcing bar and seismic proof reinforcing bar according to the rising demand for high-strength seismic proof reinforcing bar. We will continuously respond to the demands of our consumers through constant research & development.

(1) Tensile strength is the ratio of actually measured yield strength, which must be over the stipulated ratio.

(2) Regarding the dimension exceeding D32 among deformed bars, subtract 2 from the value of elongation percentage in the table every time the designation name 3 increases. However, the limit of subtraction shall be 4.
