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.
Rolling Mark & Tag
We repeatedly mark the country of origin, manufacturer, nominal diameter, and grade of steel on the surface of reinforcing bar at intervals of less than 1.5m. Furthermore, a color tag (TAG) is attached to the product cross-section.
