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.

| Length | Below 7m | + 40mm | |
| 0 | |||
| Exceeding 7m | Every time the length of 1m or its singular number increases, add 5mm to the tolerance above. However, maximum value shall be limited up to 120mm. | ||
Remarks
- 1) It is not applied to a coil.
- 2) Dimension besides standard length follows the discussion between the orderer and manufacturer.
