The following are some common standards for the materials of threaded steel and their corresponding regions:
Region | Standard |
---|---|
China | GB1499.2-2024 “Steel for Reinforced Concrete – Part 2: Hot Rolled Ribbed Bars” (To be implemented on September 25, 2024) Previously implemented standard was GB1499.2-2018 |
The United Kingdom | BS4449-1997/BS4449-2005 |
South Korea | KS D3504:2016 |
The United States | ASTM A615/A615M-2016, ASTM A706/706M-2016 |
Australia | AN/NZS 4672-2001 |
Malaysia | MS.146:2014 |
Costa Rica | ASTM A615/A615M-2016, ASTM A706/706M-2016 |
Brazil | ABNT NBR 7480 |
These standards may have differences in chemical composition, mechanical properties, dimensional tolerances, etc. Different countries and regions have formulated corresponding threaded steel standards based on their own construction needs, industrial development levels, and quality requirements to ensure the safe and reliable use of threaded steel in buildings and engineering.
When conducting international trade or cross-regional construction projects, special attention needs to be paid to whether the threaded steel adopted meets the local standard requirements. At the same time, with the continuous development and progress of technology, these standards may also be updated and revised. It is recommended to pay attention to the latest developments of relevant standards.
