Reinforcing Steel

Reinforcing Steel (also called precision rolled threaded steel) are large-diameter, high-strength, high-dimensional precision straight bars with discontinuous external threads rolled on the entire steel bar. The steel bar can be connected with a connector with an internal thread or anchored with a threaded nut at any cross section.

ADVANTAGES

Core advantages of Reinforcing Steel:

Precision rolled threaded steel can be directly matched with special nuts for anchoring, without welding or threading, and has a tensile strength of 835MPa~1230MPa, which is more than 30% higher than ordinary rebar (HRB500 grade about 630MPa), and is suitable for lifeline projects that require long-term stable load-bearing or dynamic loads.

USE

Reinforcing Steel Application Areas:

Highway bridges, railway bridges, urban interchanges, urban light rail, high-rise buildings, water conservancy and hydropower dams, port terminals, rock slope anchoring, foundation reinforcement, tunnel mine top anchoring, etc.
