Screw thread steel is widely used in infrastructure construction such as buildings, bridges, roads, and tunnels. In concrete structures, rebar is mainly used to reinforce and enhance the tensile performance of concrete, improve the bearing capacity and stability of buildings. In addition, in earthquake prone areas, the use of threaded steel can effectively improve the seismic performance of buildings and ensure the safety of people's lives and property.

Due to the presence of longitudinal and transverse ribs (spiral, herringbone, and crescent) on the surface of rebar, it significantly increases the bonding strength with concrete. This special structure enables the rebar to form a strong gripping force in concrete, effectively preventing problems such as concrete cracking and steel corrosion. At the same time, threaded steel has high strength and toughness, and can withstand large tensile and compressive forces, providing stable and reliable support for buildings.
