Do you know the main categories of threaded steel?

1.What is threaded steel?

Screw thread steel is a commonly used building material in the construction industry. It is embedded in concrete to enhance the compressive strength of concrete.

2. Classification of threaded steel

There are usually two main classification methods for threaded steel.

According to the shape of the thread, threaded steel is mainly divided into two types: ordinary threaded steel and deformed threaded steel. Ordinary threaded steel has a fixed thread shape with the same diameter at the top and bottom of the thread; Deformed threaded steel has a variable thread shape, with the diameter at the top of the thread being smaller than the diameter at the bottom.

According to the strength level, threaded steel is also divided into three types: HRB335, HRB400, and HRB500. Among them, HRB335 can be used in small civil buildings, while HRB400 and HRB500 are widely used in industrial and large civil buildings.

3. Characteristics of threaded steel

Compared with ordinary steel bars, deformed steel bars have an increased surface area, which enhances their load-bearing capacity and has good tensile properties; In order to prevent steel bars from loosening in concrete, the surface of the threaded steel has a layer of raised threads, which can increase friction force; Due to the presence of threads on the surface of threaded steel, it can bond more tightly with concrete, improving the bonding force between steel bars and concrete.

4. Application of threaded steel

Threaded steel is widely used in civil engineering construction such as houses, bridges, and roads. From public facilities such as highways, railways, bridges, culverts, tunnels, flood control, dams, to the foundations, beams, columns, walls, slabs, and threaded steel bars of building structures, they are all indispensable structural materials.
