Steel Round Bar

Diameter: The diameter of round steel bars typically ranges from 5.5mm to 250mm. 

Common diameters include 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm, and 50mm.

Types of round steel include low-alloy structural steel bars, alloy structural steel, free-cutting non-heat-treated steel, and stainless steel round bars. Based on surface treatment, they can also be classified into bright bars and black bars. Each type of round steel is selected based on its strength, toughness, corrosion resistance, and application requirements.

1.Low-alloy structural steel

refers to a type of alloy steel with an alloy element content of less than 3%, encompassing many standard and proprietary grades designed to provide specific combinations of desired properties, such as toughness, strength, formability, weldability, and atmospheric corrosion resistance.

2.Alloy structural steel
Alloy structural steel is a type of steel formed by adding different proportions of alloying elements such as manganese, chromium, nickel, molybdenum, and vanadium.  The purpose of this is to improve the mechanical and physical properties of ordinary carbon steel, such as hardenability, tensile strength, yield ratio, fatigue strength, ductility, and corrosion resistance, making these types of steel suitable for manufacturing various mechanical parts with larger cross-sectional dimensions.

3.Free-machining steel round bar

Free-machining steel is a type of steel alloyed with elements such as sulfur, lead, bismuth, phosphorus, selenium, and tellurium.  The addition of these elements ensures that chips break off easily during machining, thus reducing machining forces, extending tool life, and improving the surface finish of the machined parts. This makes it ideal for applications where machining speed and surface finish are primary requirements.

4.Stainless Steel Round Bar
Stainless steel round bar is a solid bar made of stainless steel, possessing excellent corrosion resistance, strength, and durability. It is widely used in mechanical manufacturing and industrial applications.

Rebar is usually made of low alloy steel or carbon structural steel. Its main components include carbon, silicon, manganese, phosphorus, sulfur, etc. These elements give rebar excellent strength, toughness and plasticity.Rebar has the characteristics of high strength, good plasticity, strong toughness and good weldability. These characteristics enable rebar to meet the requirements of steel strength and durability for various building structures.

The main application field of rebar is in construction engineering, especially in reinforced concrete structures. It is widely used for reinforcing the beams, columns, slabs, walls and other components of various buildings, to enhance the bearing capacity, seismic performance and durability of the structure.
