Description

Steel rebar is not only an essential material in construction engineering, but also plays a key role in machinery manufacturing and many other fields. Our company is strong, sufficient inventory, can produce and supply various specifications of steel rebar, rebar, steel wire, H-shaped steel, Angle steel, channel steel, etc., welcome to negotiate cooperation.

Classification of Steel Rebar:

Steel Rebar refers to steel for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. Including plain round steel bars, ribbed steel bars, and torsion steel bars. , its cross-section is circular, sometimes square with rounded corners. Including plain round steel bars, ribbed steel bars, and twisted steel bars.

1. Divide according to diameter
Steel wire (diameter 3~5mm), thin steel bar (diameter 6~10mm), thick steel bar (diameter greater than 22mm).

2. According to mechanical properties
Grade I steel bars (Grade 300/420); Grade II steel bars (Grade 335/455); Grade III steel bars (400/540) and Grade IV steel bars (500/630)

3. According to production technology
Hot-rolled, cold-rolled, cold-drawn steel bars, as well as heat-treated steel bars made of grade IV steel bars, have higher strength than the former.

4. Divide according to the role in the structure
Compression steel bars, tension steel bars, erecting steel bars, distributed steel bars, stirrups, etc.

Applications of Steel Rebar:

Steel rebar is primarily used in reinforced concrete structures to bear tensile forces and enhance crack resistance and seismic resistance. It is widely used in load-bearing components such as beams, columns, slabs, walls, and foundations in civil engineering projects such as buildings, bridges, and roads.

1. Solid Reinforcing Bars: Steel rebars are placed in beams, slabs, columns, and walls to bear tensile or compressive stresses (e.g., HRB400/500 ribbed steel bars used as main reinforcement).

2. Stirrups and Structural Reinforcement: Steel rebars are used at beam-column joints for shear resistance and to fix the position of main reinforcement (e.g., HPB300 plain round steel bars or HRB series stirrups).

3. Distribution and Temperature Reinforcement: Steel rebars are placed in floor slabs and roof slabs to distribute loads and control temperature cracking.

4. Prestressed Steel Reinforcement (e.g., steel strand, precision-rolled threaded steel): Steel rebars are used in long-span bridges, high-rise buildings, and special structures to enhance stiffness and crack resistance through prestressing.

5. Foundation and subgrade components: used in pile foundations, pile caps, and raft foundations to resist uneven settlement and bending moments.

6. Bearing capacity engineering.

7. Non-structural components: such as precast components, retaining walls, pipe galleries, chimneys, etc., equipped with steel rebar according to structural requirements.
