Introduction


CRB550 steel bar is used with ordinary reinforced concrete, other grades is the prestressed concret reinforcement.


Hot-rolled steel can become cold-rolled steel by cold processing, for example, to be cold-drawn, drawing at room temperature. Hot-rolled steel is low yield strength, good ductility properties. The cold-rolled steel bar have High yield strength, poor ductility properties. But they both have the ultimate tensile strength.

Cold-rolled ribbed steel bars are used hot rod multi-channel cold-reducing, a pressure ribs and reinforced a two or three crescent-shaped face with the elimination of internal stress after forming.

 

Intensity level three crescent-shaped cold-rolled ribbed steel roughly the same countries, both up and down in 550Mpa specifications 4─9mm. For ordinary reinforced concrete structures, such as the cast of the floor, foundation slab of muscle force and distribution muscle, tendon distributed shear walls, beams stirrups like.

 

Mechanical properties of reinforced international standards ISO105441992 (E) defined as follows: yield strength 500Mpa, tensile strength 550Mpa, elongation (gauge 5 times the diameter) of 12% (of elongation set δ10≥ 8% instead of δ12%).

 

Standard: GB GB13788-2008

Scope: reinforced concrete structure reinforcement force, welded steel mesh, stirrups, structural steel ...

Production process: the raw cold rolling and tempering line

Quality inspection cut to length Automatic receipts

Product Features: yield strength of 545-565MPa;

Tensile strength reached 600-625MPa;

Elongation (A5.65) of 18.5% to 22%;

Uniform growth rate (Agt) 5.17% -8.17%.

Different intensity levels of ribbed steel in the construction of the uses are different:

        1, CRB550 grade cold-rolled ribbed steel wire is made using HPB235 level disk rolling from the substrate. Often as a member of the reinforced concrete structure reinforced by the advocate, Ligament, stirrups, distribution bars, welded mesh reinforcement, structural reinforcement and prestressed tendons and other non.

        2, CRB650 grade cold-rolled ribbed steel wire is also used HPB235 grade rolled into the disc, and CRB800 grade cold-rolled ribbed steel bars is the use of low-alloy steel wire rod rolling disc. The two levels of cold-rolled ribbed steel commonly used in prestressed member.
