The strength grade of GR40 Rebar is 40ksi, which is equivalent to the national standard HRB335 steel bar and can meet the needs of different projects.
HPB355 Rebar is a high-strength steel, also known as steel for prestressed concrete. It has high yield strength and tensile strength, mainly used in prestressed concrete structures, and can provide better bearing capacity and stability.
CA50 Rebar is a high-strength, high toughness, and low relaxation prestressed steel strand made of low-carbon steel and high-strength steel wire. It has excellent tensile performance, toughness, and plasticity, and can withstand various complex environmental and load conditions.
Rebar is the common name for hot rolled ribbed steel bars. H, R and B are the first letters of the words Hotrolled, Ribbed and Bars respectively.
Hot rolled ribbed steel bars are divided into three grades: HRB335 (old grade 20MnSi), HRB400 (old grade 20MnSiV, 20MnSiNb, 20Mnti) and HRB500.
Rebar is the steel that must be used for medium-sized building components and above. The geometry of the cross-rib of rebar is mainly spiral, herringbone and crescent-shaped. The principle of ordering rebar is generally based on the mechanical process performance or mechanical strength index to meet the grip performance requirements of engineering design.
