Rebar
Carbon Steel Reinforcing Bar (Rebar)
Carbon steel is the most common form of steel rebar (short for reinforcing bar or reinforcing steel). Rebar is commonly used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression.
Wire rod is a rolled steel bar commonly used on construction sites, with diameters of 6, 8, 10, and 12 millimeters. It is mostly made of low carbon steel and is not commonly used as the main reinforcement in reinforced concrete structures. It is mostly used to make steel sleeves, and small diameters are used for "brick reinforcement" in brick concrete structures.
HPB300/HRB335 Reinforcement Rebar
HPB300 grade: The yield strength of steel bars in this grade is 300MPa, with high plasticity and toughness, suitable for general structural reinforcement and stirrups. HRB335 grade: The yield strength of this grade of steel bars is 335MPa, with high strength and good ductility, suitable for general structural reinforcement and stirrups, especially for projects with high strength requirements.
HRB400/HRB400E Deformed Steel Rebar
HRB400,As a model of hot-rolled ribbed steel bars. HRB "is the identification of steel bars used in concrete, while" 400 "indicates a tensile strength of 400MPa, which is the maximum stress that the steel bars can withstand under tension.
HRB500/HRB500E Deformed Steel Rebar
500 indicates that the tensile strength of steel bars is 500 megapascals (MPa). Tensile strength is an indicator of the ability of steel bars to resist tensile forces. The tensile strength of HRB500 belongs to the category of high-strength steel bars and is suitable for engineering projects that require high strength.
HRB600 High Strength Reinforced Bar
The yield strength standard value of HRB600 steel bars is 600MPa, which belongs to high-strength steel bars. In the new national standard, it is clearly classified as Grade 5 rebar, which is one of the high-strength steel bars in the field of civil construction.
European standard grades for steel products follow a set naming structure. Each grade starts with a single letter, and is followed by a number. The letter relates to the application and the number relates to the yield strength of the steel. Steel used for reinforcing concrete has the application letter B, and the number 500, which represents a minimum yield strength of 500MPa. The grades for reinforcement steel then have a final letter A, B or C.
BS 4449: 2005 uses the term 'bar' for ribbed reinforcing steel. The terms 'rod' and 'wire' should be restricted to describe reinforcing steel in coil, or wire in reinforced concrete products.
A615 steel rebar has a rough, blue-grey finish with raised ribs throughout the bar. Designed for use in concrete reinforcement, rebar increases the tensile strength of concrete structures. ASTM A615 is the standard specification for deformed and plain carbon steel bars for concrete reinforcement.
