HPB300/HRB335 Reinforcement Rebar
According to the production process, there are hot rolled steel bars (H) and cold rolled steel bars (C). Hot-rolled steel bars are divided into smooth round steel bars (HPB300) and ribbed steel bars. The common brands of hot rolled ribbed steel bars are HRB400, HRBF400, HRB400E, HRBF400E, HRB500, HRBF500, HRB500E and HRB600. HPB300 (Grade I) is a common steel bar with a diameter of 6-12mm, commonly used in the production of stirrup, wall reinforcement, etc.
HRB335 (Grade II) is a threaded steel with a diameter of 12-25mm, commonly used in bridges, dams, houses and other large and medium-sized concrete structures in the beam, column, shear wall. HRB400 (Grade III) is similar to HRB 335, but is stronger and more expensive. It is often used in special buildings such as villas. HRB500 (Grade IV) is widely used in large prestressed buildings, such as roofs, crane beams, etc.

RebarOrdinary carbon structural steel is also called ordinary carbon steel. The carbon content is 0.06-0.22%, with less than 0.25% being the most commonly used. Belonging to low carbon steel, each metal grade represents the lowest yield point of the steel when the thickness is less than 16mm.![HPB300/HRB335 Reinforcement Rebar]( "HPB300/HRB335 Reinforcement Rebar")
HPB300/HRB335 Reinforcement RebarHPB300 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.![X-Steel-Rebar HRB500]( "X-Steel-Rebar HRB500")
X-Steel-Rebar HRB500Technological Process:
Deformed steel bar is the common name of hot-rolled ribbed steel bar. The grade of ordinary hot-rolled steel bar consists of the minimum yield point of HRB and grade. H, R and B are the first letters of Hotrolled,Ribbed and Bars.![HRB400/HRB400E Deformed Steel Rebar]( "HRB400/HRB400E Deformed Steel Rebar")
HRB400/HRB400E Deformed Steel RebarHRB400 is a steel reinforcement material with high strength and good plasticity. HR stands for "hot rolling", which essentially refers to the heating and rolling process of steel bars in the production process. B represents that its yield strength is 400 megapascals (MPa) higher than that of ordinary carbon steel.![ASTM A615 Concrete Rebar Grade 40]( "ASTM A615 Concrete Rebar Grade 40")
ASTM A615 Concrete Rebar Grade 40A615 grade 40 steel adds the most benefit when building materials must hold concrete in compression. Strength is one of the differentiators for these two rebar grades. The minimum tensile strength for A615 grade 40 steel is 70.05 ksi. It has a minimum yield strength of 40 ksi.![ASTM A615 Reinforcing Bar Grade 60]( "ASTM A615 Reinforcing Bar Grade 60")
ASTM A615 Reinforcing Bar Grade 60ASTM A615 is a deformed steel standard categorized under American standards. These are generally available in diameter between 9.5 mm and 43 mm, and length between 6 m and 12 m. Generally, the steel bars that fall under this standard are under deformed or plain carbon steel.![BS4449 Steel Reinforcement Rebar]( "BS4449 Steel Reinforcement Rebar")
BS4449 Steel Reinforcement RebarBS4449 is yet another deformed steel bar standard. It is also differentiated as per European standards. When it comes to manufacturing, the steel bars falling in this standard are also hot rolled, which means that they are also used for general purposes, i.e. in common construction projects.![HRB500/HRB500E Deformed Steel Rebar]( "HRB500/HRB500E Deformed Steel Rebar")
HRB500/HRB500E Deformed Steel RebarHRB500 steel reinforcement refers to a commonly used steel material in concrete structures, which has certain strength and toughness, and can effectively enhance the bearing capacity and tensile performance of concrete. Steel reinforcement plays an important role in construction.![HRB600 High Strength Hot Rolled Reinforced Bar]( "HRB600 High Strength Hot Rolled Reinforced Bar")
HRB600 High Strength Hot Rolled Reinforced BarHRB600 steel bar is a new type of hot-rolled ribbed steel bar with high strength and good ductility. The use of HRB600 steel bar in engineering presents advantages such as saving steel bar usage and facilitating steel bar layout.![B500A/B500B/B500C Rebar]( "B500A/B500B/B500C Rebar")
B500A/B500B/B500C RebarB500A grade steel is usually used for steel mesh products while B500B grade steel is used for steel bars. B500C steel is rarely required, and it is always worthwhile for structural engineers to check whether B500B grade steel can be used instead of B500C, because B500C usually has a significant cost overhead.
