We will offer a suitable solution to you. However, if you are still confused, please talk with us about the use purposes and use environment. These details will help us to provide you with the latest price as soon as possible. If you have special requirements, such as packaging, zinc coating thickness, seismic standards, etc., please let us know. How many pieces or tons do you need for your projects? Generally, the order quantity will directly influence the price. Also, it is very crucial to determine the diameter.Ĥ. Please confirm the grade, which indicates the minimum yield strength. According to the material, there are carbon steel reinforcement bars (black steel rebar) galvanized steel rebars stainless steel reinforcement bars epoxy-coated rebars.Ģ. You can find different types of reinforcement bars on the market. Of course, you can also inform us of the rebar codes you required.ġ. If you want reinforcing bar price, you need to confirm some basic information: material, grade, diameter, quantity, and your special requirements. So US bar size #3 means 3/8 inch, which is about 9.53 mm (3/8*25.4 mm).Ĭanadian Steel Rebar Size Chart Metric bar sizeĮuropean Steel Rebar Size Chart Metric bar size Note: US bar sizes use the diameter in units of 1⁄8 inch. Note: The weight is calculated by the carbon steel density of 7.85 kg/m³. Chinese Steel Rebar Size Chart Nominal diameter (mm) Gradeīelow are the sizes and weight charts according to Chinese rebar size, US size, Canadian sizes, and European size. Below is a table showing the common grades. And Grade 60 is the most popular rebar grade in US construction. Under ASTM A615, Grade 40 is only in sizes #3 to #6. The most common grades are Grade 40, 60, and 75. For example, Grade 40 rebar has a minimum yield strength of 40 ksi, which is equal to 300 Mpa. In US use, the steel rebar grade shows the minimum yield strength in ksi (1000 psi). HRB500 (Grade IV) is 12 mm in diameter, and it is widely used in large-scale pre-stressed construction, such as roof, crane beam, etc. It is often used in special buildings, such as villas. HRB400 (Grade Ⅲ) is similar to HRB 335, but it is of higher strength and higher price. It is commonly used for beams, columns, shear walls in large and medium-sized concrete structures, such as bridges, dams, houses, etc. HRB335 (Grade Ⅱ) is deformed steel bar, with a diameter of 12-25 mm. It is often used to make stirrups, wall reinforcement, and so on. HPB300 (Grade Ⅰ) is plain steel rebar, with a diameter of 6-12 mm. For example, HRB400 is hot-rolled ribbed steel bars, and its standard yield strength is 400MPa. The number stands for the minimum yield strength. Besides, “F” means fine grains while “E” stands for seismic (Earthquake) ductility. Here “H” stands for hot-rolled, “R” is for ribbed steel bar, “P” is for plain round bar, and “B” is short for bars. The common grades of hot rolled ribbed bars are HRB400, HRBF400, HRB400E, HRBF400E, HRB500, HRBF500, HRB500E, HRB600. The hot rolled steel bar is divided into plain round bar (HPB300) and ribbed bar. According to the production process, we have hot-rolled steel bar (H) and cold rolled steel bar (C). Reinforcement bar grade in China is subject to the requirements of Chinese Standards GB1499.2-2018. Besides, the use of a grade indicates the minimum yield strength. And the grade designation varies by country. That’s why rebar couplers are getting more attention.Rebar (reinforcing bar) is available in different grades and specifications. PINKBAR+ Fiberglas Rebar by Owens Corning Infrastructure Solutions is enabling Glas-Powered Concrete. Concrete professionals add rebar or mesh to concrete in order to increase the tensile strength of the concrete and prevent cracking that could, for example, ruin or. Owens Corning PINKBAR+ 0.5-in x 10-ft Pink Fiberglass 4 Rebar. #NUMBER 15 REBAR CRACK#This is why concrete tends to crack over time. The use of higher-strength concretes permits shorter lap lengths. For concrete that is between 3000 to 6000 psi (or 20 to 40 MPa), then its tensile strength would be 300 to 700 psi (or 4 to 5 MPa). #NUMBER 15 REBAR CODE#The bar sizes from number 8 to number 11 with yields of 60 or 75 ksi are used in current design practice for structural framing And the accepted concrete strengths by code vary from 8000 to 12,000 psi. RCC framed structural buildings nowadays are being built to 100 stories and more. In projects with small bar sizes such as of number 6 or number 8, relatively low yield stress in steel, and building heights of 15 stories or less, lap splices have performed well over a long time. In that case, we need more pieces of steel bars that must be spliced together to achieve the desired length. Splicing is required when the required length of a bar suppresses the available length of steel rod, or the rod may be too long to be delivered conveniently.įor example, suppose we need to build a 30 m long building, but there is not a single 30 m long bar available in the market. In almost all RCC structures, rebars need to be spliced.
