Usage and Applications of Hot-Rolled HRB400 Reinforced Deformed Steel Bar

Deformed bar is widely used in buildings, bridges, roads and other engineering construction. Big to highways, railways, bridges, culverts, tunnels, public facilities such as flood control, dam, small to housing construction, beam, column, wall and the foundation of the plate, deformed bar is an integral structure material. With the development of world economy  and the vigorous development of infrastructure construction, real estate, the demand for deformed bar will be larger and larger..


Packaging & Delivery of Hot-Rolled HRB400 Reinforced Deformed Steel Bar

Q:Do l 8, three grade steel have discs?
Yes, but because of the higher grade of the three screw thread, they are straight bars. It's not necessary to use grade three for 8 mm.
Q:What is thread steel for?
The difference between three grade steel and two grade steel can be divided into the following aspects:1, different grades of steel (chemical composition is different). HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;2, strength is different, HRB335 grade steel tensile and compressive design strength is 300MPa, HRB400 grade steel tensile and compressive design strength is 360MPa.3, because of the chemical composition of steel and the ultimate strength of different, so in toughness, cold bending, fatigue and other properties are also different.
Q:Is the tie bar used for the longitudinal joint of cement concrete pavement threaded or smooth? Where is the dowel bar for the transverse joint construction?
Please note that the recommended answer is really! Do not know the professional knowledge, do not find a copy and paste to harm people! The tie bar is a screw bar, and the tie bar is a device for balance. The steel bar can be used to connect with the concrete! The dowel bar, as the name suggests, is the transfer of force, must use light round steel bar, when powerful, light round steel and concrete have movable interface, can conduction force!
Q:16 meters of thread steel, how many meters?
Thread steel factory specifications, part thickness is generally 9m or 12m root
Q:In the concrete floor, how big can the steel bar be replaced by the big screw steel? How to convert?
The strength of the reinforcement to be replaced must be greater than or equal to the original strength of the reinforcement. The tensile strength of the original reinforcement, the square of the diameter * the tensile design strength / the diameter of the reinforcement to be replaced by the square *, the tensile design strength.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:The difference between wire and thread steel, wire and thread steel difference knowledge
The surface of the ribbed steel is ribbed, the ordinary hot-rolled bar is HRB, and the fine grained hot rolled steel bar is HRBF. The main use of thread steel: widely used in housing, bridges, roads and other civil engineering construction. Rebar main origin: steel manufacturers in China are mainly distributed in the north and northeast, North China, Tang Gang, such as Shougang steel, bearing steel, such as the northeast northwest Taiwan, Fushun Steel, these two regions accounted for more than 50% of the total output of thread steel.
Q:Why can't grounding steel be used?
In addition, the skin effect of the current, the thread of the threaded steel surface, is equivalent to the addition of an inductance, which is detrimental to the rapid unloading of the high-frequency lightning current
Q:Cold drawn steel wire is a round bar or thread steel in Construction Engineering
Cold drawn steel wire should be the same as round steel and thread steel! Their forming process and the meaning of the place used are different, and the quota is also different, cold drawn steel wire is cold drawn steel wire, strictly speaking, there is no mix together.
Q:Why does the steel thread have longitudinal ribs?
Thread steel is inaccurate, commonly known as standard "deformed steel bars"". Hot rolled ribbed steel production in China, the surface usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution, when the longitudinal section transverse rib crescent, and does not intersect with the longitudinal ribs, called crescent rib reinforced; when the longitudinal section is equal to the height, and with the intersection of longitudinal ribs, said for high ribbed bar. The second and third grade ribbed bars commonly used in engineering usually adopt the crescent rib surface shape.Similar to the screw thread, our country did not produce, it is said that there is such a shape abroad.If it is necessary to say that it is possible to strengthen the tensile and shear strength, because after all, the longitudinal rib expands a little of the cross section of the steel bar. But this is not the purpose of rolling longitudinal rib, the purpose of longitudinal rib is to improve the mechanical performance of the transverse rib.
