Usage and Applications of 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 Deformed Steel Bar:

Packaging Detail: products are packed in bundle and then shipped by container or bulk vessel, deformed bar is usually naked strapping delivery, when storing, please pay attention to moisture proof. The performance of rust will produce adverse effect.

Each bundle weight: 2-3MT, or as required

Payment term: TT or L/C

Delivery Detail: within 45 days after received advanced payment or LC.

Label: to be specified by customer, generally, each bundle has 1-2 labels

Trade terms: FOB, CFR, CIF

Q:What is the difference between rebar and round steel?
The difference between Jinzhong rebar and round bars: we can from the surface can be seen from the thread steel and round steel bar, we identify the next time don't let yourself do not understand the trouble, do not know how the difference.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Longitudinal tie rod. Longitudinal seam usually has longitudinal contraction joint and longitudinal construction joint two kinds, two kinds of longitudinal joints should be provided with tie rod. The bar shall be designed with the length of the threaded steel to ensure the bond between it and the concrete, and the diameter and spacing of the tie rod shall also be guaranteed. Thus, the tie rod can not provide enough tensile force, and when the concrete faceplate is contracted, the longitudinal joint is pulled apart to form a crack.
Q:Are thread steels of coarse steel?
The thread steel is not coarse steel and the thread steel belongs to the steel. Rough steel refers to the billet after casting steel. The billet has been rolled into various shapes of steel, including plates, profiles, tubes and so on.
Q:Excuse me, Shagang steel steel, what is the sign of
The two is the performance of classification (class), for example, China's current implementation of standards, (G B1499.2-2007) for steel wire for 1499.1-2008), according to the strength (tensile strength yield point / steel) will be divided into 3 levels; the Japanese industrial standard (JI SG3112), according to the comprehensive performance of the steel branch for the 5 species; the British Standard (BS4461), also provides some level of performance test of thread steel. In addition, the thread steel can be classified according to the use, such as reinforced concrete, ordinary steel bars and reinforced concrete bars for heat treatment.
Q:What is the difference between the II and III grades of threaded steel?
Compared with traditional II grade steel, the characteristics are as follows:1, high corrosion resistance, can be a large number of security reserves.2. In the chemical composition, because of the low carbon equivalent of the new third grade steel, the welding performance is good.3, high strength ratio, meet the seismic performance requirements. Particularly suitable for high-rise buildings and high seismic performance requirements of the project.4, cold bending performance is good, can be repeatedly bent, more in line with and meet the construction requirements of the construction.5, because of the high strength, can reduce the use of steel, effectively solve the problem of reinforcing steel bars too close, easy to concrete pouring. At the same time, it also reduces the cost of steel transportation and on-site processing.
Q:What does "4E" mean on the rebar?
The meaning of 4E on the rebar is HRB400 seismic reinforcement (HRB400e). 4 is HRB400 (formerly known as grade 3 steel), e is earthquake's e, meaning earthquake resistance. The steel bars marked with e have reached the standard of "anti-seismic" steel issued by the state.
Q:What does "4esg25" mean on thread steel?
The brand of steel is expressed in terms of Arabia numerals or Arabia numerals plus English letters. HRB335, HRB400 and HRB500 are represented by 3, 4 and 5, respectively. HRBF335, HRBF400 and HRBF500 are represented by C3, C4 and C5 respectively. The name of the factory is expressed in Chinese phonetic prefix. Nominal diameter mm Arabia digital representation.
Q:How to distinguish the quality of thread steel?
Inferior steel has no metallic luster and is pale red or similar to pig iron. The reason is two point two. Its billet is adobe. 2, the quality of stainless steel rolling temperature is not standard, their steel temperature is through visual inspection, this can not be rolled according to the provisions of the austenitic region, the performance of steel can not meet the standard.
Q:Why is the threaded steel thread?
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:Is the steel thread stainless steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
