Usage and Applications of HRB400 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 HRB400 Deformed Steel Bar:

Q:How is thread steel made?
The billets used in continuous small mills are generally continuous billets, the length of which is usually 130~160mm, the length is about 6~12 meters, and the billets are 1.5~3 tons in weight. The rolling line is mostly flat interchange arrangement to realize all round rolling without torsion. According to different billet specifications and finished sizes, there are 18, 20, 22 and 24 small mills, 18 of which are mainstream. The use of bar rolling reheating furnace, high pressure water descaling, in addition to the new technology of low-temperature rolling, endless rolling, rolling, rolling development to adapt and improve the precision of rolling billet, rolling mill is mainly to improve the accuracy and speed (up to 18m/s). Product specifications are generally phi 10-40mm, Phi Phi 6-32mm or 12-50mm. The steel grades produced are low, medium and high carbon steels and low-alloy steels, which are widely needed in the market. The maximum rolling speed is 18m/s. The production process is as follows:Reheating furnace, roughing mill, rolling mill, rolling mill, water cooling device, cooling bed, cold shear, automatic counting device, bundling machine, unloading bench is calculated from the Shanghai kuanli Steel Co.

Q:How many patterns are there in threaded steel?
There are two kinds of classification methods commonly used types of thread steel: one is to shape classification, according to different space shapes and transverse rib rib for classification or type, such as the British Standard (BS4449), the thread steel is divided into type I and type ii. This classification mainly reflects the tightening performance of the threaded steel. The two is the performance of classification (class), such as China's standard (G B1499), 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 steel will be divided into 5 categories; the British Standard (BS4461) also, certain provisions of the grades of steel performance test thread. 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. Main uses: widely used in housing, bridges, roads and other civil engineering construction.
Q:8 mm thread steel, how much is a bundle?
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:Can the end of the steel bar be inserted by the steel bar?
Through the bar Rachel reinforced with steel end can not hook, because the adhesive force can ensure the effective reinforcement and anchorage on ground, so there is no need to add a hook.
Q:What is the difference between the material of steel thread and its use?
The grade of thread steel is composed of the minimum value of the yield point of HRB and 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 HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
Q:What's the difference between finish rolling thread steel and ordinary thread steel?
The rebar used in prestressed concrete is a kind of bar with big diameter, high strength and high dimension precision, which is rolled with an external thread on the whole reinforcing bar. The steel bar is screwed at any cross section with a connector with an internal thread to connect or screw on the threaded nut for anchoring.
Q:Now, the two project is to use rebar or rebar?

Q:Why is thread steel thinner than crude?
Thread steel is used for the construction of reinforced concrete facilities, his material is generally low alloy steel grades is generally 16Mn (16 Mn low-alloy steel), or 45 carbon just, their yield strength is above 350Mpa, tensile strength 500Mpa, low carbon steel round steel than ordinary much higher (after heat treatment of the steel strength than low carbon steel nearly twice as high or higher)
Q:What are the main uses of threaded steel?
The difference between round bar and round bar is that the surface has longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs uniformly distributed along the length direction.
Q:Why is round bar more expensive than thread steel?
Steel is divided by tolerance standard of gb. You say there is no comparable price between round bar and screw thread. You can't use round bar as thread steel or thread as round bar!
