Product Description:

Bars of steel commonly used in construction, especially for reinforcing concrete structures such as driveways, 

foundations, walls, and columns. These bars come in different sizes and strength grades, and can be smooth 

or may include deformations that provide greater adhesion for concrete poured over the bars. When used in poured 

concrete, the bars are typically placed in a grid pattern, the concrete poured over them, and then readjusted to 

maintain the proper shape while the concrete sets. Steel rebar can be purchased from a number of manufacturers 

and is often found at construction retailers or large hardware stores

Most grades of steel used in rebar cannot accept welding; such as, to adjacent steel plates or as means to bind

single pieces of rebar together. However, special grades of rebar steel and welding rods make welding by expert 

welders possible.

To prevent workers from accidentally impaling themselves, the protruding ends of steel rebar are often bent over or 

covered with special plastic "mushroom" caps.

Q:4E DG 164 is a steel grade 3 steel, DG steel, E is what mean
4 means HRB400, that is, hardness.E stands for seismic reinforcement.DG is da-gang.16 is the diameter 16mm.
Q:What are the listed companies that produce wire rod and thread steel?
It is commonly known as steel hot rolled ribbed bar. 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. The thread steel is a kind of small section steel, mainly used for the skeleton of reinforced concrete building member, the raw material for producing thread steel, and the carbon billet is a carbon structural steel or low-alloy structural steel which is treated by calm melting.
Q:What is the difference between the material of steel thread and its use?
There are two kinds of thread classification methods:First, the geometric shapes are classified and classified according to the cross sectional shape of the ribs and the pitch of the ribs. For example, the British Standard (BS4449), the steel is classified into type I and type ii.Two is in the performance classification (grade), for example our country standard (G B1499), according to the strength level (yield / tensile strength) will be divided into 3 grades of thread steel;
Q:What is the difference between three - grade steel and other grades?
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.
Q:10 less than three rebar refers to the rebar?
A grade steel is round, without ribs, elongation is the advantage, of course, it also determines its strength is lower than grade three steel.
Q:What are the specifications of thread steel?
China's standard recommended nominal diameter of 6, 8, 10, 12, 16, 20, 25, 32, 40, 50mm thread steel series.The supply length is divided into two kinds: foot length and foot length.China's export screw length selection range is 6 ~ 12m,The selection length of Japanese thread steel is 3.5 ~ 10m;Domestic sales of domestic thread steel, if the contract does not specify requirements, usually fixed length of 9m, 12m two length.
Q:What's the difference between rebar and thread steel?
In construction, round bars and rebar are popular terms for different kinds of steel. There are five main differences between them:1. different shapes. The outer surface of the round steel is smooth; the outer surface of the spiral steel has a spiral rib.2. different production standards. In the current standard, round bar that HPB235 grade steel, and its production standards are "hot-rolled smooth steel reinforced concrete" (GB13013); rebar generally refers to HRB335 and HRB400 grade steel, its production standard is "the reinforcement of concrete hot rolled ribbed bar" (GB1499).
Q:What is the specific concept of thread steel through water and what is the difference?
Water cooling technology is used in the production of rebar, and the temperature of controlled cooling termination is higher than the recrystallization temperature of the material. If the temperature is obviously lower than the recrystallization temperature, the surface of the reinforcing steel is easy to form a thin layer of quenching and tempering structure. Quenching and tempering organization once formed, will undermine the strong cuby rebar and welding performance.
Q:Why does the steel thread have longitudinal ribs?
The main function of the longitudinal ribs is the force to improve the performance of the transverse ribs, the stress of support surface transverse rib in the longitudinal direction, reducing flange stress concentration, so as to improve the mechanical strength of the reinforced rib, deformation of bond between concrete and steel reinforced concrete, the collaborative work and better.The effect of the longitudinal ribs is indirect, which improves the mechanical properties of the transverse ribs and indirectly enhances the bond with the concrete.
Q:What's the difference between primary and two grade steel and three grade steel?
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.
