Usage and Applications

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.

Q:What is the maximum tensile force of 25 thread steel?
The maximum tensile force is the first to know that the thread steel belongs to several grades of steel; the tensile strength is x, and the cross sectional area is the maximum tensile force.Tensile strength of thread steel of 25 diameter = tensile strength of the grade steel, x, sectional area =41000, Newton, ~61000, Newton=4100kgf~6100kgf.
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 national standard of thread steel No. 8?
Rebar national standard: transverse rib nominal spacing shall not be greater than 0.7 times the nominal diameter of steel, the cross rib side and the steel surface of the angle of alpha may not be less than 45 degrees. When the steel nominal diameter less than 12mm, the relative rib area should not be less than 0.055, the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060, the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065. Therefore, the nominal diameter of rebar No. 8 national standard steel bar relative rib area shall not be less than 0.055mm
Q:What is hot rolled coil? Hot rolled coil relative to thread steel and other steel, is not considered a higher point?
The thread steel is a long piece of steel pulled out at a certain temperature.There is no high or no advanced problem between the two.
Q:What specifications should be used for the three - step steel electroslag pressure welding electrode?
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.
Q:Are thread steels of coarse steel?
Thread steel does not belong to coarse steel, rough is shaped steel, fine is wire.
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:Thread steel is embroidered after rain. Can it be used as reinforcing steel?
Thread steel after rain, raw embroidery, but also used as steel, with rust done before the line.
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:Can the end of the steel bar be inserted by the steel bar?
Chemical method refers to the construction method of chemical anchorage adhesive anchorage, referred to as Zhijin, also called a bar connection technology building aseismic reinforcement project of a reinforced anchorage structure using rubber lock grip force effect, is the best choice and reinforcement of heavy load fastening application structure of anchorage.
