Usage and Applications of GB Standard HRB400 Steel Deformed Bar 28mm/32mm:

 

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:Excuse me, Shagang steel steel, what is the sign of
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:What is the national standard of thread steel No. 8?
Thread steel specifications: generally including the standard grade (type code), steel nominal diameter, nominal weight (quality), the length of the specifications and the allowable difference between the above indicators. China's standard recommended nominal diameter of 6, 8, 10, 12, 16, 20, 25, 32, 40, 50mm thread steel series.
Q:What is the difference between the actual weight and the actual weight of the steel thread?
Is the difference between the work and the theory of weight. General steel factory, have weight difference, unlike canned beverage, not so accurate, this is called "bad" or "inferior". But the mills are not stupid, only under the poor, is not Quejinshaoliang, with a significant difference (such as standard 100KG, he will give you a 110KG).
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:Thread steel 20*9 one is 2.001T. How many pieces of this one?
Thread steel 20*9, one is 2.001T, and this one has about 90. Thread steel 20*9, parameter is 20mm in diameter, length is 9m.
Q:How much is the weight of 6mm thread steel KG?
The two grade steel is 847kg, the three grade steel is 1017kg, and the four grade steel is 1229kg
Q:Why can't grounding steel be used?
When the thread steel is grounded, the contact with the soil is not dense, and the grounding resistance value is increased
Q:Is the steel thread stainless steel?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; the corrosion (acid, alkali, salt and other chemical etching) steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:Difference between round bar and threaded steel in use
Because the surface has a thread shape, it can increase the firm bond with the concrete. The longitudinal reinforcement and stirrups shall be used preferentially in the concrete members.
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.
