Usage and Applications of GB Standard HRB400 Steel Deformed Bar 22mm/25mm:


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 GB Standard HRB400 Steel Deformed Bar 22mm/25mm:

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.

Q:14 screw steel 1 meters multiple?
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 will be divided into thread steel 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 does "4EDT6" mean on thread steel?
It is a long strip of steel with a hollow cross section. It can be divided into round tube, square tube, hexagonal tube and all kinds of special-shaped section steel tube according to its sectional shape. According to the different processing technology, seamless steel pipe and welded pipe can be divided into two categories.
Q:How many patterns are there in threaded steel?
Rebar is ribbed steel, ribbed steel, including rebar. A ribbed steel bar with 2 longitudinal ribs and uniformly distributed ribs along the length. The transverse rib shape is helical, herringbone, crescent 3. Because of the function of rib, it has better bonding ability with concrete, so it can bear the effect of external force better.
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
Now Tianjin Tiantai into 12 of the price is 3900 yuan a ton, 16 tons of steel a price is 3850 yuan. 12 of thread steel is 50 yuan more expensive than 16 thread steel.
Q:What is the manufacturing process of the hot rolled thread steel production line?
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. Ltd. to provide thread steel weight: diameter * * outer diameter theory 0.00617=kg/m theory and 6.50.260 steel manufacturers specifications Jiuzheng 8.00.395 Jiuzheng steel 100.617 steel 120.888 steel 141.21 nine nine nine nine nine steel 161.58 steel 182 steel 202.47 steel 222.98 steel 253.85 nine nine nine nine nine steel 284.83 steel 326.31 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:What does "4E" mean on the rebar?
Hrb400e refers to three earthquake resistant steel bars. Compared with the ordinary reinforced phase, the biggest advantage is that the tensile strength and elongation are relatively large, for example, the tensile strength of common grade HRB400 three reinforcement requirements of more than 400 MPa; if hrb400e is aseismic reinforcement, the tensile strength is more than 550MPa.
Q:What does it mean to have 22 4GJ on the threaded steel?
4GJ22 these are the basic information of reinforcement, equivalent to the identity card information. The steel plant on behalf of grade four steel (HRB500) GJ is Hangzhou iron and then the nominal diameter is 22.
Q:How to judge the quality of thread steel?
Appearance check the necking fracture, peeling, oil pollution, damage, deformation, diameter error, third is the best for the test, according to the provisions of the current "reinforced concrete hot-rolled ribbed bar" GB1499 current national sample sent to the laboratory test, the sample collected for tests of mechanical properties, such as more than three are qualified, steel is good the!
Q:Is thread steel rod or wire?
10mm below can also be transferred to the wire, 10mm or more to the bar. Wire and rod are attributed to the bar, so there is no distinction between strictly.
