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:

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:What is the specific concept of thread steel through water and what is the difference?
Most of the thread steel is subjected to self - tempering after water cooling, and the tempered bainite is obtained. The advantage is that the strength will be better; the disadvantage is that after rolling through water, the surface oxide film of steel is destroyed, rust is sure
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:Is the tie bar used for the longitudinal joint of cement concrete pavement threaded or smooth? Where is the dowel bar for the transverse joint construction?
Dowel arm for transverse construction joint. The transverse construction dowel bar is applied with a light circle and half coated with asphalt, allowing sliding. In practical application, the construction units are convenient for drawing, often use thread steel, and do not apply asphalt. The concrete pouring time on both sides of the construction joint is different, the contraction during the condensation process is not synchronous, and the dowel bar can not be stretched and formed a weak link. Cracks occur at this weak point when concrete slabs contract under loads or natural factors.
Q:What is the national standard of thread steel No. 8?
Steel is known as hot rolled ribbed bar. The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required.
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:Two grade steel and three grade steel difference, the construction of the use of thread steel in general how to use the level?
According to the difference of prestressing strength, the trend is that the strength is higher and higher. The quantity of grade two steel has been replaced by grade three steel, and this year there are many 400E resistant steel
Q:Why is the price of screw steel affected by iron ore and coal?
Just now the manufacturing needs to consume iron ore and gas energy, the cost goes up, the price certainly changes
Q:Does the grade three thread steel with "E" have the same information price as the ordinary three grade thread steel? Is there a big difference?
Hello, with E thread steel is seismic rebar, without E is the common thread steel, general seismic thread with E was higher than that of ordinary steel prices, the price difference between 50 and 100 yuan, according to the specific market situation.
Q:Are rebar bars = rebar?
Rebar is only one of the reinforcing bars, and the reinforcing bars used in the construction site are distinguished from the appearance. They are mainly round steel (round steel bars) and plain steel (the appearance has lines, and the steel bars are divided into two kinds: thread and crescent).
Q:Why does the steel thread have longitudinal ribs?
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.
