Cold Rolled Techniques

Yield Point: 545-565mpa

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:How to calculate the theoretical elongation of finishing thread steel?
The grade of prestressed concrete rebar is defined by the yield strength. The code is PHB, plus the minimum value of the specified yield strength. P, H and B are English first letters of Prestressing, Hot and Bars respectively. For example: PHB830 represents a steel bar with a minimum yield strength of 830MPa.
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?
Please note that the recommended answer is really! Do not know the professional knowledge, do not find a copy and paste to harm people! The tie bar is a screw bar, and the tie bar is a device for balance. The steel bar can be used to connect with the concrete! The dowel bar, as the name suggests, is the transfer of force, must use light round steel bar, when powerful, light round steel and concrete have movable interface, can conduction force!
Q:Which is more expensive, rebar or round steel? Which is your business opportunity, such as thread steel and round bar?
The two thread steel and round steel, which will be more expensive, steel and round steel prices now are soaring, steel prices per ton in 4300 yuan / ton, quality steel grade three Beijing qianshengcheng price is in 3950-4200 yuan / ton.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Wire is a wire, usually refers to the use of "high speed non-twist wire rod rolling mill, ordinary common low carbon steel, hot-rolled wire torsion free cooling (ZBH4403-88) and the high quality carbon steel, hot-rolled wire rod without torsion cold control (ZBH44002-88).
Q:Two grade steel and three grade steel difference, the construction of the use of thread steel in general how to use the level?
The difference is mainly in strength. The higher the grade, the greater the tensile strength.
Q:Difference between round bar and threaded steel in use
Because steel for low alloy steel, its price is higher than that of low carbon steel, or construction units, design units, often on the general civil construction of the "practical" point of view, reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often bribed "project inspector after" to replace "Choulianghuanzhu rib steel bar, reduce the construction cost.
Q:What is thread steel for?
Three rebar is the new standard name for HRB400 steel, three steel for the old, as a kind of hot rolled ribbed bar. In construction, three - grade rebar is called the past.
Q:Are rebar bars = rebar?
Generally speaking (not absolute circle) steel is usually made of plate steel as the main form of packing, while threads are usually packed in straight strips.Turn left and turn right |
Q:Why is the threaded steel thread?
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required.
Q:Why is round bar more expensive than thread steel?
Threaded steel should be used in the construction field, there are generally two, three grade steel, grade HRB335, HRB400 also has four grades, HRB500 thread steel.
