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:Why is thread steel thinner than crude?
Reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often appear to "project inspector", to replace the steel rib steel "Choulianghuanzhu", reduce the construction cost. In the design, because the members allowed to provide "stirrup stress support", the main role is to keep the shape and location of longitudinal reinforcement, steel strapping has a smooth surface, accurate positioning, therefore, in addition to longitudinal reinforcement, licensing round steel stirrups. The longitudinal reinforcement must be made of rib steel.
Q:JL32 is the finish thread heavy bar 32? What's the difference between normal and ordinary? What does the front JL32 mean?
Finishing rolling rebar diameter of JL32-- 32mm, 32 - screw steel hot rolled ribbed steel bars, the difference between the two: 1, ribbed bar is injected directly into the concrete, increase of steel concrete.
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?
As far as I know, the price of information may not be divided into "E" and "E", but there are mandatory requirements on the standard. It is estimated that the price will not be much different.
Q:What are the specifications of thread steel?
Specification requirements for threaded steel shall be specified in the import and export trade contract.Generally should include the standard grade (type code), the nominal diameter of steel, nominal weight (quality), the length of the specifications and the allowable difference between the above indicators.
Q:How to judge the quality of thread steel?
First of all, to see if there are rebar factory quality certificate and inspection report
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: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:How much is the weight of 6mm thread steel KG?
Rebar also depends on how many grades of steel can be used to determine the carrying capacity (tensile strength, design value). Grade two steel is 300 cow / square millimeter, grade three steel is 360 cow / square millimeter, grade four steel is 435 cow / square millimeter. Converted to 6mm steel, grade two steel is 847kg, grade three steel is 1017kg, grade four steel is 1229kg
Q:Is cold-rolled ribbed steel bar thread steel?
Cold rolled ribbed bars are threaded steel. Thread steel is traditionally called standard steel.
Q:Why is the earthing device forbidden to use thread steel instead of round steel as lap steel bar?
The mechanical strength of the steel thread is destroyed. Because the supporting point is only the ground, it is easy to cut the steel directly if the thread is not vertical. Therefore, we need to use angle iron, steel pipe or smooth steel round bar.
