Usage and Applications of ASTM, GB Standard Hot Rolled Deformed Steel Rebars:

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 ASTM, GB Standard Hot Rolled Deformed Steel Rebars:

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:Is cold-rolled ribbed steel bar thread steel?
Which is divided into cold rolled ribbed steel and hot rolled ribbed bar. Usually called hot rolled ribbed steel hot rolling thread steel or steel
Q:Is the theoretical weight of threaded steel and round steel the same?
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. 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:Are steel bars used more in high-rise buildings or steel?
The State advocates the use of new steel grades and designs responsive to national policies.Xingang are screw steel, screw thread steel with multiRound bars are often used in stirrups
Q:How to recognize high quality thread steel
Inferior steel due to poor production conditions, bulk, no metal signs, no quality guarantee. For safety reasons, we should not buy the inferior steel bars, or go to the direct agents of some famous brand manufacturers, so that the quality is guaranteed. Shandong hundred fertile Steel Pipe Co., Ltd. here recommends that users in the purchase of thread steel, must go to the formal steel business units to purchase, request steel quality certificate, and acceptance.
Q:12 how much is one ton of thread steel?
If it is hrb400e three grade rebar, then 12 of the meter price is 2.07 yuan; if it is hrb50 four grade rebar, that 12 of a meter price of 2.23 yuan.
Q:What is the sign of steel rebar
At present, China's iron and steel products implementation standards are national standards (GB, GB / T), industry standards (YB), local standards and enterprise standards
Q:What is the difference between the II and III grades of threaded steel?
Third grade rebar than ordinary II rebar strength increased about 20%, is designed for building construction of reinforced structure is developed, the yield strength of 400Mpa (grade HRB400), is the country to promote the use of excellent products.
Q:Excuse me, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer
Anything you say can be called steel bar, except steel wire. Round and round is a name, and wire coil, general line.
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:Why is the difference between left and right threads? What's the difference?
The design direction of rotation screw steel, steel and related crystal. Due to crystal dislocation, under the tensile stresses along a surface slip between the crystal, for single crystal, slip surface and tensile stress direction angle of about 45, at the same time, the crystal will around the stress-induced rotation axis. According to the characteristics of steel, the surface of the reinforcement design into a spiral shape, can effectively improve the strength of steel, save materials, reduce the weight of the building. Of course, there are combined with concrete between considerations.
