Product Description:

Rebar has ridges that bind it mechanically to the concrete with friction, it can still be pulled out of the concrete 

under high stresses, an occurrence that often precedes a larger-scale collapse of the structure. To prevent such 

a failure, rebar is either deeply embedded into adjacent structural members, or bent and hooked at the ends to lock

it around the concrete and other rebars. This first approach increases the friction locking the bar into place while the 

second makes use of the high compressive strength of concrete.

Q:How to judge the quality of thread steel?
Sampling sample. Do tensile, bending, and impact tests.
Q:What is the national standard of thread steel No. 8?
Rebar national standard: transverse rib nominal spacing shall not be greater than 0.7 times the nominal diameter of steel, the cross rib side and the steel surface of the angle of alpha may not be less than 45 degrees. When the steel nominal diameter less than 12mm, the relative rib area should not be less than 0.055, the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060, the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065. Therefore, the nominal diameter of rebar No. 8 national standard steel bar relative rib area shall not be less than 0.055mm
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:What's the difference between finish rolling thread steel and ordinary thread steel?
To say the difference between the new bridge finish rolling thread steel and ordinary thread steel main difference between finish rolling thread steel: mainly used for high strength, difference is mainly different strength, chemical composition is not the same:Finish rolling thread steel is prestressed steel, and its strength is higher than ordinary thread steel.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Among them, 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:Is the theoretical weight of threaded steel and round steel the same?
The difference between such rebar and round bars with longitudinal ribs and transverse rib surface, usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution.
Q:Why do stirrups have thread stirrups and round bars? When are they used?
Your question is actually related to steel and concrete work of a force of synergy in the reinforced concrete structure, steel usually is in tension, in order to ensure the reinforcement force can be well transferred to concrete, so as not to slip, we put the steel processing into whorl ribbed or other rib the shape, its purpose is to increase the adhesion between steel and concrete. Round steel is usually used in lower grade, smaller diameter reinforced steel, mainly because of its low strength, without adding ribs, round bar and concrete bonding between the relay can ensure that its strength is very good play. Therefore, steel bars are mainly used in places where the force is not large and the calculation of the reinforcement is very small.
Q:Why can not the finish thread steel be welded?
This is generally superior to alloy steel. Carbon content is relatively high, poor weldability, welding conditions are very demanding, but also produce high temperature welding, it is easy to destroy the original material performance. So, under normal circumstances, on-site welding is not allowed.
Q:16 meters of thread steel, how many meters?
Thread steel factory specifications, part thickness is generally 9m or 12m root
Q:The difference between round face and round bar steel on concrete
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 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.
