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:The difference between rebar and crescent
Rebar -- steel used in concrete structures with a generally rounded cross section and ribbed surface.Longitudinal ribs -- uniform continuous ribs parallel to the axis of the steel bar -- other ribs not parallel to the axis of the reinforcement.The longitudinal section of crescent ribbed bars -- transverse rib reinforced crescent, and does not intersect with longitudinal ribs.
Q:How to calculate the theory of steel thread?
Thread: a spirally curved, continuous raised part with a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
Q:How to distinguish the quality of thread steel?
Inferior steel thin and thin, often appear inadequate discontent, because manufacturers in order to achieve large negative tolerance, finished products before a few of the pressure reduction is too large, iron type is small, filled with dissatisfaction.
Q:16 meters of thread steel, how many meters?
Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:Why can not the finish thread steel be welded?
Finish rolling thread steel can be directly connected with sleeve, and do not use wire; you want to weld can also, it is estimated that the user does not require welding, welding prone to appear strong phenomenon. If welding is used, buy the finish steel, which is more expensive than the other threads of the performance.
Q:Like a steel rebar and wire spiral, is the same? What's the difference?
Generally, the thickness of the plane is about 1/30 of the span, and the value is more than 80. The higher the mark of commodity concrete, the higher the price, the different areas are, the average is about 350.
Q:How much is the weight of 6mm thread steel KG?
Multiple objects can be hung, not only to see the hook itself, the bearing strength is not enough, the hook is nothing, even with the bearing down together is possible.
Q:What is the diameter of the cross section of the threaded steel?
There are many ways to measure diameter. Different methods are adopted according to different precision requirements,The simplest method is to use the scale directly, and the longest line through the section is the diameter. This method has the lowest precision
Q:What are the main uses of threaded steel?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. Steel is usually used for reinforced concrete, its role is to increase the friction fringe, the rebar and concrete secant integrally formed together, tic phenomenon can not occur in the role of external force, improve the strength of concrete.
Q:What does "4EDT6" mean on thread steel?
There are many kinds of steel. It is a kind of long strip steel with definite cross section shape and size. It is divided into two kinds of simple and complex sections according to their cross section shapes. The former includes round steel, Fang Gang, flat steel, six angles and angles; the latter include rail, I-beam, channel steel, window frame steel and profiled steel. Small diameter steel wire in 6.5-9.0mm is called wire rod.
