Product Description:

Reinforcing bar (Rebar) refers to the use of reinforced concrete and prestressed concrete with steel, its cross section is round, sometimes for the square with rounded corners. Including light round bar, ribbed steel bar, torsion bar. Reinforced concrete with steel bar is refers to the reinforced concrete reinforcement with straight or plate of strip steel, its appearance is divided into two kinds, light round steel and deformed steel delivery status for the straight bar and wire rod in two. Light round bar is really a small round steel and ordinary low carbon steel wire rod. Deformation is surface ribbed steel bar, usually with 2 longitudinal and cross rib of uniform distribution along the length direction. The appearance of cross rib is spiral, chevron, crescent 3 kinds. With nominal diameter mm number representation. Equals the nominal diameter is equal to the cross section deformation of reinforced light round bar nominal diameter. Reinforcement of nominal diameter is 8-50 mm, recommends to the diameter of 8, 12, 16, 20, 25, 32 and 40 mm. Steel grade: 20 mnsi, 20 mnsi MNV, 25, BS20MnSi. Rebar in concrete main tensile stress. Deformed bars as a result of the action of rib, and concrete have larger bonding ability, thus better able to withstand the role of external force. Steel is widely used in various building structures. Especially large, heavy, light thin wall and high-rise building structure.

Steel processing, steel processing to table and design review, check the material list for errors and omissions, for each steel bar to press

Material list to check whether meet the requirements, after these two checks, then press the material list sent out samples, trial production of qualified rear can batch production, processing and good reinforcement to neatly stacked in order.

Construction such as the need to be reinforced by substitution, must fully understand the design intent and substitution material performance, strictly abide by the current design code of reinforced concrete rules, not to area such as the substitution of low strength of high strength steel reinforcement. Any important parts of a reinforced substitution, shall agree with the consent of party a, design unit, and have a written notice shall be substitution.

(1) the steel surface should be clean, sticky oil, dirt, rust must be cleaned before use, can be combined with cold-drawn rust removal process.

(2) reinforced straightening, usable mechanical or manual straightening. After straightening of steel can not have local small bending, die bending, wavy, its surface scars should not be made of steel decreases by 5%.

(3) the steel bar cutting should be according to the number, diameter, length and quantity, the length is tie-in, first cutting long expected, by cutting short expected to reduce short head, and shorten the steel to save steel.

(4) steel hook or bend:

1) steel hook. There are three kinds of forms, respectively semicircle hook, hook and hook. After bending, bend endothelial contraction, skin

Extension, axis length is constant, bend arc formation, size is greater than the baiting size after bending, bending modifier should be considered.

Reinforced bending diameter of 2.5 d heart, straight part for 3 d. Steel hook increase the length of the theoretical calculation value: counter rotating round hook is 6.25 d, the straight

Hook is 3.5 d, the hook is 4.9 d.

(2) the bending of steel. Middle bending diameter D bend, not less than five times the diameter of the reinforcing steel bar.

(3) the stirrup. Stirrups should be done at the end of the hook, hook form should meet the design requirements. Stirrup adjustment, is the hook to increase the length and bending adjustment

Value or the difference between the two and, according to the amount of stirrup outsourcing size or inside the package size.

(4) reinforced blanking length should be according to the component size, concrete cover thickness, rebar bend modifier and hook to increase the length of the provisions as comprehensive exam


A. straight reinforced blanking length = member length - protective layer thickness increase length + hook,

B. turn up steel blanking length = straight length - bend modifier + + inclined curved length increase length of hook,

C. blanking length = stirrup stirrup inner perimeter + modifier + hook to increase length of stirrup.

Q:What is the specific concept of thread steel through water and what is the difference?
Most of the thread steel is subjected to self - tempering after water cooling, and the tempered bainite is obtained. The advantage is that the strength will be better; the disadvantage is that after rolling through water, the surface oxide film of steel is destroyed, rust is sure
Q:16 meters of thread steel, how many meters?
Thread steel factory specifications, part thickness is generally 9m or 12m root
Q:How many roots per ton of 18 thread steel?
18 of the rebar is one meter with a weight of 2kg
Q:Are steel bars used more in high-rise buildings or steel?
Look at the architectural design requirements and seismic grade, light steel reinforcement is mainly stirrups, columns, beams, shear walls generally use thread steel, plate bars and distribution bars are generally cold and twisted steel bars
Q:What is the relationship between the price and the hot coil steel prices?
The rebar prices are more special, in addition to energy-saving emission reduction, I personally think that the relationship between market supply and demand. In previous years, coil prices relatively high prices and price, usually in the coil as a goal. I think the price is not reasonable, but I don't understand, because I'm not an expert. Of course, the experts don't understand.
Q:Which is more expensive, rebar or round steel? Which is your business opportunity, such as thread steel and round bar?
Prices have been rising, customers have expressed that the purchase price increases, we will increase the cost of procurement, coupled with the pressure of funds, so we can not easily buy at the last minute.
Q:How much is the difference between the three grade thread steel and the two grade thread steel?
This is no fixed bar, probably in the difference between 50-150, the normal situation, but more or look at the supply and demand situation, there are two more expensive than three, the specific circumstances of specific analysis.
Q:Why is the price of screw steel affected by iron ore and coal?
The required material is simple, "billet, iron ore with a small amount of chemical elements", and then through the hot rolling method of refining, during which a large amount of coal is needed, so the price of rebar will be affected by iron ore and coal
Q:All knowledge about thread steel!
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. 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:What grade of reinforcement is used for cast-in-place floorslab?
Compared with the floor slab, the cast-in-place concrete can strengthen the integrity and the seismic resistance of the building, and has greater bearing capacity. At the same time, in insulation, sound insulation, waterproof and other aspects also have certain advantages.
