Product Description:

bars of steel commonly used in construction, especially for reinforcing concrete structures such as driveways, 

foundations, walls, and columns. These bars come in different sizes and strength grades, and can be smooth 

or may include deformations that provide greater adhesion for concrete poured over the bars. When used in poured 

concrete, the bars are typically placed in a grid pattern, the concrete poured over them, and then readjusted to 

maintain the proper shape while the concrete sets. Steel rebar can be purchased from a number of manufacturers 

and is often found at construction retailers or large hardware stores

Q:32 of the rebar is one meter multiple
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 are the listed companies that produce wire rod and thread steel?
It is commonly known as steel hot rolled ribbed bar. 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 thread steel is a kind of small section steel, mainly used for the skeleton of reinforced concrete building member, the raw material for producing thread steel, and the carbon billet is a carbon structural steel or low-alloy structural steel which is treated by calm melting.
Q:What grade of reinforcement is used for cast-in-place floorslab?
Cast-in-place floors are usually made of grade two steel.Cast-in-place is relative to the precast slab, casting is to place a good template on the site, the installation of steel reinforcement on the template, and then pouring concrete on the template, and then remove the template.
Q:What are the different uses of wire rod and thread steel?
The wire is widely used, in addition to the direct reinforcement for building, and also can be processed into various kinds of special wire, such as spring steel wire and wire, galvanized wire, communication wire, steel cord, steel strand, etc.; it can also be processed into other metal products, such as rivets, screws, nails, etc.. According to data statistics, the general national wire output accounted for 5-15% of total steel output. China is now in the period of economic development, and a large number of wire rods are still needed for urban construction and settlement of residents' living conditions. In addition, the domestic demand for metal products increased, and the export volume of international trade continued to expand. China's wire output accounted for about 15% of the total output of steel.
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: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: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:How to calculate the theoretical elongation of finishing thread steel?
The theoretical elongation of fine thread steel is calculated by L=P.L/ (E.A), P is force, L steel bar is longer, E is elastic, and A is area.
Q:Now, the two project is to use rebar or rebar?
Suggest a slightly larger span of the floor, do not use round steel bar, or the use of thread steel bar, and then with anti crack steel.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Dowel arm for transverse construction joint. The transverse construction dowel bar is applied with a light circle and half coated with asphalt, allowing sliding. In practical application, the construction units are convenient for drawing, often use thread steel, and do not apply asphalt. The concrete pouring time on both sides of the construction joint is different, the contraction during the condensation process is not synchronous, and the dowel bar can not be stretched and formed a weak link. Cracks occur at this weak point when concrete slabs contract under loads or natural factors.
