Usage and Applications of HRB400 Deformed Steel Bar:

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 HRB400 Deformed Steel Bar:

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.

Each bundle weight: 2-3MT, or as required

Payment term: TT or L/C

Delivery Detail: within 45 days after received advanced payment or LC.

Label: to be specified by customer, generally, each bundle has 1-2 labels

Trade terms: FOB, CFR, CIF

Q:What is the quality difference between round bar and screw steel?
Different shape. The outer surface of the round steel is smooth; the outer surface of the spiral steel has a spiral rib. 2. different production standards. In the current standard, round bar that HPB235 grade steel, and its production standards are "hot-rolled smooth steel reinforced concrete" (GB13013); rebar generally refers to HRB335 and HRB400 grade steel, its production standard is "the reinforcement of concrete hot rolled ribbed bar" (GB1499). 3. different strength. The design strength of round steel (HPB235) is 210MPa; the strength of thread steel is higher than that of round bar; the design strength of HRB335 is 300MPa; the design strength of HRB400 is 360MPa.
Q:Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
The plate near the gable should be equipped with double - layer reinforced wire mesh. Adding radial reinforcement at the corner of the wall. In the region where the temperature and shrinkage stress are greater, a double layer steel mesh should be installed.
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:The difference between rebar and crescent
From the shape of the rebar, the longitudinal rib and the cross rib intersect to form a thread; the crescent shaped steel bar looks from the shape, the longitudinal rib and the transverse rib do not intersect.
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:Is the finish steel 3 grade steel?
The finish rolling thread steel is not 3 grade steel, and the 3 grade finish rolling thread steel is common thread steel.
Q:How to judge the quality of thread steel?
Appearance check the necking fracture, peeling, oil pollution, damage, deformation, diameter error, third is the best for the test, according to the provisions of the current "reinforced concrete hot-rolled ribbed bar" GB1499 current national sample sent to the laboratory test, the sample collected for tests of mechanical properties, such as more than three are qualified, steel is good the!
Q:Sixteen mm steel, 12 meters long, a ton, how many roots?
The weight of that one 12m is 12*1.58=18.96kg. 1 tons =1000kg. That's 1 tons: 1000 divided by 18.96, about 52. Hope to help you.
Q:Are rebar bars = rebar?
Rebar is only one of the reinforcing bars, and the reinforcing bars used in the construction site are distinguished from the appearance. They are mainly round steel (round steel bars) and plain steel (the appearance has lines, and the steel bars are divided into two kinds: thread and crescent).
Q:Difference between round bar and threaded steel in use
Because the surface has a thread shape, it can increase the firm bond with the concrete. The longitudinal reinforcement and stirrups shall be used preferentially in the concrete members.
