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:Are steel bars used more in high-rise buildings or steel?
The shear wall structure is used in many round bars, such as vertical wall bars, horizontal bars, steel bars and stirrups. Note that only general structures are concerned.
Q:Are thread steels of coarse steel?
Thread steel does not belong to coarse steel, rough is shaped steel, fine is wire.
Q:What is the sign of steel rebar
Standards are the uniform rules for repeating things and concepts. It is based on the comprehensive achievements of science, technology and practical experience, and is approved by the competent authority and issued in a specific form by consensus by the parties concerned, as a criterion and basis for common compliance.
Q:How much is the minus difference per ton of thread steel?
H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
Q:Difference between round bar and threaded steel in use
Because steel for low alloy steel, its price is higher than that of low carbon steel, or construction units, design units, often on the general civil construction of the "practical" point of view, reduce the quality of the project, and the use of low carbon steel instead of rebar. For large engineering projects, often bribed "project inspector after" to replace "Choulianghuanzhu rib steel bar, reduce the construction cost.
Q:What's the difference between earthquake resistant thread steel and common thread steel?
Seismic steel can meet all the performance indexes of ordinary steel, but also can satisfy the tensile strength and yield strength of the actually measured ratio of not less than 1.25 characters; yield strength and yield strength characteristics measured standard value of the ratio is not greater than 1.30; Taiyuan dedicated steel maximum force elongation of not less than 9%, the three criteria.
Q:Why is the price of screw steel affected by iron ore and coal?
At the same time, rebar is the largest type of steel in our country and is the seller's market.
Q:What is the difference between rebar bolts and steel bars?
Rebar is only material, and thread steel bolt is the product after the thread steel is processed.
Q:Laiwu steel thread steel trademark color blue and red Qu Qu
In the purchase of rebar, first of all, from the surface quality, the surface of normal steel without cracks, scarring and folding. The surface shall have a bump, but shall not exceed the height of the cross rib, and shall also have a quality grade mark on the surface of the steel bar. Inferior thread steel due to rolling with adobe, its surface quality is poor, often with burrs, burrs, cracks, scarring, some distortions obvious, end of irregular, and even cracks. At the same time, some small mill due to heating temperature and rolling speed is not enough, the surface color is red, uneven color. Second, from the appearance of size, you can use vernier caliper to measure whether the actual size is consistent with the marked size (general thread steel rolled with specifications), if there is a difference in the standard deviation (such as? 16 the standard diameter of the thread steel is 15.4 + 0.4mm, while the quality of the false thread steel is mostly about 13mm. Third, regular steel at the factory, mostly large bundles of packaging, bundles of steel are linked with the physical corresponding metal signs, indicating the factory name, steel number, batch number, specifications and inspection code. But shoddy steel due to poor production conditions, no large hoisting equipment, mostly small (about ten strapping) package or in bulk, no metal signs, no guarantee of quality.
Q:Why is round bar more expensive than thread steel?
Threaded steel should be used in the construction field, there are generally two, three grade steel, grade HRB335, HRB400 also has four grades, HRB500 thread steel.
