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 are the listed companies that produce wire rod and thread steel?
The wire in iron and steel usually refers to a coil of wire material with a diameter of 5.5-14. Most of the use of wire coil machine rolled coil supply, it is also known as wire rod or coil. Wire rod is one of the varieties of steel with great dosage. After rolling, it can be directly used for reinforcement and welding structure of reinforced soil, and can also be used again and again. For example, by drawing into a variety of specifications of steel wire, steel wire rope, and then twisted into woven steel wire and winding and heat treatment to the spring; hot and cold forged into cold forging and rolling into rivets and bolts, screws and so on; by cutting into the heat treatment made of mechanical parts or tools; a common wire made of quality carbon steel and carbon steel.
Q:How heavy can a 25 mm thread steel bear?
25 thread steel one meter 3.86kg.Method of calculation: 0.00617 times the square of the diameter of the steel bar. The weight of each diameter of the steel bar (kg) can be calculated.
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:What specifications should be used for the three - step steel electroslag pressure welding electrode?
Three - step steel electroslag pressure welding electrode with 3mm diameter wire can be.
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:What's the difference between rebar and thread steel?
A ribbed steel bar with 2 longitudinal ribs and uniformly distributed ribs along the length. This is thread steel. It belongs to the category of reinforcement.
Q:Is the shear wall concealed column stirrup steel or round steel? What are you asking for?
Round bar is the finished steel hot rolling and cooling, by ordinary low carbon steel and alloy steel under the condition of high temperature pressing, mainly used for reinforcement of reinforced concrete and prestressed concrete structure, is one of the varieties of steel used in civil engineering in the largest amount.
Q:What is the diameter of the cross section of the threaded steel?
Upstairs method is also OK: use a rope around the thread steel for a week, and then take out the length of the string, that is, thread steel perimeter L, and then according to the perimeter formula, you can find the diameter of D=L/ Pi Pi =3.1415926.The most accurate way is to use a vernier caliper or a micrometer.
Q:What's the difference between finish rolling thread steel and ordinary thread steel?
The rebar used in prestressed concrete is a kind of bar with big diameter, high strength and high dimension precision, which is rolled with an external thread on the whole reinforcing bar. The steel bar is screwed at any cross section with a connector with an internal thread to connect or screw on the threaded nut for anchoring.
Q:Thread steel is embroidered after rain. Can it be used as reinforcing steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. 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 two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
