 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 HR Deformed Steel Rebars of Good Quality:

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 terms: TT payment in advance or Irrevocable LC at sight.

Trade terms :FOB, CFR, CIF

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

FAQ:

Q1: What makes stainless steel stainless?

A1: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q2: Can stainless steel rust?

A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

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:What's the difference between earthquake resistant thread steel and common thread steel?
The seismic thread steel is much higher than the ordinary thread steel in the performance indexes, and the resistance to stress, bending force and so on are all higher than the ordinary thread steel.
Q:What is the difference between plate and steel?
Disk advantages: thread steel is only 9-12, can be screwed on demand random intercept.
Q:Thread steel 20*9 one is 2.001T. How many pieces of this one?
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.
Q:How much is the difference between the three grade thread steel and the two grade thread steel?
This depends on the size of the local quantity, and some are relatively hot specifications, prices may be a lot worse, may also be more expensive than the three class 2, but generally about 200 difference bar
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: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:Why do stirrups have thread stirrups and round bars? When are they used?
Oh, the main reason is the force, not only for steel rebar, general structure of round diameter is less than or equal to 10, 12 and above with rebar (hot-rolled ribbed bar)
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: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.
