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 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

FAQ:

Q1: Can stainless steel rust?

A1: 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.

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

bdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q:16 meters of thread steel, how many meters?
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:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Longitudinal tie rod. Longitudinal seam usually has longitudinal contraction joint and longitudinal construction joint two kinds, two kinds of longitudinal joints should be provided with tie rod. The bar shall be designed with the length of the threaded steel to ensure the bond between it and the concrete, and the diameter and spacing of the tie rod shall also be guaranteed. Thus, the tie rod can not provide enough tensile force, and when the concrete faceplate is contracted, the longitudinal joint is pulled apart to form a crack.
Q:Is the theoretical weight of threaded steel and round steel the same?
The difference between such rebar and round bars with longitudinal ribs and transverse rib surface, usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution.
Q:How many patterns are there in threaded steel?
According to the shape of steel ribs, there are three kinds of patterns: herringbone spiral and crescent shaped patternSteel 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:What is the difference between the material of steel thread and its use?
Main uses: widely used in housing, bridges, roads and other civil engineering construction.Main origin: the manufacturer of thread steel is mainly distributed in North China and Northeast China
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:Excuse me, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer
Anything you say can be called steel bar, except steel wire. Round and round is a name, and wire coil, general line.
Q:25 screw steel, how many meters per meter?
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.
Q:Why does the steel thread have longitudinal ribs?
The effect of the longitudinal ribs is indirect, which improves the mechanical properties of the transverse ribs and indirectly enhances the bond with the concrete.
Q:What are the main uses of threaded steel?
The main use of rebar is to use beams and columns of important structures as well as bridges. The upper rib is stronger than the round steel when combined with concrete pouring!
