Q1: How do we guarantee the quality of our products?

A1: 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.

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 specific concept of thread steel through water and what is the difference?
Water cooling technology is used in the production of rebar, and the temperature of controlled cooling termination is higher than the recrystallization temperature of the material. If the temperature is obviously lower than the recrystallization temperature, the surface of the reinforcing steel is easy to form a thin layer of quenching and tempering structure. Quenching and tempering organization once formed, will undermine the strong cuby rebar and welding performance.
Q:How to calculate the theoretical elongation of finishing thread steel?
The theoretical elongation of fine thread steel is calculated by L=P.L/ (E.A), P is force, L steel bar is longer, E is elastic, and A is area.
Q:What is the difference between drawing steel and round steel on drawing?
When drawing steel, it should be used to correct the name: ribbed steel bar, whose name is abbreviated as "HRB" in English. At the same time, according to the characteristic value of yield strength, it can be divided into three grades: HRB335, HRB400 and HRB500, and should be marked when marked.Bar diameter and material should be marked on the drawing, such as material of 35 / Cr12.
Q:What are the main use of threaded steel?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members.
Q:Why do stirrups have thread stirrups and round bars? When are they used?
Hello, you say the problem is not what time, but the design requirements in that place, accept the stirrup size number with different encryption and so on, have a certain standard, the general drawings above have detailed instructions
Q:What is the carbon content of thread steel?
It is understood that carbon is the main element determining the performance of steel, because changes in carbon content directly lead to changes in crystal structure. With the increase of carbon content, the strength and hardness of the threaded steel increase, while the plasticity and toughness decrease. When the carbon content is more than 1%, the strength of the rebar decreases. The increase of carbon content also reduces the weldability and corrosion resistance of steel, and increases the cold brittleness and aging tendency of steel.
Q:What specifications should be used for the three - step steel electroslag pressure welding electrode?
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:Is thread steel rod or wire?
Steel is known as hot rolled ribbed bar.
Q:How to distinguish the quality of thread steel?
Inferior steel has no metallic luster and is pale red or similar to pig iron. The reason is two point two. Its billet is adobe. 2, the quality of stainless steel rolling temperature is not standard, their steel temperature is through visual inspection, this can not be rolled according to the provisions of the austenitic region, the performance of steel can not meet the standard.
Q:Like a steel rebar and wire spiral, is the same? What's the difference?
Generally, most of the diameter of thread steel in 10-34mm, while the general disk diameter less than 10mm, but also because of too small so often set up the price must be placed, what will be a little expensive disk. A house built of steel plate with the words to be used for different purposes. The price of concrete is not clear.
