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.
- Q:How to recognize high quality thread steel
- Inferior steel due to poor production conditions, bulk, no metal signs, no quality guarantee. For safety reasons, we should not buy the inferior steel bars, or go to the direct agents of some famous brand manufacturers, so that the quality is guaranteed. Shandong hundred fertile Steel Pipe Co., Ltd. here recommends that users in the purchase of thread steel, must go to the formal steel business units to purchase, request steel quality certificate, and acceptance.
- Q:8 mm thread steel, how much is a bundle?
- 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.
- 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:Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
- If the reinforcement ratio of the situation, the use of 8 mm double reinforced than a layer of 10 mm steel is better, while using the double reinforced cast-in-place floor to prevent from the temperature shrinkage stress is good Oh, can actually try to use reinforced reinforcement ratio is moderate Oh, the only way to ensure the floor the panel does not appear the phenomenon of cracking, especially the roof panel, reinforcement ratio is very important.
- Q:What is the maximum tensile force of 25 thread steel?
- The specific parameters of common thread steel are:HRB335: yield strength: 335Mpa, tensile strength 445Mpa, elongation: 17%HRB400: yield strength: 400Mpa, tensile strength 540Mpa, elongation: 16%HRB500: yield strength: 500Mpa, tensile strength 630Mpa, elongation: 15%Ji'nan permanent thread steel tensile strength testing machine, Ji'nan permanent thread steel tensile test machine,
- 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:Can the bars of steel bars be replaced by round steel bars?
- Important stress parts should not be adopted. Reinforced surface made of thread, herringbone bond force is increased to crescent, steel and concrete, reinforced some parts if it is ends with a ribbed design can not bend, it is possible to design directly paste up, it is best to ask the design unit.
- Q:Are rebar bars = rebar?
- Rebar is only one of the reinforcing bars, and the reinforcing bars used in the construction site are distinguished from the appearance. They are mainly round steel (round steel bars) and plain steel (the appearance has lines, and the steel bars are divided into two kinds: thread and crescent).
- Q:Why does the steel thread have longitudinal ribs?
- The main function of the longitudinal ribs is the force to improve the performance of the transverse ribs, the stress of support surface transverse rib in the longitudinal direction, reducing flange stress concentration, so as to improve the mechanical strength of the reinforced rib, deformation of bond between concrete and steel reinforced concrete, the collaborative work and better.
- Q:What are the specifications of thread steel?
- China's standard recommended nominal diameter of 6, 8, 10, 12, 16, 20, 25, 32, 40, 50mm thread steel series.The supply length is divided into two kinds: foot length and foot length.China's export screw length selection range is 6 ~ 12m,The selection length of Japanese thread steel is 3.5 ~ 10m;Domestic sales of domestic thread steel, if the contract does not specify requirements, usually fixed length of 9m, 12m two length.
