FAQ:

Q1: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will arrange production. The normal sizes with the normal grade can be produced within one month. The specific shipping date is dependent upon international and government factors, the delivery to international main port about 45-60days.

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: what is the difference between actual weight and theoretical weight?

A3: All the section steel has two weights: actual weight and theoretical weight. Actual weight is the weighing out when the product delivered from the mill. Theoretical weight is calculated by pieces.  The invoice can be based on each of them as your request.

Q:What is the content ratio of the screw steel and manganese steel?
Steel: content index mainly includes: C, Mn, P, S, Si, different grades, different content, its range is C (0.10 ~ 0.40%), Mn < 1.80%, P < 0.050%, S < 0.050%, Si (0.60 ~ 1%).
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:Does the grade three thread steel with "E" have the same information price as the ordinary three grade thread steel? Is there a big difference?
As far as I know, the price of information may not be divided into "E" and "E", but there are mandatory requirements on the standard. It is estimated that the price will not be much different.
Q:How is thread steel made?
The billets used in continuous small mills are generally continuous billets, the length of which is usually 130~160mm, the length is about 6~12 meters, and the billets are 1.5~3 tons in weight. The rolling line is mostly flat interchange arrangement to realize all round rolling without torsion. According to different billet specifications and finished sizes, there are 18, 20, 22 and 24 small mills, 18 of which are mainstream. The use of bar rolling reheating furnace, high pressure water descaling, in addition to the new technology of low-temperature rolling, endless rolling, rolling, rolling development to adapt and improve the precision of rolling billet, rolling mill is mainly to improve the accuracy and speed (up to 18m/s). Product specifications are generally phi 10-40mm, Phi Phi 6-32mm or 12-50mm. The steel grades produced are low, medium and high carbon steels and low-alloy steels, which are widely needed in the market. The maximum rolling speed is 18m/s. The production process is as follows:Reheating furnace, roughing mill, rolling mill, rolling mill, water cooling device, cooling bed, cold shear, automatic counting device, bundling machine, unloading bench is calculated from the Shanghai kuanli Steel Co. Ltd. to provide thread steel weight: diameter * * outer diameter theory 0.00617=kg/m theory and 6.50.260 steel manufacturers specifications Jiuzheng 8.00.395 Jiuzheng steel 100.617 steel 120.888 steel 141.21 nine nine nine nine nine steel 161.58 steel 182 steel 202.47 steel 222.98 steel 253.85 nine nine nine nine nine steel 284.83 steel 326.31 steel.
Q:What is the difference between plate and 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:Is the shear wall concealed column stirrup steel or round steel? What are you asking for?
Specify the construction drawing is HPB300 is hot rolled round bar, that is HRB335, HRB400 is the hot rolled ribbed bar. Don't call thread steel, this name has long been abandoned. Simple, light marked wall column reinforcement detail construction drawing on the diameter and spacing is not encrypted, what non encrypted area, like the dense spacing.
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:What are the main uses of threaded steel?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. Steel is usually used for reinforced concrete, its role is to increase the friction fringe, the rebar and concrete secant integrally formed together, tic phenomenon can not occur in the role of external force, improve the strength of concrete.
Q:Can the thread steel of the steel platform of the fixed unloading platform not work?
Steel bars on a fixed discharge platform must not be threaded. HPB grade reinforcement shall be used.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Fine grain hot-rolled steel grades in the hot rolled ribbed bar with English abbreviation "fine" English (Fine) first letter. Such as: HRBF335, HRBF400, HRBF500. There are higher requirements for the seismic structure, the applicable brand is: after the existing brand plus E (such as: HRB400E, HRBF400E).
