FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How many tons of steel products could be loaded in containers?

A2: Usually the steel products are delivered by bulk vessel because of the large quantity and the freight. However, there are no bulk vessel enter some seaports so that we have to deliver the cargo by containers. The 6m steel product can be loaded in 20FT container, but the quantity is changed according to the size, usually from 18tons to 25tons.

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:How to calculate the theoretical elongation of finishing thread steel?
Rebar is a kind of special bar with discontinuous external thread. The steel bar can be connected or anchored at any section with a connector or anchor with internal thread.
Q:What is the difference between grade two and three grade steel?
But from the definition we can see more of the same point, all belong to the common low alloy hot rolled ribbed steel bars; belong to (usually said that the rebar); can be used for engineering in reinforced concrete structure.
Q:Thread steel generally used for more?
Mainly used for reinforcement of reinforced concrete and prestressed concrete structures. It is one of the most widely used kinds of steel in civil engineering.
Q:What is the difference between drawing steel and round steel on drawing?
Said method of thread steel: a circle and a vertical line and a horizontal line is a steel, is two steel, and then a circle and a vertical line and two line is the steel line below, but the level of a level, is grade three steel.
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: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:What is the difference between the II and III grades of threaded steel?
Compared with traditional II grade steel, the characteristics are as follows:1, high corrosion resistance, can be a large number of security reserves.2. In the chemical composition, because of the low carbon equivalent of the new third grade steel, the welding performance is good.3, high strength ratio, meet the seismic performance requirements. Particularly suitable for high-rise buildings and high seismic performance requirements of the project.4, cold bending performance is good, can be repeatedly bent, more in line with and meet the construction requirements of the construction.5, because of the high strength, can reduce the use of steel, effectively solve the problem of reinforcing steel bars too close, easy to concrete pouring. At the same time, it also reduces the cost of steel transportation and on-site processing.
Q:What is the relationship between steel structure and thread steel?
The main material of the steel structure workshop is I-beam and channel steel, which are welded or riveted.
Q:How to calculate the theory of steel thread?
Calculation method: diameter * diameter *.00617*12 meters * one package of roots = a bundle of weight.
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.
