Product Description:

steel rebar is metal bars often used in construction for pouring concrete or supporting walls and columns. The 

rebar can be smooth, though they are frequently manufactured with deformations that create greater texture to 

which concrete can adhere, creating a stronger bond that helps prevent cracking of concrete. These deformations 

do not create weaknesses in the rebar, and when rebar is measured to determine its diameter, it is typically measured 

at the narrowest point. Strength grades indicate the amount of pressure the steel rebar can withstand, and grade and 

diameter are typically presented in both imperial and metric units

Q:The difference between rebar and crescent
Rebar -- steel used in concrete structures with a generally rounded cross section and ribbed surface.Longitudinal ribs -- uniform continuous ribs parallel to the axis of the steel bar -- other ribs not parallel to the axis of the reinforcement.The longitudinal section of crescent ribbed bars -- transverse rib reinforced crescent, and does not intersect with longitudinal ribs.
Q:What is the carbon content of thread steel?
Steel is very commonly used in the construction industry, so the wire in the production is there are some matters needing attention, such as the carbon content in steel, this is a very important decision index of thread steel hardness, so the carbon content in the steel is very important.
Q:What is the sign of steel rebar
Standards are the uniform rules for repeating things and concepts. It is based on the comprehensive achievements of science, technology and practical experience, and is approved by the competent authority and issued in a specific form by consensus by the parties concerned, as a criterion and basis for common compliance.
Q:What does it mean to have 22 4GJ on the threaded steel?
The brand of steel is expressed in terms of Arabia numerals or Arabia numerals plus English letters. HRB335, HRB400 and HRB500 are represented by 3, 4 and 5, respectively. HRBF335, HRBF400 and HRBF500 are represented by C3, C4 and C5 respectively. The name of the factory is expressed in Chinese phonetic prefix. Nominal diameter mm Arabia digital representation.
Q:What is the specific concept of thread steel through water and what is the difference?
Most of the thread steel is subjected to self - tempering after water cooling, and the tempered bainite is obtained. The advantage is that the strength will be better; the disadvantage is that after rolling through water, the surface oxide film of steel is destroyed, rust is sure
Q:How much is the weight of 6mm thread steel KG?
Rebar also depends on how many grades of steel can be used to determine the carrying capacity (tensile strength, design value). Grade two steel is 300 cow / square millimeter, grade three steel is 360 cow / square millimeter, grade four steel is 435 cow / square millimeter. Converted to 6mm steel, grade two steel is 847kg, grade three steel is 1017kg, grade four steel is 1229kg
Q:Why can't grounding steel be used?
When the thread steel is grounded, the contact with the soil is not dense, and the grounding resistance value is increased
Q:Cold drawn steel wire is a round bar or thread steel in Construction Engineering
Cold drawn steel wire should be the same as round steel and thread steel! Their forming process and the meaning of the place used are different, and the quota is also different, cold drawn steel wire is cold drawn steel wire, strictly speaking, there is no mix together.
Q:Why do stirrups have thread stirrups and round bars? When are they used?
Your question is actually related to steel and concrete work of a force of synergy in the reinforced concrete structure, steel usually is in tension, in order to ensure the reinforcement force can be well transferred to concrete, so as not to slip, we put the steel processing into whorl ribbed or other rib the shape, its purpose is to increase the adhesion between steel and concrete. Round steel is usually used in lower grade, smaller diameter reinforced steel, mainly because of its low strength, without adding ribs, round bar and concrete bonding between the relay can ensure that its strength is very good play. Therefore, steel bars are mainly used in places where the force is not large and the calculation of the reinforcement is very small.
Q:Why does the steel thread have longitudinal ribs?
Thread steel is inaccurate, commonly known as standard "deformed steel bars"". Hot rolled ribbed steel production in China, the surface usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution, when the longitudinal section transverse rib crescent, and does not intersect with the longitudinal ribs, called crescent rib reinforced; when the longitudinal section is equal to the height, and with the intersection of longitudinal ribs, said for high ribbed bar. The second and third grade ribbed bars commonly used in engineering usually adopt the crescent rib surface shape.Similar to the screw thread, our country did not produce, it is said that there is such a shape abroad.If it is necessary to say that it is possible to strengthen the tensile and shear strength, because after all, the longitudinal rib expands a little of the cross section of the steel bar. But this is not the purpose of rolling longitudinal rib, the purpose of longitudinal rib is to improve the mechanical performance of the transverse rib.
