Q:Will the theoretical weight of thread steel and round steel be the same?
The difference between such rebar and round bars with longitudinal ribs and transverse rib surface, usually with two longitudinal ribs and transverse ribs along the length direction of the uniform distribution.
Q:Are lightning checks required for galvanized steel, flat steel and round steel?
The corrosion resistance of cold galvanizing is not as good as that of hot-dip galvanizing. It is used as lightning protection and grounding material. It is corroded quickly, and the grounding resistance is raised rapidly. It exceeds the required resistance.
Q:20# difference between round bar and A3 round bar, can they be used separately?
20# rounds are plain carbon steel, as well as 10#, 20#, 45#, etc.A3 round bar is Q235, grade is ABCDE, etc., commonly used is Q235BIn use performance, 20# hardness is strong, but the elasticity is bad, welding performance is poorA3 hardness is less, but good elasticity, good welding performanceAs for specific can not be replaced, mainly depends on the use of places.
Q:Why do I use the M25 round bar for the embedded bolt M24?
The problem is that the reinforcement of this 36 is not ordinary steel. This steel bar is called general round bar, and its diameter is 36.2MM. Its concentricity is very high, it is a kind of reinforcing steel that is specially designed for bolt
Q:What's the difference between round steel and other steel bars?
The composition is different, round steel (grade a steel) belongs to ordinary low carbon steel, other steel bars are alloy steel
Q:Is round steel bar round steel?
Yes.From the shape of points for the light round steel, crescent steel, rebar.From the strength of reinforcement is divided into one level (235), two (335), three (435), four (435)Cold drawn from the production process (first tensioning and long pull method), cold and so on
Q:How to determine the welding seam height of steel plate and steel bar?
If the end of the vertical plane and the steel plate welding, welding angle as the bar diameter and the general welding height is 0.7 times the diameter of the arc can be reinforced; if the length direction of the surface of steel plate and steel welding, 2 side fillet weld cracks in the welded steel plate and steel between the full and round steel weldment the maximum diameter of arc phase can be flat.
Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Worm and worm type steel bar benderStructure: worm and worm type steel bending machine, mainly each family, motor, transmission system, work mechanism (work disk, insert seat, gripper, shaft, etc.) and control system. A walking wheel is arranged under the frame for easy movement.Working principle: the power of the motor is rotated by the V belt pulley, the two straight gear and the worm gear rod, and then drives the working disk to rotate. The working disk usually has 9 shafts, the center hole is used to insert the central shaft, and the 8 hole seats around each have 6 holes, which are used to insert the retaining shaft. In order to move the reinforcing steel bar, two times of each work table is also provided with a feeding roller. When working, according to the bending shape of the steel bar, the square of the reinforcing steel bar is arranged between the central axis of the work disc and the corresponding forming shaft, and the inner side of the iron block is blocked. When the working disc is rotated, one end of the reinforcing bar is prevented from rotating by the iron blocking shaft, the central shaft position is fixed, and the forming shaft is rotated in an arc direction around the central shaft, and the reinforcing bar is bent.As a result of the specification, the bending diameter of the steel bar shall be no less than 2.5 times of the diameter of the steel bar when it is taken as a 180 degree bending hook. Therefore, the center shaft is also made into 16~100mm in 9 different specifications to meet the requirements of bending different diameter steel bars.
Q:Do you need paint for roof lightning proof steel bars?
The roof lightning protection round steel is the use of metal electrical conductivity and the principle of point discharge, the accumulation of the earth's electricity more rapidly spread to the air, play a role in lightning.
Q:What kind of steel pipe is round steel?
A round bar is not a steel tube. In brief, its section is round, but it is solid, and the cross section of the pipe is hollow.
