Q:Why is the round bar bent?
Round steel with hooks the aim is to increase the bond between concrete and prevent the component in the tension will be reinforced. Therefore, round bars should be 180 degrees of hook, should set up 90 degree hook ribbed bar.
Q:Use of stainless steel round bar?
Stainless steel round bar is a kind of long material, and it is also a kind of bar. The so-called stainless steel round bar refers to the cross section is even round long material, generally about four meters long.
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Flat steel adopts negative deviation rolling, but according to actual weight delivery, the utilization ratio of steel plate increased by -5 percentage points. Flat can according to user needs, set the thickness, width and length of production, for the user to reduce the cut and save processes, reducing labor, material consumption, but also reduce the loss of raw materials processing, time saving, material saving. Products have been specialized in steel structure manufacturing, machinery manufacturing, automotive industry, mining machinery, lifting machinery and other industrial materials.
Q:What's the difference between Q345 round steel and No. 45 round steel material?
Q345: it is a kind of manganese steel (16Mn), yielding strength of 345, good welding performance, commonly used in structural parts welding, low carbon steel, can not be used for quenching or quenching and tempering.No. 45 Steel: high quality carbon structural steel, medium carbon steel. Can be used for quenching or tempering.
Q:Which steel wire is the same diameter as round steel more resistant to breaking?
The same diameter wire rope and round steel, steel wire rope is more resistant to break.
Q:Is round bar steel?
Round steel is the term of steel structure, and the requirement of material is different from that of concrete structure.
Q:Do you need paint for roof lightning proof steel bars?
The roof of the round steel as long as the welded joints painted anti rust paint is good, should not be painted a large area. When the flash device is made of steel material, hot-dip galvanized steel shall be used and corrosion resistant by zinc plating.
Q:Weight algorithm of round steel
1, the appearance is different, round steel appearance of round, no grain without ribs, other steel surface appearance has carved or ribbed, this causes the round bar and concrete bonding force is small, and other steel and concrete bonding force.2 ingredients are different, round steel (grade a steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel. 3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller.
Q:What is the reason that the diameter 130-45 round steel will break after welding?
Steel No. 45 belongs to medium carbon steel. Because of its high carbon content, it has poor weldability, but its comprehensive property is good. If welding is needed, it needs to be preheated before welding and heat treated after welding to reduce its internal stress. The more commonly used weldability is No. 20 steel. In order to improve the performance of No. 20 steel, heat treatment is usually applied to its surface.
Q:Can the same grade steel instead of round bar be ok?
The above analysis, threaded steel than round steel performance is good, in general circumstances can be replaced.
