Q:What is galvanized round bar?
Galvanized round bar generally refers to the wiring used for lightning protection in construction and installation. It is made of ordinary round steel (usually 8mm to 12mm diameter) and protected by electro galvanized protection layer. Galvanizing, differentiation, plating and electroplating, cold galvanizing and hot galvanizing etc..
Q:How to make the round welds on flat steel flat and qualified?
If it is full weld, for strong, don't groove. There must be no problem with the welding. If you hit the groove, it will deform. When welding, you should do spot welding and diagonal welding. I think you should be able to understand this, but I don't know what you are using for it,
Q:What are the differences between the products made of wrought round steel and hot rolled round steel and tested by mechanical testing after heat treatment?
The longitudinal and transverse properties of the free forging or hammer forgings are relatively small, the banded structure is not obvious, and the plastic inclusions are less deformedIt is not suitable to use rolled material for the workpiece with higher requirement of transverse or tangential performanceSampling position should be the same, usually in accordance with standards or technical requirements, such as vertical performance of a three pull, take at 2/3R
Q:What is the tensile strength of round steel bars of diameter 28?
The tensile strength of round steel bars of diameter 28 is 27079.36~33849.2 kg. It is explained as follows: the material of rebar is generally Q235-A carbon structural steel, its yield strength is 235 MPa, tensile strength is 441~550 MPa, and it is 44~55 kg / mm2. The cross-sectional area of 28 mm in diameter is about 615.44 mm2, and its tensile strength is about 27079.36~33849.2 kg.
Q:45# what are the main rounds for?
45# round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter
Q:Difference between round bar and other steel bars
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
The tensile capacity of the anchor bolt is the tensile capacity of the round bar itself. The size is equal to the sectional area multiplied by the allowable stress (Q235B:140MPa, 16Mn, or, Q345:170MPA), that is, the allowable tensile load capacity at design time.
Q:Will the three steel is steel? It is a steel bar?
Your question is inaccurateThread steels are grade two, grade three, grade four, and even grade fiveFirst grade steel generally refers to the wire rod, also known as wire rod, is a ribbed steel bar
Q:Difference between cold drawn round steel and round steel
Cold formed steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
Q:Could you tell me what is the difference between steel pipe and round steel?
Widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
