Q:Which is hard, round steel or screw steel?
The difference between steel and other steel: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other. 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:The difference between 304 stainless steel round bar and bright round bar
The difference between the stainless steel round bar and the bright round steel of the same material is that the bright circle is cold rolled (or cold drawn), and the black circle is hot rolledThe processing method is different
Q:The two project is to use rebar or rebar?
It is recommended to use thread steel as far as possible, because the bonding force and holding force of the thread steel is better than that of the round steel, and it is generally known that the tensile pulling force of the round steel is relatively poor.
Q:The problem of dowel bars on concrete pavements?
The dowel bar is arranged according to the transverse contraction joint and expansion joint set, meaning that a transverse contraction joint and expansion joint place dowels, are not plate must be set. In general, each 200m set a expansion joint, or other road intersection, and bridge connecting point must be set up.
Q:40CrMo what is the round steel material?
High strength, high hardenability, good toughness, little deformation during quenching and high creep strength and lasting strength at high temperature.
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
Generally, the length of steel bars is 6 meters, 9 meters, 12 meters, 6 meters, which is rarely seen on the construction site. A standard bundle is 2 tons.
Q:Why is a steel rope made of many wires rather than a round bar of steel?
The multi ply, in order to increase the cross-sectional area increases the tension will not suddenly broken, fine wire bend more easily, so the bending of wick core can be better, with better lubrication of steel wire rope. If it is a steel bar, it is not easy to bend, it is easy to break suddenly, and the practicability is poor.
Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
Don't need, but the welding seam area not less than round or flat between the relatively small cross section, the weld to coated with anticorrosive paint. Generally speaking, the grounding part does not use steel, galvanized L type flat iron good effect (copper strip and galvanized L type flat iron is not much, just life is long, but the cost is much higher), round only used as grid wiring.
Q:Difference between cold drawn round steel and round steel
The free torsion rigidity of hot rolled steel is higher than that of cold rolled steel, so the torsion resistance of hot rolled steel is better than that of cold rolled steel.
Q:Which is stronger, steel pipe or round steel? Which is good at bending?
Of resistance to shearing, of course, of high round steel, generally used with steel tubes (light weight and material saving) for transmitting torque
