Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
The general drawing bar is 6 meters, some ribbed bars 9 meters and 12 meters two tons of steel; a number of roots can not say, can be 1 or 100 roots, the length of thickness do not know how to tell you how many tons of reinforced root ah.
Q:How to determine the welding seam height of steel plate and steel bar?
If the arc surface in the length direction of the steel bar is lapped welded with the steel plate surface, the gap between the steel plate and the round bar is welded by the 2 side welding angle, so that the welded meat is equal to the largest diameter of the round steel arc surface.
Q:Will the theoretical weight of thread steel and round steel be the same?
The theoretical weight of threaded steel and round steel is the same. The middle part of the steel bar size ratio is small, the design time actually unit weight are the same, just screw steel crescent and transverse ribs prominent, resulting in heavy steel should be better than the illusion of formula is 0.00617 multiplied by the square of the diameter / m.
Q:How can I connect channel steel and round steel?
First, the channel steel, channel cut, need to connect the length of the arc shaped gap, and then again and round steel arc surface welding, welding before the two kinds of materials to rust, and full welding.
Q:Is round steel round 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:Is there any technique for welding round steel?
Welding skills:2.1, to determine the best welding position, the group of good welding flat, easy to rotate welding, the weld pool is always in flat position, note the rod angle at 70 degrees.2.2, the welding workpiece in continuous continuous rotation, to control the size of the weld pool at the end of each lap weld slag, cleaned, and then welding together, the thickness of each layer is about 2mm, until the full fill slope has so far.
Q:What is the diameter deviation of 12 mm galvanized round bar?
Hot galvanized 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: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 to distinguish a round bar from forging? Cold drawing? Hot rolling?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
