Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
Q:What is the difference between steel and flat steel, round steel and steel?
In fact, for the processing of raw materials are the same, is used when the roller rolling pressure is not the same, there are many different types of tooth roller shaft, can produce different steel, the steel section is square, round cross section is round
Q:What is the reason that the diameter 130-45 round steel will break after welding?
You say this is a better situation, generally in a few days after welding on the crack, the most afraid of the key parts, to be a major accident. No. 45 steel can not be welded, such as welding, it is necessary to preheat before welding and after welding heat treatment.
Q:What's the difference between round steel and carbon bound steel?
Shape is different, round steel round appearance, no grain without ribs, carbon steel surface has engraved or ribbed, so that the round bar and concrete bonding force is small, carbon tie steel and concrete bonding force.
Q:What's the difference between Q345 round steel and No. 45 round steel material?
Q345 round steel is different from round steel No. 45:Q345 round steel containing Mn, but containing C below 45# round bar45# round steel containing C is higher than Q345 round steel, but without Mn
Q:What's the difference between bar and round bar?
If it is used for machining parts, it can be used in general. However, there are six bar material, and in general circumstances are not fixed feet, and round steel is generally sold according to the length of fixed length
Q:Is there a steel bar of 6 diameter on the market?
Reinforced concrete (Rebar) is used for reinforced concrete and prestressed reinforced concrete steel, its cross section is round, sometimes with rounded square.
Q:How to make the round welds on flat steel flat and qualified?
On both sides of the steel and welded steel plate, each side of the weld length of 5 times the diameter of reinforcement, welding seam should be welded into a convex arc that is.
Q:What is the diameter deviation of 12 mm galvanized round bar?
It is widely used in hardware, building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:Use of stainless steel round bar?
Stainless steel round bar has a broad application prospect, and is widely used in hardware, kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. Equipment, chemicals, dyes, paper making, oxalic acid, fertilizer, etc.; equipment for photography, food industry, coastal areas, ropes, CD poles, bolts, nuts, etc..
