Q:Is round steel bar round steel?
Yes.From the shape of points for the light round steel, crescent steel, rebar.From the strength of reinforcement is divided into one level (235), two (335), three (435), four (435)Cold drawn from the production process (first tensioning and long pull method), cold and so on
Q:The problem of dowel bars on concrete pavements?
The left and right half of the casting, the middle of the set is a longitudinal pull rod, tie rod settings and your panel thickness and plate width, length of the boardTo Portland cement concrete surface layer as an example: when the plate is 3M, the thickness of the surface layer is 200-250mm, the rod Phi 14 * 700mm * 900mm rebar length and spacing from the lateral transverse joint distance not less than 10mm (mean distance is a piece of plate length is 4 meters to the two plates the net is not small 100mm).
Q:How can a round steel weld on a flat steel plate be 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:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
Unwanted。 The round bar shall be welded directly on flat steel, requiring both sides of the round bar to be welded, and the length of lap welding shall be 6 times of the diameter of round steel.
Q:What kind of material is the first round steel?
[round bar] refers to the cross section of round solid steel. Round bar is divided into three parts: hot rolling, forging and cold drawing.
Q:What are square steel, rectangular tube, angle steel or light steel?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.I-beam, channel and angle steel are widely used in industrial buildings and metal structures, such as factories, bridges, ships, agricultural machinery, vehicle manufacturing, transmission towers, transport machinery, often in conjunction with the use of. Flat steel is used as a bridge, a housing, a fence, a transmission ship, a vehicle, etc. on a construction site. Round steel and square steel are used for all kinds of machine parts, agricultural machinery parts, tools and so on.Medium type steel: medium type steel, medium, groove, corner, round, flat steel use, similar to large steel.Small steel: small steel, middle, round, square, flat steel processing and use similar to large steel, small diameter round steel is often used for building steel
Q:Are steel and round steel the same thing?
Yuan steel and round steel are the same thing, they are round steel.
Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
The general situation is not possible, but sometimes as stirrup time, and has little effect on the structure, if 12 reinforced with missing a few, but not on the main force position is possible, sometimes supervision is not allowed.
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: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.
