Q:Are square steel, rectangular tube and angle steel shaped or light steel?
Section steel is a kind of strip steel with definite section shape and size.In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape.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:It can be used as the steel electrical equipment grounding
In the electrical grounding body, generally use the steel pipe, angle steel, flat steel, round steel and other steel specially made grounding. The artificial grounding body and the ground wire form a grounding device, so that various earthing of the electrical equipment is connected with the ground through a grounding device. The artificial earthing body has two kinds of vertical embedment and horizontal embedment. The vertical buried pipe, angle steel, round steel grounding body, and have sufficient mechanical strength; ground level buried body with round steel, flat steel, common type, with several ring and radiation type. It is better to use galvanized steel when laying artificial earth in strongly corrosive soil. The steel used in the earth body shall be in accordance with the requirements of thermal stability and uniform pressure.
Q:The steel structure material can do?
First of all, will cause the waste of steel using square large section case, increase the weight of the structure, which is contrary to the steel structure of light weight advantages, small cross section from the processing, production process, the use of steel will be more, in addition to the special requirements, do not recommend the use of square steel.
Q:The difference between square and square.
Square tube is kind of square body, many kinds of material can form a square body, most square to steel for the majority, after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into square tube and then cut into the desired length. Usually 50 bags each. Square pipe in the spot with large specifications in most, in the range of 10*10*0.8-1.5 to 500*500*10-25, square tube by use is divided into structural square tube, decorative square pipe, building square pipe, mechanical square tube, etc..Square tube is a square tube of a name, that is, the length of the same steel pipe. The strip is rolled by process.
Q:How to combine the paint and galvanized steel
No, as long as you choose the special galvanized steel pipe paint, mcGZ type is ok!
Q:4 x6 1.5 square meters thick, how much money
The steel prices generally calculated in tons. To see you say the steel is hot dip galvanized or black material. Hot galvanized general 4500/ tons, black wood generally in 3800/ tons. That is 4.5 yuan /kg and 3.8 yuan /kg. Forget it. You say this kind of steel is 2.355kg per meter. You can tell by your own price.
Q:The moment 2mm thick galvanized square steel tube using what welding methods
If the mind zinc burning for the tube effect, can use silicon bronze gas welding, Odin 204Si, with special reference "Wiodin 204Si bronze wire in welding of galvanized plate"
Q:Twist steel (twisting steel) there is no standard?
Because the steel plate for standard parts, CAD drawing without draw, only need to mark the type and size of the bearing flat steel lattice steel plate and the direction of the steel grid plate, the specific use of what types of bar, can be specified by the user, if the platform is too large, can be discharged from the layout of steel grid plate manufacturers, general row layout is free.
Q:As for steel structure steel, how appropriate
The size of the material is strongly related to the load on your floor, and the roof material and column size are also related to your span and the local Blizzard loads. You can choose the size of the material according to the local conditions.
Q:The difference between cold and hot galvanized steel hollow where
Hot rolling process is: the ingot directly into square tube, and then galvanized, also known as seamless pipe.Usually than cold-rolled steel hot-rolled square steel prices high.
