Q:Square steel and C steel which is better?
24 square meters, not ordinary sandwich panels, the proposed use of square tubes, want to secure a little, then use C steel, depending on how thick material and decided to require more detailed information, you can find me, I do color steel sandwich panels
Q:Round and square steel which is strong
The steel production and processing type of hot-rolled and cold drawn two. Hot rolled steel length of 5 ~ 250mm, 3 ~ 100mm length of cold drawn steel.According to the carbon content and the corresponding use, import and export of round steel can be divided into two categories: low carbon round bar and medium carbon. Low carbon raw materials mainly used for wire drawing, forging rivets, bolts and nuts and other metal products. Carbon steel and round steel commonly used to make mechanical parts.
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:How to ensure the steel paint off paint
The first thing to do (clean dust, oil removal, in addition to soluble salts), and then choose to kill or polish, then under suitable conditions (humidity is less than 85%, the substrate temperature is higher than the dew point of at least 3 degrees Celsius) and construction paint. Well done, the paint won't fall off.
Q:Why is a point of penetration of 2 square steel welding
With 2.5 of the electrode try, I solder 1 will do, hand gestures as soon as possible, it is not so easy to point out the hole, if the conditions can choose carbon dioxide protection welding, but the cost of welding should be high
Q:The difference between square and square.
Square refers to the use of a square billet material rolled out, or by round steel after cold drawing process, the material out of the square. Formula weight: side length of square theory * * 0.00785=kg/m.
Q:The anti-theft lock in the steel compression spring is what?
The use of stainless steel spring wire suspension spring wire is advanced, high strength, long fatigue life, the effect is good damping characteristics, spring steel wire, the number and distribution of inclusions, so the chemical, high surface quality, decarbonization, microstructure and mechanical performance requirements.
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:How to fix the steel Aluminum Alloy
With self tapping screws, that is, with drill screws, building materials market can buy. Electric screwdriver, you can put the wood board through self tapping screws into the steel. But attention should be paid to buy the self tapping screw length, short patch does not live too long into the square, too much is not good.
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.
