Q:The steel structure material can do?
The steel can be used as structural materials to use, but not commonly used, are generally only used in the special requirements of the situation
Q:How to hollow square steel welding
Because the hollow steel thin wall, the use of electric welding should be used for small diameter with 2.5 electrodes, current should not be too large, can be around 100.
Q:The difference between cold and hot galvanized steel hollow where
Cold rolling process is: the strip through the mold, pipeline bending forming, and then through the automatic welding, the welding joints, and then polished, galvanized, also called seamed tube.
Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:The difference between galvanized square and galvanized steel
There is a difference in the quality of classification and can be processed into cold and hot dip galvanized pipe, galvanized pipe, galvanized pipe and galvanized belt can not be made, because of its wall thickness is thin, so the price will take the price dip galvanized pipe is much higher than galvanized pipe.
Q:As for steel structure steel, how appropriate
Column: 200*200*8 rectangular tube as column, beam (main beam) is 300*300*12, secondary beam is 150*150*8@1500 evenly distributed. Roof beam 150*150*8 herringbone roof truss.
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:Hot dip galvanized steel can be welded
Hot galvanized square tubes can be welded.Hot galvanized pipe, welding needs to be polished galvanized layer, thoroughly remove zinc coating and oil, dust and other debris, exposing the tube itself metal color, and then welding.Zinc melting point of 419.53 degrees Celsius, low melting point, Zinc Oxide Zinc Oxide formed layer of hot combustion in high temperature welding thousands of degrees Celsius in the combustion of white smoke barrier zinc combustion, influence the flow of the weld pool of liquid metal, destruction of welding arc stiffness, the porosity, slag, weld crack.
Q:What is the use of square steel keel or welding steel canopy
Sunshine board: advantages and characteristics of canopy cover top plate endurance detailed materials: flame retardant of spontaneous combustion temperature of 630 DEG C PC endurance board (wood 220 degrees C), by the national quality supervision and testing of fire building materials testing center, PC board of GB combustion (8624-1997 flame retardant grade B1), which belongs to the flame retardant engineering materials. Chemical corrosion resistant PC resistance board has good chemical resistance and corrosion resistance. It can resist all kinds of organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature. Heat resistant and cold resistant PC endurance board has good resistance to temperature difference. It can adapt to all kinds of severe weather changes from cold to high temperature. It can keep all kinds of physical performance indexes stable between -40 and 120 degrees centigrade. The photochemical PC resistance plate has the highest transmittance in visible and near infrared spectrum. Depending on the color, the transmittance is up to 12%-88%.
Q:How the steel columns and I-beam steel structure connection?
The square column is usually connected with a connecting plate, and the upper beam is arranged on the connecting plate and is fixed by an electric welding or a bolt.
