Usage & Applications of Structure Steel Angle Bar

According to the needs of different structures, Angle can compose to different force support component, and also can be the connections between components. It is widely used in various building structures and engineering structures such as roof beams, bridges, transmission towers, hoisting machinery and transport machinery, ships, industrial furnaces, reaction tower, container frame and warehouse etc.

Q:What's the chemical reaction between stainless steel and galvanized angle iron?
The essential condition for stainless steel to be corrosion resistant is that the mass fraction of chromium must be greater than 10~12%. When the temperature increases, the diffusion velocity of carbon in the grain of stainless steel is higher than that of chromium. Because the solubility of carbon in austenite at room temperature is very small, about 0.02% ~ 0.03%, and the carbon content in austenite stainless steel are generally more than this value, the excess carbon will continue to austenite grain boundary diffusion, and chromium compounds, compounds of chromium carbide in the crystals, such as 23C6 (CrFe) etc.. The data show that chromium diffusion along the grain boundary activation capacity of 162 ~ 252KJ/mol, and Cr intracrystal diffusion activation energy is about 540KJ/mol, namely: chromium by intracrystal diffusion faster than chromium diffusion along the grain boundary velocity is small, the chromium was too late to grain boundary diffusion, so the main chromium chromium carbide formed in intergranular required not from the austenite grain interiors, but from the vicinity of the grain boundaries, the chromium content makes near the grain boundary is reduced, when the mass fraction of the grain boundary chromium low to less than 12%, the formation of the so-called "chromium depleted zone", in corrosion, will lose the chromium depleted zone corrosion resistance, and intergranular corrosion.
Q:What is the keel of the aluminum single board suspended or the welded frame of angle steel?
Light steel keel, is a kind of new building materials, with the rapid development of China's modernization construction, light steel keel is widely used in hotels, airport lounges, car transport station, station, amusement parks, shopping malls, factories, office buildings, building renovation, interior decoration, ceiling set of old buildings and other places. Light steel (paint) keel ceiling has light weight, high strength, adapt to waterproof, shock, dust, sound insulation, sound absorption, constant temperature and other effects, but also has the advantages of short construction period, simple construction and so on.
Q:What's the size of No. 5 angle iron?
The size of No. 5 angle steel is: steel with length, width and height of 50*50*xmm, wherein X can be 3mm, 4mm, 5mm.
Q:What does 50*50*5 angle mean?
50*50*5 angle means: the outer section of angle steel is 50mmx50mm, and the angle steel is 5mm.
Q:What does "angle length" and "limb width" mean?
Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:What is 4# angle iron? What are the classifications of angle iron? What are the specifications? Thank you
4# angle steel refers to both sides are 4 cm wide, the thickness of 4 mm angle iron.Angle steel has national standard, that is, the width of both sides is equal, the thickness is width 1/10, the length is usually 6 meters.
Q:What is the difference between galvanized steel bar and ordinary angle iron?
Low handling costs: the cost of hot dip galvanizing is lower than that of other paint coatings;
Q:What is the meaning of the number of angle steel
The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. The model can also be used, also the title number, number is the number of centimeters wide, such as the No. 3 angle angle 3#.
Q:What is the angle iron back machine?
With the development of the power industry, the manufacturing level of the power tower is becoming more and more demanding, and the planer processing method can not meet the requirements of production. The company's own design and manufacture of "CB2512" shovel back machine, the use of high-speed milling principle, used for angle steel shovel back process, the tower is the production of angle steel shovel back the first choice of equipment
Q:How much is a galvanized angle L50*50*5*2500
The ordinary angle iron is 40-45 yuan one
