I would like to ask you, angle iron, what does it usually use ah?
Electrical installation is often used with 40 x 4 angle angle and angle of 50 * 5 / two, 40 * 4 steel commonly used in porcelain wiring and lighting piping, use 50 x 5 angle angle is more extensive, such as cable bracket, power piping, busbar support installation, can replace the cable bridge frame the arm. Usually the iron angle, anti rust paint and gray paint brush.
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
Angle steel manufacturing process is relatively simple, the general large-scale Steel Corp really do not produce this thing, the production process can be divided into two types of hot rolling and cold bending, hot rolling for large size angle steel, cold bending is generally relatively small. Is the standard process for steel billet (such as billet) after steel mill multi special rolling gradually rolled into "shape, material guarantee, there is a transition arc in the medial angle, reliable mechanical performance; while small workshop production is a sheet or strip casting (curved) into the medial angle of no transition arc, but also because it is in the corner of the internal stress of bending into large, mechanical performance is poor, the most important point is that material is not guaranteed, even may be the land of steel, so the angle to buy back is generally not bent, nor welding, up to take long short borehole.
Mainly used for making steel frame structure, such as high-voltage transmission tower, steel structure bridge on both sides of the frame, the construction site of the tower crane arm, workshop columns and columns and beams, small holiday places such as roadside stands, the window in the other pot under the air conditioning solar rack etc..
