Angle Steel Bars are a type of structural steel which are L shaped.Other forms include the T bean, Z shape, Channel, T shaped, Bar,Rod, Plate, and Asymmetrical I Beams.These bars can be made out of a number of different materialseach of which contain different properties and thus are used fordifferent purposes. Carbon steels are generally used for structuralshapes, pipes, plates and tubing. High strength low alloy steels areused for the same as carbon but also W shapes. Corrosionresistant high strength is only structural shapes and plateswhereas quenched and tempered alloy steels are used forstructural plates, plates and boilers and pressure valves.
The composition of the steel involved also changes theproperties of the material. Often coatings are applied to steel to attempt to increase the critical temperature which is thetemperature in which the steel is unable to bear its load. The thermal properties of steel vary depending on the composition of the alloy. The cauterizing temperature which is the temperature at which the steel becomes a crystal structure is used to compare. Pure Iron is 900 centigrade, eutectic is far lower and when more carbon is added, this temperature will increase again. When the carbon levels are above 2.1%, the name is no longer steel but cast iron.
There are number of ways in which steel can be bent including pressbrake forming, three point bending, folding, wiping, rotary bending,elastomer bending and jogging. There are three types of press brakeforming and these are air bending, bottoming and coining and in all of these a punch provides the force required for bending the steel.
There are a number of uses for angle steel bar and they are generally structural, the steel helps provide a force to hold items in place. Therefore it is imperative that the angle produced is so exact andvarious calculations are used to ensure that this is the case. There are many different companies available which are able to offer specialised cutting allowing the exact size and angle to be formed for different needs.
