Angle Iron
Angle products are the products that enable the connections in the corners to be supported in a supported manner and that are effective in making the corners even stronger. Angle brackets, which have different types from each other, are iron-steel products that are generally produced in L-shape, and they are also called L iron due to their shape. There are iron angle iron types with different sizes. Depending on the types, it can be said that the angle products vary according to their price, as they can be used in most qualities.
Angle types used in the construction industry are often used in this and similar areas. However, it may be possible to talk about angular types such as equal sides and scales. These varieties are diversified in the direction of producing the dimensions according to which corners to be used for the usage areas. Today, widespread use of angle bracket types, which have different structures in terms of shape and provide harmony, are available in almost all construction sites.
Accordingly, completely iron and stainless steel angle iron models are used in different areas such as building skeletons. In which area it will be used, a reasonable material type is selected and a reasonable type of angle iron is produced. Iron angles that strengthen the system are also used in machinery and construction areas according to their types.
