The profile(hollow-square section) is one of the most important elements that can be used in various industries, which have different types and are produced in square, rectangular, circular, etc. shapes. These sections, which are included in the profile subcategory, are produced from different materials such as aluminum and steel, so they have various applications due to the type of production and the used items. The most common ones are metal structures, bridges, tall buildings, cars, airplanes and industrial equipment.

 

Profiles can be divided into two main categories; The first category is construction profiles and the second category is industrial profiles. Construction profiles are mostly used in the construction of doors, windows and fences, and industrial profiles are mostly used in the automotive industry.

Kian Kashan production profiles with ST37 steel alloy, which is widely used in various industries, are supplied with the best quality in various sizes and dimensions and the lowest possible weight with the possibility of 24-hour loading from the factory.

Due to the presence of some elements of manganese and silicon, ST37 alloy has machinability, which allows the use of heat treatment and machining in the production of parts required by industries. Manganese in steel combines with sulfur and prevents the formation of FeS, which is a brittle and undesirable structure. Also, by reducing the pearlite phase and forming a solid solution with ferrite, it increases the yield strength of steel.
