Square Iron
Square filled irons are produced by subjecting the hot rolling technique. Although the existing corners of these products are equal to each other, they have high durability. At the same time, they can also be produced within the scope of cold drawing technique according to their sectoral usage purposes. These rolled products, which have a high level of weight-bearing power, stand out with their high corrosion resistance. The reason why it is frequently preferred in various sectors is due to its durable structure along with these features. For those who are wondering what square-filled iron is, we also comprehensively discuss what it does. Square solid iron, which is widely used in general assembly procedures along with production, can be produced from all kinds of materials. However, it contains various features.
Square filled irons have many superior qualities as well as their durability. One of its most distinctive features is that it can simply take form. In this context, it offers quite simplicity in terms of welding, cutting, shaping and processing. While we operate sensitively with the focus of routine controls during the delivery phase, we provide a privileged experience with our expert team.
Usage areas
Square solid bars have a stainless structure within the scope of their tensile strength. Therefore, it is used in many different sectors. One of the most preferred areas with its maximum resistance power is undoubtedly the construction sector. Square filled bars are used in the supports of various structures. Therefore, construction structures gain a form that is highly resistant to outdoor conditions and possible natural disasters.
One of the sectors in which square-filled iron is used most widely is scaffolding construction. It plays an important role in the construction of solid structures with its functionality and superior corrosion resistance. These products, which have a very high weight-bearing capacity, show a superior performance when used in concrete foundations. It is also preferred in the construction of windows and doors. The reason why it is used especially in areas such as railings is due to its superior strength.
It is possible to use square solid irons, produced in stainless form, in all construction areas, including crane construction, together with their durability. These parts, which are described as rolled products, are preferred in the production of most ornaments. You can access square solid irons needed both in assembly and production stages within the scope of our company’s high quality. Developed in reasonable weights and dimensions for your project, these products appeal to different areas of use with their versatile functionality and provide maximum functionality.
