Square IronWhy?
Square filled irons, hot rollingproduced using the technique. Although the existing corners of these products are equal to each other,highdurabilityhas the feature. At the same time, according to sectoral usage purposescold drawingcan also be produced using the technique. 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.square filled ironFor those who are wondering what it is, we also comprehensively discuss what it does. Widely used in manufacturing as well as general assembly proceduressquare filled ironcan be produced from all kinds of materials. However, it contains various features.
Square filled ironsIn addition to its durability, most of them have superior qualities. One of its most distinctive features is that it can simply take form. In this context, it is very important in terms of welding, cutting, shaping and processing.simplicityoffers. 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 filled irons, within the scope of tensile strengthsThey have a stainless structure.. Therefore, it is used in many different sectors. One of the most preferred areas with its maximum resistance power is undoubtedly the construction sector. On the supports of various structuressquare filled ironsis used. Therefore, construction structures gain a form that is highly resistant to outdoor conditions and possible natural disasters.
Square filled ironsOne of the most widely used industries isscaffolding constructionsis. functionality and superiorcorrosionIt plays an important role in the construction of solid structures with its 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.
Produced in stainless formsquare filled ironsWith its robustness, it is possible to use it in all construction areas, including crane construction. These parts, which are described as rolled products, are preferred in the production of most ornaments. needed during assembly and productionsquare filled ironYou can access them within the scope of our company's high quality.
