CHINA UNITED IRON AND STEEL LIMITED is one of the notable and esteemed manufacturers of ST52-3 Square Tube used due to their excellent features and performance. Being the leading manufacturers of square tubes we aim to manufacture tubes in such a way that it can easily fulfill all the requirements and demands of customers. These square tubes are widely used in several applications and offer the best performance. We at the time of manufacturing these tubes make use of top-notch quality of raw material which is tested and inspected as per the international quality standards.
Product details

ST52-3 is a low alloy steel that is known for its high tensile strength and corrosion resistance properties. It is used for manufacturing various applications and offer capacity to withstand in high temperature and pressure. For manufacturing these square tubes, top notch quality of raw material is used that is well inspected and tested so that it can provide its best in the respective areas of working. Furthermore, advanced machines and latest tools are used for manufacturing these square tubes. We even use national specifications and some international standards for creating a high quality of products.

These square tubes have various attributes which makes them even more demanding among various industrial applications. The features include excellent corrosion resistance, durability, workability, weldability, high tensile strength, ductility, and long service life. Furthermore, there are various tests and inspections done so as to check the quality of these tubes.
Testing and packaging

As said in the above paragraph that these square tubes are tested to check the quality so these tests include flaring test, flattening test, visual inspection, radiography test, hardness test, corrosion resistance test, durability test, third-party inspection and more. There are some more tests done like a destructive test, non-destructive test, macro, and micro test. All these tests are done under the guidance and supervision of experts that in turn provide quality test certificates proving products quality and durability.

At last, the packaging process takes place, where the ST52-3 Square Tube is packed in high and superior quality of packaging material which in turn helps prevent rust and damages until its last stage of production.
