Rectangular and square tube is one of the types of modern construction rolled metal products.
There are different technologies that used in production of these types of products. The first one is direct shaping of tube profile from flat blanks (strips). Due to this method manufacturers can use simple production equipment, reduce power consumption significantly and use more narrow and light blanks. All these facts result in considerable improvement of process economics. However, there are no miracles and such tubes have some disadvantages, namely: uneven distribution of stress along cross section, considerable reduction of tube body at stress concentration zones (at elbows). Thus, the products, manufactured in such way, have doubtful quality. Therefore these tubes are prohibited in many developed countries.
We use modern technology that provides for creation of evenly stressed welded round blanks of set diameter at the first stage with further secondary pressure treatment in the group of special rollers where it gets special profile cross-section of necessary size and shape. This technology allows manufacturing products that are free from above-listed defects. In accordance with standards the weld joints of tubes are subject to 100% non-destructive tests and, in some cases, thermal treatment for removal of internal mechanical stresses.
Rectangular and square tubes manufactured at our enterprise certified in accordance with international standards DIN EN 10219-1:2006.
