Structural steel erection

    "Holding 812" company provides installation of metal structures for pre-fabricated structures for various purposes. The quality of the metal frame directly affects the durability and strength of such structures.

    The company's specialists have deep experience in the construction of metal structures for prefabricated buildings on standard and individual projects within the terms specified in the agreement. Qualified craftsmen may perform the entire range of works, including:

  • design;
  • delivery of metal structures and welding equipment to the construction site;
  • erecting and welding works at height in various conditions.

    We offer affordable prices for welding works. We offer the lowest cost per ton of metal structures welding in the market of Moscow and St. Petersburg.

Features of installation light steel thin-walled structures frames

    This is a universal frame that is used for rapid construction of buildings for various purposes. These types of structures are cost-effective and functional. Thanks to the use of simple installation technology, the customer can save up to 50%, which is required for the construction of monolithic and brick buildings.

    We install a variety of objects on the basis of light steel thin-walled structures frames:

  • frameless;
  • frame and tent;
  • hybrid;
  • portable structures that are connected by bolts.

    Our company's engineers may help you choose the best option of the light steel thin-walled structures for various purposes.

    The benefits of buildings on the basis of light steel thin-walled structures include:

  • erecting works dispatch;
  • affordable price;
  • durability
  • flexibility.

  Pre-fabricated structures based on light steel thin-walled structures have high moisture resistance and good thermal insulation. The construction of a hangar with a total area of 1500 m2 based on this design will take only 3 months, while using traditional construction technologies it would take at least 6 months.

      The use of light steel thin-walled structures allows you to reduce construction costs from 10 to 30% of the budget due to the fact that you do not need to spend on the construction of a solid foundation for such a structure. Compact structures are easy to transport on conventional cargo transport.

  The company has its own production facilities, a database of ready-made projects, and a staff of qualified craftsmen who assemble metal structures.
