Metal structures

Metal structures manufacturing

 The main activity of PROTOS LLC is the production of wide-range metal structures for the construction of buildings and structures for various purposes and the degree of complexity.

Metalwork factory

Metalware plant Protos LLC, commissioned in 2014, has the capacity of a production base that allows to produce up to 1500 tons of finished products per month, which is enough to simultaneously supply 3-4 construction sites.

Types of manufactured steel:

  • Bridge metal structures for road and railway bridges;

  • metal girders, towers, columns, poles, piles, and other elements of metal buildings carcasses of industrial, agricultural and warehouse use;

  • Metal structures for civil facilities: shopping and entertainment complexes, sports and health centers;

  • Non-standard metal constructions;

  • Lighting masts, fences, overpasses, etc .;

  • Embedded parts, anchor blocks;

  • Steel structures for hazardous production facilities, petrochemical complexes;

  • Unique large-sized construction according to the customer's drawings, which require high accuracy of manufacturing and installation.

Metal structures manufacturing

Metal structures manufacturing is carried out with the use of modern metalworking, crane and welding equipment of the world's leading manufacturers, analogues of which at the moment are not equipped with any metalware factory in the Republic of Belarus.

Quality assurance

Quality control is carried out by OTC and its own Laboratory of Nondestructive Testing using the method of thickness measurement, visual-optical and ultrasonic methods of control for welded joints. The laboratory has the certificate of the National Accreditation System of the Republic of Belarus No. BY / 112 2.4700 dated 16.10.2015.

The quality of welding operations due to their complexity and responsibility is regulated by the state. Mandatory certification of NACS (National Welding Control Association) is subject to:

- welding technology,

- equipment for welding,

- welding consumables,

- welders.

LLC "Protos" has all the relevant NAKS certificates.

Installation of metal structures

The installation of structures with a metal frame according to modern technologies implies the maximum degree of factory readiness of structures in conditions of full-scale factory production using high-tech equipment with mandatory quality control at each production stage.

The 3D model of the object, developed by the project department of Protos LLC, can be used on the installation site to speed up the installation.

Production cost formation

The price of metal structures is calculated on the basis of the documentation set of the CM cipher provided by the Customer and includes:

  • Cost of rolled metal, not less than 70% of the cost of finished products. Materials are purchased under direct contracts directly from the leading manufacturers of the Republic of Belarus, the Russian Federation, Ukraine, the European Union

  • The cost of developing the documentation of the cipher KMD and technological documentation for production

  • Cost of welding and auxiliary materials

  • Cost of anticorrosive protection

  • The cost of a set of mounting hardware (if necessary)

  • Cost of delivery of finished goods to the customer's site using own long-distance transport (if necessary)
