  • Facade cladding

Production of heat exchangers

Our company has experience in making heat exchangers. So far, we have produced over 65t of black and stainless steel heat exchangers. We make products for both domestic and foreign markets.

Construction of bridge cranes

Bridge cranes are used for cargo handling in production halls, workshops, storage space, etc.

Depending on the required load capacity, installation possibilities and range, we offer the production of:

  • Bridge cranes (single-row and double-row)
  • Crane tracks
  • Portal cranes

Construction of public facilities

Steeltec offers the design and manufacture of all types of steel structures for public facilities, such as hospitals, open and closed sports facilities, traffic light portals, level pedestrian crossings, markets and the like.

Special constructions (silos, tanks and cisterns)

Silos, tanks and cisterns are made in various sizes and shapes according to the needs of the Investor. They can be made of different materials such as stainless steel (aluminum), aluminum, black steel (.

Most of these assemblies are made as pressure vessels, for which our company has experience in production.

Steeltec has the ability to process high quality components of various sizes, materials and specifications. Cutting, mowing and drilling can also be automated with superior precision. Using state-of-the-art CNC machines and qualified operators, Steeltec offers:

  • High-precision CNC lathes for turning pieces up to 2.5 m long
  • Gas and plasma cutting plates up to 200 mm thick
  • Precision drilling, grinding and milling
  • Slab contraction joints (width up to 3 m and thickness 10 mm)
  • Manual cutting of edges for preparation of welds


Welds are one of the most important characteristics of steel construction and expertise, knowledge and experience greatly contribute to the assurance of the structure:

  • Welding of different materials and special types of steel
  • IWE / EWE qualified welding engineers
  • International standards and welding codes: AWS, ASME, API, BS, ISO, CEN
  • Manual, semi-manual and automatic welding
  • Welding technologies: MIG / MAG, TIG
  • Non-damaging test (NDT)


Steeltec offers bending of steel plates up to 120 mm thick:

  • Double submerged arc welded pipes (DSAW – UOE method, JCOE method), Spiral welded, seamless
  • Plate thickness – up to 120 mm
  • Slab width – up to 3 m


Steeltec can offer a wide range of high quality steel parts:

  • Lengths – up to 4 m
  • Bending force up to 2000 mt
  • Thickness – up to 20 mm
  • Large range of press tools
  • Large throat area for a wide range of shaping dimensions

Semi-automated material handling for efficient and safe shaping


A quality coating system, whether with protective paint or galvanizing, is important for the aesthetics and durability of the steel structure. Steeltec offers a wide range of available coating system options to suit many projects. Another aspect that is often overlooked is the packaging system that Steeltec offers to ensure that your product arrives at your location with minimal or no damage to the coating.

  • Combination of manual and semi-automatic application methods for consistent thickness and ability to apply in hard to reach places
  • Sandblasting according to different standards
  • Various coating options – colors, types
  • Careful control of humidity and temperature


Testing at all stages of development is crucial in the quality assurance process. All products manufactured by Steeltec follow a strict inspection and test plan with different retention points to check the components for strength and defects. Steeltec offers a complete package and expertise in testing steel structures:

  • Highly accurate, routinely calibrated and certified dimensional measurement equipment
  • ISO, EN 1090, ISO 3834 and other certificates
  • Close relations with reputable independent engineers for testing of welded joints MT, RT, PT, VT
  • Coating overview – thickness, imperfections, adhesion


Steeltec offers clients a dedicated project engineer for every order, communication and technical inquiries. This makes project management easier for both the company and the clients. We understand the need for close interaction with contractors, design consultants, owners and other stakeholders in the project.
