Our products and services
Prefabrication of steel structures
Konstalex specialises in the manufacture of heavy steel constructions for the energy industry and for bridge structures.
In addition, we produce light constructions for general construction purposes, as well as specialised structures, both one-off and repeatable.
Our business includes the manufacture of steel structures:
road bridges, railway bridges, footbridges, viaducts
production and warehouse spaces
power plants
welded and bolted structures including machining
Manufacturing capabilities
Depending on the type of steel structure, the plant produces approx. 600 ÷ 1,000 tonnes of structures per month. Structures are manufactured from basic carbon and higher strength steel grades.
We carry out production tasks in the field of:
- plastic, thermal and mechanical processing as well as machining,
- welding of structures: gas welding (135, 136, 131), automatic welding machines (121), electrodes (111),
- corrosion protection: shot-blasting, painting with paint mixtures, thermal zinc spraying and thermal metal spraying.

Transport
The steel construction plant is located in central Poland, with excellent access to expressways – the A1 and A2 motorways. The plant is located 5 km from the Warsaw-Katowice expressway.
The exit gates of the hall allow the transport of elements up to 5.8m wide.
Quality control and modern technologies
Product quality control
Quality control is carried out at each production stage, from the beginning of the manufacturing process to the acceptance of the finished product.
The plant is equipped with a laboratory with the possibility of conducting:
- non-destructive testing (NDT) of welds,
- linear and shape measurements of components,
- geodetic measurements of components, e.g. in trial assembly.
In cooperation with relevant institutions, it performs the following tests:
- chemical composition of metallurgical materials,
- destructive testing of welds.
Technological processes carried out in the plant
Plastic, thermal and mechanical processing
Machining
Shop assembly of steel structures
Welding of structures
Corrosion protection, including spray metallisation
Basic technological processes
The plant’s operations are based on the following departments:
- preparatory,
- assembly and welding,
- anticorrosion coatings,
- auxiliary (energy, mechanical and tool shop).
