Energy facilities and substations

The production of structures for energy industry construction projects accounts for 60% of the production capacity of ASLA.

We are a supplier of main steel structures (MSS) and auxiliary steel structures (ASS) to high (HV) and very high voltage (VHV) substations throughout the Czech Republic and Slovakia. For example, we implemented the construction of entire OK units for TR Prosenice, TR Výškov, TR Přeštice and others. This segment and the satisfaction of energy construction suppliers is our priority.

Another segment we focus on are high voltage pylons and street lighting.
