As well as railings and fences, we can make large metal structures like this staircase that spans 4 floors and weighs more then 16 tons.
It is a modular structure, each floor having a corresponding module that are installed one on top of another. The support posts are 220X220 and 10mm thick.
The roof of each module is cut out of corrugated tin reinforced with 220mm I beams.
The transport of these modules to the customer required the usage of wide load trucks.
To mount them, a 45 tone Krupp crane mobile crane was used. It took 8 hours to mount them because the attention that was paid when fabricating the modules.
I will now present to you different stages of the assembly and installation.
