„ZAMET BUDOWA MASZYN” has a large fabrication potential and experienced staff aggregated in works in Tarnowskie Góry and Bytom.
Most of the machines are CNC controlled heavy machines (lathes, drilling-milling machines, gantry milling machines)
Weight of machined elements can reach 150T, which elements can be transported with unit cranes of capacity 100T or with two cranes 100T using a special beam. Additionally we are vested with cranes over each machining-assembly areas, with maximum capacity between 5T and 100T.
A company disposes modern welding technologies, enabling fabrication of reliable welded structures, that meet high quality testing requirements, also foreign.
A confirmation of the above are certificates: Qualifying Certificate for I Group of Big Works granted by Welding Institute in Gliwice, Poland and Large Qualifying Certificate in class E, granted by GSI SLV – Duisburg.
