-ISCIR according CR2/2003
2. Heat treatment after welding: stress relief (dimensions 4000x8000x2600mm / max. weight : 30 t)

3. Corrosion protection of welded structures: sandblast, priming, painting, chromium plating, galvanizing, phosphating

Types of Products: Medium and heavy welded structures of various complexities:

Execution of non-alloy steel for welded structures, fine grain steels, steels for low temperature or high temperature. Overall dimensions up to (WxDxH)-25000x5000x4000 mm max of 50 to:
– Substructure for drilling mast; structures for offshore
– Stinger boom
– Beam road bridge, beam bridge crane type or rider
– Housing of gear  reducers, winches, mud pumps
– Wheels
– Drums

Welded structure can be stress relief.
