Fabrication of steel structures

welded and bolted steel structures:

level floor jigs for trial assembly of structural steelwork items with a single weight up to 100 tones;
all required welding equipment used in fabrication of steel structures. For fabrication of steel structures for boilers & buildings used are the welding processes as follows: MAG, SMAW and mechanized submerged-arc welding;
plate straightening machine (for plates 3250 mm wide and up to 60 mm thick) for straightening initial plates and pre-welded plates;
special shot-blast plants for steel structure surface preparation before painting and preservation.

The above mentioned welding equipment makes it possible to produce by welding about 400 tones steel structures per month.
