Industrial steel fabrication & custom steelwork

From a single prototype to larger runs — send us CAD files, sketches or samples and our workshop will make parts and structures to your specification.

Steel fabrication

What our machines can make

Typical parts we make on our own machines — on their own or combined into welded assemblies.

WorkTypical partsMachinesSize
Cold-formed profilesL-angles, U-channels, C and Z sections, omega (hat) sections, edge trims and custom profiles to drawingCNC press brakeUp to 3100 mm long, 135 t bending force
Bent sheet-metal partsBrackets, covers, machine guards, housings, trays and chutesCNC press brake, CNC plasma cuttingBending length up to 3100 mm
Plasma-cut partsBase plates, flanges, gusset plates, brackets, wear plates and parts nested from DXF filesCNC plasma cutting machineConfirmed per drawing
Rolled partsCylinders and shells, pipe sections from plate, ducts, hopper and silo shells, curved segmentsFour-roll plate bending machineConfirmed per drawing
Cut-to-length stockBars, tubes and profiles cut to length for welding or machiningBand sawRound stock up to Ø350 mm
Machined partsShafts, axles, pins, bushings, spacers, flanges, pulleys, threads, keyways and drilled holesLathes, milling and drilling machinesConfirmed per drawing
Welded assembliesFrames, skids, platforms, hoppers, chutes and machine guards built from the parts aboveAll of the above, plus weldingConfirmed per drawing

Sizes come from the machine nameplates. The maximum thickness depends on the material and the shape — send the drawing and we will confirm it.

One workshop, from drawing to delivery

Our workshop in Cherven Bryag handles the whole job: reading the drawing, cutting and forming the steel, welding, assembly and surface finishing. It is the same workshop that builds our concrete batching plants, so it is used to heavy structures and precise work to drawing.

Parts that keep machines running

Alongside structures we make heavy-duty chains, rollers, shafts, gears and bushings for industrial equipment — as replacements for worn parts or to a new design.

Questions & answers

Do you take one-off orders?

Yes. We produce single prototypes as well as larger runs.

What files can we send?

CAD drawings are ideal; sketches with dimensions, photos or physical samples also work.

Do you make cold-formed profiles?

Yes. On our CNC press brake we bend L, U, C, Z and omega profiles and custom sections from sheet, up to 3100 mm long. Send the cross-section, length, material and quantity.
