About us
Manufacture of metal structures and their components
LIMOSTEEL" d.o.o. za proizvodnju metalnih konstrukcija i njihovih dijelova Gradačac has been operating successfully since 2016.
We work in metal fabrication, steel structures, fiber laser cutting and CNC press brake bending. Our plant is in Gradačac, at Sarajevska bb, and we carry out work across Bosnia and Herzegovina and the wider region.
A job starts with a drawing — yours or ours, produced from a sketch, a sample or measurements taken on site. From there the part goes through the laser, the press brake and welding without leaving the plant, so there are no mismatched dimensions between subcontractors and no shifting of responsibility when something does not fit.
For steel structures and canopies we fabricate the members in the shop and erect them on site with our own crew. That leaves a single address responsible for dimensions, schedule and quality of work.
Quality is not just a claim: the quality management system and the welding procedure were audited and certified by the German body TÜV Thüringen.

Technical capabilities
A machine park under one roof
Laser, press brake and welding are all in the same plant in Gradačac. The part never travels between companies, so lead time and tolerances stay under control from sheet to finished assembly.
Fiber laser
CNCCutting sheet and tube
Cutting structural steel, stainless steel and aluminium, as well as square and round tube. Work from your drawing, with nesting for maximum sheet utilisation.
- Resonator power
- 3,000 W
- Working area
- 3,000 × 1,500 mm
- Steel (S235 / S355)
- up to 20 mm
- Stainless steel
- up to 12 mm
- Aluminium
- up to 10 mm
- Positioning accuracy
- ±0.05 mm
- Tube
- square and round
- Drawing formats
- DXF, DWG, PDF, STEP
CNC press brake
CNCProgrammed sheet bending
Bending with computer controlled force, angle and positioning. The program stores every bending step, so each part in the batch is identical.
- Manufacturer
- OMAG
- Press force
- 100 t (1,000 kN)
- Bending length
- 3,100 mm
- Control
- CNC, graphical programming
- Back gauge
- multi axis
- Angle repeatability
- ±0.1 mm
MAG welding
WPQRQualified procedure (WPQR)
Welding is carried out to a welding procedure qualification verified by TUV Thuringen. Every figure in this table is taken from the WPQR document.
- Process
- MAG 135 (ISO 4063)
- Parent material
- group 1 steels (ISO/TR 15608)
- Yield point
- up to 355 MPa
- Material thickness
- 6.0 – 24.0 mm
- Filler metal
- G3Si1 (ISO 14341-A)
- Shielding gas
- M21 (ISO 14175)
- Welding positions
- PA, PC, PF
- Joint type
- fillet weld, multi layer
The welding data is taken from the welding procedure qualification record (WPQR Z-64012/18, TUV Thuringen). For exact laser and press brake capacities please contact us — dimensions and thicknesses are verified before a quotation is confirmed.
Why Limosteel
Six reasons you can verify
No general claims. Every item below is something visible on a document, in the plant or on a completed building.
01
Our own machine park
Fiber laser, CNC press brake and welding equipment under one roof. No waiting on a third party and no passing responsibility between subcontractors.
02
Qualified welding
MAG process qualified through a WPQR verified by TUV Thuringen, alongside certification of the welding quality system to DIN EN ISO 3834-3.
03
From one piece to a series
With no tooling cost a prototype is viable even as a single piece, and the program is saved for every later order of the same part.
04
Work from your drawing
DXF, DWG, PDF and STEP. If there is no drawing, we produce it from a sketch, a sample or measurements taken on site.
05
Experience since 2016
Completed structures on production halls, long span canopies, commercial and service buildings.
06
Fabrication and erection
Members are fabricated in the shop and erected by our own crew — one address from drawing to finished building.
Quality and certificates
Documents issued by TÜV Thüringen
The quality system and the welding procedure were audited and certified by the German certification body TÜV Thüringen.
DIN EN ISO 3834-3:2006

WPQR — Z-64012/18
The welding procedure qualification (WPQR Z-64012/18) covers the MAG process on group 1 steels up to 355 MPa, thicknesses 6.0 – 24.0 mm, in positions PA, PC and PF — the range in which most load bearing steel structures are made.
