See in a few minutes what we do and how we work.
Engineering
We turn your concept or the architect’s drawing into a structure that can be built and installed without surprises. Steel and aluminium.
Technical, execution and workshop drawings
Complete documentation for production and for your installation crew.
Static and strength calculations
A structure sized for its loads, not by guesswork.
Precise production documentation
Flat patterns, part lists and markings ready for production.
Assembly instructions
Clear instructions that make installation fast and phone-call free.
Laser cutting
A single perforated panel with an intricate pattern or a thousand identical brackets. We cut sheet, tube and profiles with clean edges and consistent accuracy.
| Machine | Type | Power | Max. format | Max. thickness |
|---|---|---|---|---|
| Bystronic ByStar Fiber 4020 | fibre sheet laser | 12 kW | 4000 × 2000 mm | steel, stainless steel, aluminium 30 mm; brass 15 mm; copper 12 mm |
| Bystronic BySprint Pro 3015 | CO₂ sheet laser | 4.4 kW | 3000 × 1500 mm | steel 20 mm; stainless steel 12 mm; aluminium 8 mm |
| BLM LT 8.10 | 3D fibre tube laser | tubes Ø12 to Ø240 mm, profiles 12 to 240 mm | wall thickness 12 mm |
The 3D laser handles tubes and open profiles up to 40 kg/m and 6.5 m long, cuts bevels up to ±45° and measures every profile as it works, compensating for bends and twist. In stock: S235 and S355 steel (0.5 to 20 mm), stainless steel 1.4301 (0.5 to 12 mm, 2B, BA, 4N), aluminium EN AW-5754 and EN AW-1050 (1 to 10 mm), galvanized steel and brass. We quote from DXF or DWG files.
CNC bending
Three Bystronic press brakes cover everything from small angles to facade profiles over three metres long.
| Machine | Force | Max. bending length | Sheet thickness |
|---|---|---|---|
| Bystronic Beyeler Xpert 250 | 250 t | 3100 mm | 0.5 to 12 mm |
| Bystronic Beyeler Xpert 100 (Fast Bend+) | 100 t | 2500 mm | 0.5 to 10 mm |
| Bystronic Xpert 80 | 80 t | 1530 mm | 0.5 to 10 mm |
The stroke of the Xpert 250, extended by 200 mm, bends deep multi-sided parts with flanges up to 260 mm. Achievable thickness depends on bending length and radius. A well-designed bend often replaces a weld, which lowers cost and shortens lead time.
Welding and riveting
Series go to our RoboArc_D robotic cell, complex one-offs to our qualified welders. Certified to EN 1090-1 (execution class EXC2) and EN ISO 3834-2.
Big, heavy parts in one clamping
Frames, consoles and assemblies up to 3000 × 2400 mm and 2 t are welded without repositioning, so they keep their geometry.
Two stations, shorter lead times
While the robot welds on one side of the positioner, we load the next part on the other.
Part 500 looks like part 1
Repeatable weld quality across the whole series, documented within our EN 1090 and EN ISO 3834 system.
Manual welding and riveting
Special parts and prototypes are welded by experienced, fully qualified welders.
RoboArc_D welding robot
| Parameter | Value |
|---|---|
| Robot reach | up to 3150 mm |
| Positioner load capacity (per side) | 125 to 2000 kg |
| Max. part size on the positioner (per side) | 3000 × 2400 mm |
| Cell size (largest positioner version) | 6000 × 4500 × 2500 mm |
Surface finishing
We coat in our own powder coating plant, so we control the finish ourselves and nobody else’s schedule decides your delivery date.
Powder coating (QUALICOAT)
Any RAL colour, matt or gloss, parts up to 3000 × 1500 × 850 mm. The same shade in every batch.
Chemical pretreatment
Degreasing with phosphating, rinsing in demineralised water, passivation. Baths are checked daily.
DUPLEX system
Zinc protection combined with a powder coat for the longest corrosion protection.
Hot-dip and electro-galvanizing
Hot-dip to EN ISO 1461 and electro-galvanizing to EN ISO 2081 at qualified partners. We organise it, check it and take responsibility.
DX51D+Z pre-galvanized sheet
Hot-dip galvanized coil (EN 10346) for bent parts and panels.
Polishing
Finishing of stainless steel and aluminium parts.
Marking, packing and delivery
Marking for assembly
On multi-part orders every piece carries a mark matching the assembly drawing. No sorting pallets on site.
Packed for the route
Pallets, edge protection, wrapping. We match the packaging to the product and the journey.
Trusted logistics partner
Safe, on-time delivery at a reasonable transport cost.
Dates that fit your schedule
Delivery dates are agreed individually to match your project plan.
