Sheetmetal and profile processing

Engineering parts made of sheet metal, profiles and welded assemblies are the core production program of Dendera a.s. These are structural parts for the manufacture and assembly of machinery and equipment, as well as cover parts for the manufacture and assembly of machine covers, produced in bodywork quality.

Laser cutting

For laser cutting we make use of CO2 laser Amada FO3015 and fiber laser Amada Ventis 3015.

The maximum thicknesses of the laser are as follows:

Structural Steels

25 mm

Stainless Steels

20 mm


15 mm


8 mm

Bronze and copper

4 mm

All up to a maximum size 3,000 x 1,500 mm.


The parts from stainless steel and aluminium are usually burred at the bottom rim. This can be removed with special grinding machines Timesaver 42 and Timesaver 10. If required a blast grinding unit of the machine Timesaver 42 can unite the surface of the product which then looks as a finely ground one.

Maximal width of the parts

1000 mm

Maximal length of the parts

3000 mm

Laser Cutting of the Profiles

Laser cutting of the profiles can be used for all types of profiles, a maximal size is as follows:


∅ 200 mm


150 x 150 mm

Maximal length of the profile

3000 mm

Profile Cutting with a Machine Saw

We make use of any profile cutting with a machine saw, being it both vertical and under angle, for a preparation of an optimal length of the profile for laser cutting or as an initial technology for profile cutting as a half-finished product for subsequent technological operations. Any burrs that may arise when cutting with a machine saw can be removed thanks to a special deburring machine.

Maximal size of the profile

260 x 260 mm

Maximal length of the profile

3000 mm

CNC - Bending

Apart from the laser cutting there is another important process - CNC-bending with press brakes. For folding we exclusively make use of 6-axis press brake, which ensures high precision and top quality of bent parts.

Maximal usable width for bent parts

3000 mm

Maximal usable thickness for bent parts

15 mm

Maximal press strength

220 tun

Roll Bending

The company is equipped with more types of roll benders for production of roll bent sheetmetal components.

Minimal thickness of roll bent sheet metal

0,8 mm

Maximal thickness of roll bent sheet metal

8 mm

The components from thin sheetmetal components up to 2 mm of thickness can be maximally 1,000 mm long, more than 2 mm thick ones then can be 1,500 mm long.


As for locksmithworks there are following technologies ensuring production of a complex product:

stamping of fasteners
riveting of fasteners
CNC-engraving with a mechanical stylus

Welding and Grinding

The most fundamental products of the company Dendera Inc. are welded assemblies and bigger construction units. The welding is carried out by all methods – MIG, MAG and TIG, welding joints can be openly visible, or can be according to the requirements further adjusted by means of grinding, up to a bodywork quality. Sheetmetal pieces can be joined also by means of a technology called point welding. The connecting material can be fastened to the components classically, too, or it can be fixed with a condenser shooter.

Maximal size of the weldment

3000x1500x1500 mm

Maximal weight of the weldment

800 kg

In case of a small height and width of the weldment the weldment can be up to 7,500 mm of length.


We make machined parts only for our own own welded or assembled sets. Simple components are manufactured by means of a classical lathe or a milling machine, for more complex production we make use of CNC-machining centers or CNC-lathes.

Maximal size of components when using a classical milling machine

600x250x250 mm

Maximal weight of a component when using a classical milling machine

20 kg

Maximal size of components when using a CNC-cutting machine

1000x800x600 mm

Maximal weight of a component when using a CNC-cutting machine

20 kg

Maximal size of components when using a classical lathe

∅ 180x1000 mm

Maximal weight of a component when using a classical lathe

20 kg

Maximal size of components when using a CNC-lathe

∅ 260x600 mm

Maximal weight of a component when using CNC-lathe

20 kg

Surface Treatment

We provide our customers with surface treatment of the components in compliance with their requirements.

We make use of following technologies:

blue galvanization
yellow galvanization
ecological galvanization
zink – nickel
hot dip galvanizing
comaxite with a prefinish of phosphate coating or sandblasting
blasting with glass balls
nickel coating
chromium plating

Please, always consult any particular surface treatment technology with our experienced production workers.
