Recommended minimum flange length and inside radius
If the flange has a notch, the shortest side should be taken as the flange length. See metal folding diagram. The danger of such parts is that the shorter part of the flange deforms during bending.
When you have successive bends, the minimum distance is the minimum flange length. See metal folding diagram.
Use cut-outs next to the flanges to prevent tearing of the material during bending.
Maximum sheet dimensions - 2990 x 1490 mm
Although the standard sheet size is 3000 × 1500 mm, we need to cut the edges to ensure the correct positioning of the cut-outs.

Cutting letters and characters
Variants of the letter "O". Version 3 will end as version 1. It just has an unnecessary extra cut.
The interior of the letters will fall out if it is not related to the work. This is a common mistake we see.
Cut to "normal"
Distance between holes
Size of holes
With new fibre laser technology, we can cut holes smaller than the thickness of the material!
Add a radius to the pipe
General rules for the radius:
- Radius measurements of corners of rectangular and square hollow section (SHS, RHS).
- Radius dimensions for hot and cold rolled rectangular (RHS) and square hollow section (SHS) tubes are hidden in their respective BS EN dimensional and tolerance standards.
Maximum pipe dimensions
The maximum length for cutting pipes is 4500 mm.
No holes in the radius of the pipe
All drawings must be 1:1. Copying the dimensions will not help.
Create your drawing from scratch
“Save as” files often bring with them unnecessary hidden layers or unnoticeable views from a distance. Create a new drawing instead of using the old one as a template.
One piece per drawing
Connected Lines - Connect the lines
"Splines" can cause a lot of problems. Laser cutters have their own software that interprets splines in a way that gives an unsatisfactory result. Use arcs and lines instead. They are easily readable by laser cutting software.
No overlapping lines
They may be hard to see with the human eye, but the computer recognises them and cuts them out as additional cuts.
