POSSIBLE EFFECTS OF CUTTING AND EXPANDING PROCESS

 

rys.8 siatka dekoracyjna

Sketch 8 Decorative expanded metal

 

 

Expanded metal mesh has got two sides: the front one (decorative) and technological. On technological side some scratches may occur as an effect of production process.

 

ATTENTION: For decorative applications (elevation/panels) it is suggested to mount nets on whole wall according (along) to the cutting process of sheet and strictly using as an external surface correct side of nets (front side). Correct method of mounting is especially important for nets with thick bridges (c).

 

 

 

For the parameters listed below we apply tolerance according to the norm PN-EN 10051:2011.

 

rys.9 lukowatosc

 

Sketch 9. Distortion

 

Distortion of rectangular shape is permitted for the nets without final cutting.

 

 

FLATNESS OF EXPANDED METAL

 

Expanded metal mesh is deemed as flat, if arranged on smooth surface does not show curve higher than 20mm, on width 1000mm. For heat- resistant sheets "f" value amounts 40mm.

 

rys.10 wybrzuszenie po W

 

Sketch 10. Bulge "f" of the nets along to the width W

 

 

rys.11 wybrzuszenie po L

 

Sketch 11. Bulge "f" of the nets along to the length L

 

 

 

FLATTENING OF INITIAL THICKNESS

 


rys.12 splaszczenie

 

Sketch 12. Flattening of initial material (example : g=2mm)

 

In some cases during cutting process on the areas without any material's support cross section of metal changes and becomes flattening what has an impact on final thickness of expanded metal. On the supported areas final thickness becomes thinner only for 0,1 mm. This occurrences are caused and imposed by technology of production.
