Our offer - Meshes (wire meshes and expanded metal) - Expanded metal - Possible effects of cutting and expanding process
POSSIBLE EFFECTS OF CUTTING AND EXPANDING PROCESS
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.
Sketch 9. Distortion
Distortion of rectangular shape is permitted for the nets without final cutting. It can be up to 2% of the sheet edge length.
FLATNESS OF EXPANDED METAL
Expanded metal mesh is deemed as flat, if arranged on smooth surface does not show curve higher than 30mm, on width 1000mm (3% of the width). For stainless sheets "f" values amounts 50mm (5%). For heat- resistant sheets "f" value can not be determine. Other requirements must be predetermine before ordering.
Sketch 10. Bulge "f" of the nets along to the width W
Sketch 11. Bulge "f" of the nets along to the length L
FLATTENING OF INITIAL THICKNESS
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.
