15 Forming of EVALON® coated metal sheets

EVALON® coated metal sheets:

  • steel sheets, 0.6 mm thick, galvanised
  • coated with a light-grey protective lacquer (10 μm thick) on the back side
  • laminated on the top side with 0.6 mm EVALON®
  • sheets (1 m x 2 m) or coils (1 m x 30 m)
  • overall thickness 1.2 mm

Coated stainless steel sheets:

  • stainless steel sheets, 0.6 mm thick,
  • laminated on the top side with 0.6 mm EVALON®
  • sheets (1 m x 2 m)
  • overall thickness 1.2 mm

Coated metal sheets are packed in the factory and transported on pallets. They must be stored horizontally on a dry and plain area.

The forming (cutting, bending) of coated metal sheets should be done at room temperature (approx. 18 °C).


 

15.1 Cutting

The coated metal sheets should be cut with sharp tools with the protective lacquer coating up. This makes a deburring of the sheets unnecessary. The cutting clearance should be 0.03 mm to 0.04 mm.

15.2 Bending

EVALON® coated metal sheets can be bent on any standard bending machine. The bending radius should be 1.2 mm – 1.8 mm.
Attention! Ensure that the EVALON® coating is in the correct position.

Coated metal angles for valleys are to be bent with an angle which is approx. 10° – 15° wider than the required angle. This will guarantee that the coated metal angles will fit closely to the substrate when fastened.

With coated metal strips the same effect will be reached by reverse bending.
