Abstract
A decorative roll-patterned metal strip or sheet, preferably aluminium strip or sheet, having: a thickness of about 0.05-1.0 mm, preferably about 0.1-0.8 mm, with a surface having a plurality of indentations of a depth of about 0.001-0.05 mm, preferably about 0.02-0.035 mm, and optionally having a layer of a paint of a thickness of about 3-30 microns, preferably about 10-15 microns, on the surface and within its indentations, the ratio of the depth of the indentations to the thickness of the strip or sheet being in the range of about 1:5 to about 1:100. A process is provided for making the decorative roll-patterned metal strip.
Claims48
A decorative roll-patterned metal strip having a thickness of about 0.05-1.0 mm and a surface having a plurality of indentations of a depth of about 0.001-0.05 mm, wherein the ratio of the depth of the indentations to the thickness of the strip is in the range of about 1:5 to about 1:100.
A process for making a decorative roll-patterned metal strip having a thickness of about 0.05-1.0 mm with a surface having a plurality of indentations of a depth of about 0.001-0.05 mm. wherein the ratio of the depth of the indentations to the thickness of the strip is in the range of about 1:5 to about 1:100, said process comprising the steps of:
- cold-rolling a metal strip at a temperature of about 40-175 C to reduce the thickness of the strip by about 15-40% to about 0.05-1.0 mm, using a milling roll with a surface pattern thereon, to form a roll-patterned strip having, in a surface, a plurality of indentations corresponding to the surface pattern of the milling roll, said indentations having a depth of about 0.001-0.05 mm, wherein a ratio of the depth of the indentations to the thickness of the strip is in the range of about 1:5 to about 1:100.
A process for making a decorative roll-patterned aluminium strip having a thickness of about 0.1-0.8 mm with a surface having a plurality of indentations of a depth of about 0.02-0.035 mm, wherein the ratio of the depth of the indentations to the thickness of the strip is in the range of about 1:5 to about 1:100, said process comprising the steps of:
- cold-rolling an aluminium strip at a temperature of about 40-175 C to reduce the thickness of the strip by about 20-30%, to about 0.1-0.8 mm, using a milling roll with a surface pattern thereon, to form a roll-patterned strip having, in a surface, a plurality of indentations corresponding to the surface pattern of the milling roll and with a depth of about 0.02-0.035 mm, wherein a ratio of the depth of the indentations to the thickness of the strip is in the range of about 1:5 to about 1:100.
