How is the brushed effect achieved on the ACP surface?

A: The brushed effect is created by a mechanical process that directionally and continuously abrades the aluminum surface. Two main methods: 1) Physical Brushing: Using machinery with abrasive belts to grind the aluminum surface in a single direction, creating uniform linear textures (hairline). 2) Chemical Etch Brushing: Using chemicals to corrode the aluminum surface, forming a similar, potentially more uniform texture. Afterwards, a transparent or colored protective coating (e.g., PVDF) is applied over the brushed surface.
