OEM Building Interlocking Aluminum Extrusions Aluminum parts often pick up a dull, flaky oxide layer after extrusion. That layer spoils surface quality. It also risks coating failures and customer complaints. Good removal standards require the surface to be clean, smooth, and ready for finishing before any coating or anodizing.
