To ensure a smooth processing workflow at your workshop, our gl steel coil surfaces can be finished with a customized passivated organic treatment, most notably our transparent or tinted anti-fingerprint (AFP) chemical shield. The AFP coating prevents oils, handling marks, and moisture from staining the bright spangle look during manual unloading or active roll profiling. It also provides a clean, dry surface matrix that enhances the tracking precision of feed machinery, cutting processing downtime.
