[0002] Aluminum profile is an alloy material with aluminum as the main component. Profiles with different cross-sectional shapes are obtained by hot melting, extruding and sawing aluminum bars. After processing the water channel on the side wall of some columnar aluminum profiles, the water channel holes on the two end faces need to be welded and sealed.
