About Us in Brief

ACL Anodizing s.r.o. is located in Jablonec nad Nisou and specializes in the surface treatment of aluminium and aluminium alloy products by way of anodizing. Anodic oxidation of aluminium or its alloys creates an aluminium oxide layer with a corundum-type microcrystalline structure on a part’s surface. This very hard, non-conductive, and wear-resistant layer protects the surface of the part from subsequent oxidation.
