Because scaffolding is used high strength of aluminum material 6061-T6, or is 6082-T6 to welding and into, because aluminum itself is more active of metal components, it easy and outside of acid alkali occurred chemical reactions, it if long-term in water in the, aluminum components also will in water in the occurred chemical reactions, to provides scaffolding performance of stability, Yao na stage technician on he for has anti-acid alkali capacity of upgrade, on scaffolding for oxidation processing, makes its surface with has a layer oxidation film, Stop outside the corrosive effects of substances on the scaffold. In order to overcome the aluminum surface defects such as hardness, abrasion resistance, longevity, surface treatment technology of aluminum alloy used is an indispensable part of it. Metal oxide film changes the surface appearance and performance, such as rendering, improved corrosion resistance, enhanced abrasion resistance and hardness to protect the metal surface. Such as aluminum anodizing, electrolyte of aluminum alloy in the appropriate (such as sulfuric acid, chromic acid, oxalic acid, and so on) as the anode, under certain conditions and impressed current, electrolytic. Anodic oxidation of aluminium or their alloys, thin layer of aluminum oxide is formed on the surface, 5~20 microns thickness, Anodic oxidation of aluminium or their alloys, increase its hardness and wear resistance.
