In order to build a better truss system Rk keep research on surface treatment technology,and now its becomes an indispensable part in using aluminum alloy truss.it is to overcome the aluminum alloy truss with surface hardness, wear resistance.extend the service life.

Metal oxide thin film changes the surface state and properties, such as surface color, improve corrosion resistance, improved wear resistance and hardness, protect the metal surfaces. For example, anodized aluminum, the aluminum in the appropriate electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, in certain conditions, and under the action of applied current for electrolysis. Anodic oxidation aluminum or an alloy thereof, those are formed on the surface of thin aluminum having a thickness of 5 to 20 microns after anodizing aluminum or alloys, improved hardness and wear resistance.

Because truss systems are made of high strength aluminum alloy 6061-T6, 6082-T6 or to weld together, since the aluminum itself is more active metal component, it easily with the acid-base chemical reactions outside it if long-term in the water, the aluminum composition will react in the water, in order to provide the stability of performance aluminum truss, stage truss RK was the first stop on his technician had the ability to enhance the anti-acid, oxidation treatment on the aluminum truss to the surface with a layer of oxide film, preventing the foreign matter to the corrosive effect of truss.
