Profile: Alusmart.Bobo Ltd is a producer and supplier of aluminum tapered, conical & steel poles. We are an ISO 9001:2000 certified company. Our products include aluminum and street lightning poles, heat sinks & aluminum profiles. Our aluminum tapered poles are applied in path, wharf, airport and public places. Our available surface finishes for aluminum poles include aluminum stain, clear, black & dark bronze anodized. Our clear anodized is a process that coats the shaft with a chemical treatment using an electrostatic process in a chemical bath. The chemical coating adheres to the metal at the molecular level rather than adhering to the surface like an enamel paint finish. Dark bronze anodized is a process of electrolysis. These finishes are recommended in coastal areas and are matches for many building skins.
