One inch aluminium flat bar

   The original surface of aluminum profiles generally has a self oxidation film, and even slight scratches may occur during raw material transportation.  Before surface treatment of aluminum, aluminium profiles go through processes such as processing, forming, heat treatment, and storage, as well as some of dust sticking. In order to improve the decorative effect of surface treatment and ensure the smooth progress of subsequent aluminum surface treatment main process anodizing, surface pretreatment of aluminum is indispensable.  The alkaline washing process involves placing aluminum profiles in a strong alkaline solution mainly composed of sodium hydroxide for etching reaction. The purpose of this process is to further remove surface impurities, thoroughly remove the natural oxide film on the aluminum surface, and expose the metal substrate, laying a good foundation for the subsequent surface treatment technology of anodizing to generate a uniform anodized film. If the alkaline washing time is appropriately extended, it can also make the surface of the aluminum profile tend to be flat and uniform, eliminating rough marks on the surface of the aluminum material. Long term alkaline washing can obtain a uniform and soft diffuse reflective surface without strong reflection.

  Flat bar Aluminium Profile is a type of aluminum alloy material with a flat shape. Aluminum Extrusion Profile has good corrosion resistance and can be used in various environment, making it less prone to rust and corrosion. One inch flat aluminum profiles can be extruded according to your technical drawings. Flat bar aluminium profiles are easy to process and install, and can be processed and assembled through cutting, drilling, welding, and other methods, making it convenient to meet various shape and size requirements. One inch flat bar aluminum profiles are often used to make various structures, frames, brackets, decorative materials, etc.,and Standard Aluminum Extrusion Shapes are widely used in industries such as construction, machinery and electronics.
