Mill finish aluminum profile
Mill finish is basically bare aluminum, it is the natural appearance of the aluminum, the extrusion profiles without any surface treatment as it comes from the extrusion die, it is simple products after the extrusion processing. The appearance is natural color of aluminum in sliver, as without any surface treatment, there will be some die lines as surface texture, but without any external mechanical or chemical finishing or colouration.

Mill finish is the natural surface texture of aluminum after it comes out of the extrusion die. It usually has a silver color and it is commonly referred to as untreated aluminum. Although various surface treatments may be applied to improve the appearance and durability of aluminum, mill finish is just plain aluminum.

Our extrusion process produces high quality mill finish aluminum. All profiles come out smooth and uniform because of our carefully monitored production process. The extrusion dies are carefully maintained so they enhance the smoothness of the profile surface. so the mill finish aluminum profiles look attractive and they are suitable for internal construction work or for windows and doors in areas where people will have frequent contact with them.

After the extrusion die has produced the aluminum into the desired size and shape, the material is in the mill finish state. Aluminum extrusions are manufactured by pulling or pushing the aluminum stock through a pre-heated steel mould, and aluminum rods are in softened state in stove, the extrusion process can create many different aluminum profiles shapes.

Most mill finish aluminum products usually have longitudinal lines of different width, tone and texture. They may also have surface abrasions. These features are usually highlighted in the description of standard architectural grade aluminum.

Mill finish may not have the same smoothness and appearance of surface-treated and architectural grade aluminum but it is still useful for a wide range of construction projects and fittings. When there is no need for close attention or scrutiny, mill finish serves as one of the most economical types of aluminum profiles for building and construction work.
