Additionally, the opposite side may have light scratches which occur when during the production of sheets and run off down the rolling tables

How Does Stainless Steel Mill Finish Compare To Aluminum Sheet Mill Finish?

a). Stainless Steel Mill Finish

2B is achieved by cold rolling, heat treating, and pickling.

Also, light rolling is applied at the end to achieve a smooth and reflective look.

It provides a basis for other finishes, such as polishing and brushing.

2D is achieved by cold rolling, heat treating, and pickling but does not undergo light rolling.

It achieves a low reflective surface appearance.

 The finish is ideal for industrial and engineering applications.

Stainless steel mill finishes have the following characteristics

  • It is a dull grey finish.
  • Has very few imperfections on the top side.
  • The reverse side may have very few scratches.
  • It is compatible with a further surface treatment to improve the appearance.

b). Aluminum Mill Finish.

Which Color Is Mill Finish Aluminum Sheet?

The standard mill finishes aluminum is a very light grey finish in color.

The aluminum sheet maintains its natural color after coming out of the mill.

Additionally, it is bare aluminum.

Mill finish usually oxidizes with a light white powder (aluminum oxide) when exposed to moisture and air.

No mechanical or chemical finish has been subjected to it as surface treatment.

Will Mill Finish Aluminum Sheet Corrode?

Although aluminum does not rust, it will oxidize.

This oxidation looks like white residue and pitting.

You can prevent oxidation in aluminum, either by anodizing or powder coating.

Oxidation on mill finished surfaces takes place over a long period.

Mill finish aluminum sheet will rust if you do not take proper precautions against electrolysis.

The precautions are proper storage of your mill finish aluminum in a climate-controlled environment and proper maintenance.

Can You Apply Powder Coating On Mill Finish Aluminum Sheet?

Yes, you can apply powder coating to mill-finished aluminum.

Depending on the final application you want to achieve.

The powder is applied as a solid to the aluminum extrusion. As it goes through the oven process. Solid particles fuse to form the film

Powder coating has the following benefits;

  • It gives you a wide range of bright colors to choose from.
  • Powder coating is environmentally friendly
  • Due to its thickness and bonds with aluminum well thus, it does not easily chip off.
  • Powder coating gives the metal a strong  and long-lasting quality finish
  • Powder coating provides a safe environment for the workers. It is less combustible and has a low electrical requirement.

The process of powder coating involves;

i) Pre-treatment of the aluminum surface removes grease, dust, and foreign particles.

Any dirt or grease on the surface of the aluminum will prevent the powder coat from clinging to the sheet metal,

ii) Application of the powder on the aluminum extrusion.

iii) Heating of aluminum profiles in the curing oven for the powder to bond with the aluminum sheet.

iv) Cooling of the extrusion after baking in the oven.

You will end up with a smooth and hardened coating on the aluminum surface.

Is Mill Finish Aluminum Sheet Finish Durable?

Yes, Mill finish aluminum is durable.

It is because of its properties of non-corrosiveness.

Its alloys make the material resistant to rust and other material damages.

Aluminum materials fare well outdoors, even without surface protections or coating.

Due to aluminum oxide forming on the aluminum surface, a natural layer is added to the metal surface.

It protects the aluminum sheet making it last longer.

How Do You Manufacture Mill Finish Aluminum Sheet?

  • Aluminum sheet slabs are heated to over 400 degrees Celsius. It makes aluminum malleable for the mill to process but not molten,
  • The sheet is then taken through a breakdown mill.
  • The sheet is fed back and forth at the breakdown mill to decrease its thickness.
  • The mill finish is the natural surface left on the sheet surface after the process.
  • Mill-finished aluminum sheets can be further finished in various ways.
  • These include anodizing, powder coating, brushing, and polishing.
  • These finishes protect against corrosion and a better look to aluminum sheets.
