Finish

Chrome

This finish improves appearance and provides mild corrosion resistance. It can also increase surface hardness, which improve abrasion resistance, reduces friction, and prevents seizing. This finish is shiny and aesthetically pleasing.

Plain

Nothing has been done to this bare metal surface to improve appearance or corrosion resistance, which is very low if the material is steel. Often the surface has been oiled which improves lubricity. This finish is susceptible to rusting and corrosion in exterior environments. This most basic finish can be used when protection is not an issue or indoors.

Material

Alloy Steel

Alloy steels contain one or more alloying elements in addition to carbon in percentages beyond a specified threshold. These steels are produced for use in specific applications, having a certain degree of corrosion resistance, hardness, strength, ductility or other desired property not found in typical carbon steels or stainless steels.
