Equipment construction details are an important part of food handling applications. Understanding material surface finishes, weld types, and frame styles are important aspects of design and fabrication choices that go into your equipment selection process.

Stainless Steel Material Surfaces
STAINLESS STEEL SHEET FINISHES
Glass bead blast
No.4 (brush polish)
No. 2B (mill)
Mill Finish
- Surfaces will have an inconsistent appearance with varying uniformity, especially between Sheet and Structural materials
- Will include minor surface scratches
#4 Polished
- Sheet steel surfaces will have a consistent brushed appearance with minor varying uniformity, primarily between Sheet and Structural materials
- Will include minor surface scratches
Glass bead blast
- Specified surfaces are bead blasted which results in a more consistent surface texture with a more uniform deeper gray appearance.
Passivation
- Dissolves free iron impurities and helps restore the corrosion protection provided by the passive surface layer.
- Specified surfaces are passivated after cleaning, grinding, and/or bead blasting processes are completed.
