CONSTRUCTION MATERIALS AND FINISHES
Hayes & Stolz Bucket Elevators can be furnished of mild steel, stainless steel or galvanized construction.
Mild steel units, manufactured entirely of mild steel, will have the complete exterior painted with an industrial polyurethane topcoat (standard color is SW Pillar White) over rust inhibitive primer.
Stainless steel units provide stainless steel product contact surfaces. Exterior stainless steel can be unpainted or painted with an industrial polyurethane topcoat (standard color is SW Pillar White) over stainless-compatible primer.
When galvanized construction is specified head and boot sections will be of mild steel construction and hot-dip galvanized per ASTM A123 specifications prior to assembly. Casing sections are fabricated of galvanized sheet with zinc rich “cold patch” paint over the welds to ASTM A780.
A gland type seal can be added to the boot section to provide additional dust tight measures.
To minimize product build-up, the standard crown faced boot pulley can be substituted with an optional wing type pulley with or without a spiral face.
