CONSTRUCTION MATERIALS AND FINISHES
All Hayes & Stolz Distributors can be furnished of mild steel, stainless steel or galvanized construction.
Mild steel units, manufactured entirely of mild steel, will have the interior and drive chamber primed with a rust-inhibitive primer and the complete exterior painted with an industrial polyurethane topcoat (standard color is SW Pillar White) over rust inhibitive primer.
Stainless steel units are standard with stainless steel bodies and internal product contact surfaces, with mild steel construction inside the drive chamber which is isolated from the product contact zone. The mild steel in the drive chamber is primed with rust-inhibitive primer. The stainless steel exterior 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 all fabricated components will be of mild steel construction and hot-dip galvanized per ASTM A123 specifications prior to assembly. (NOTE: Larger units may be fabricated of galvanized sheet with zinc rich “cold patch” paint over the welds to ASTM A780.)
