Commercial Stainless Steel Flanged Bumper
Architectural Hardware / Industrial Fixture · Unknown Industrial Manufacturer (High-volume commercial hardware supplier)
Pattern: Standard Commercial Utility / Industrial Series
Type
Architectural Hardware / Industrial Fixture
Maker
Unknown Industrial Manufacturer (High-volume commercial hardware supplier)
Material
Cast or machined Zinc alloy (Pot Metal) or Aluminum, potentially Chrome-plated. No silver content.
Dimensions
Diameter approx. 2.5-3 inches; likely weighs 150-300 grams depending on alloy density.
Description
A utilitarian wall-mounted bumper or door stop typically found in restrooms or commercial kitchens. It features a circular flange and a tiered conical body ending in a textured face.
Key Features
Phillips-head screw mounting, concentric circle face design, flanged base, satin metallic surface.
Material & Composition
Cast or machined Zinc alloy (Pot Metal) or Aluminum, potentially Chrome-plated. No silver content.
Finish & Decoration
Brushed or satin metallic finish with concentric ring texture on the face; exhibiting severe pitting and corrosion.
Hallmarks & Stamps
None visible. No precious metal hallmarks; standard Phillips-head screws are present for mounting.
Construction Details
Mass-produced die-casting with a hollow flange; surface-mounted using standard hardware (industrial machining).
Functional Features
Flush mounting flange with screw holes; concentric texture for grip or impact distribution; designed for wall protection.
Handle & Grip Details
Fixed knob-style protrusion; no separate handle or ergonomic grip intended for manual manipulation.
Craftsmanship Details
Machine-cast industrial quality; visible seam lines and functional rather than artistic finishing.
Authentication Indicators
The presence of modern steel Phillips-head screws and the specific pattern of white, flaky corrosion (pitting) confirm this is not silver.
Origin & Manufacturing
Likely manufactured in China or a similar industrial hub for global facility maintenance supply.
Era & Period
Modern / Industrial (Late 20th - Early 21st Century)
Age Estimate
Circa 1990-present day; condition suggests 5-10 years of use in a high-moisture or chemical environment.
Cultural Significance
Represents the standardization of 20th-century institutional architecture and facility management.
Condition Notes
Poor. Significant surface oxidation, pitting, and possible plating failure. The metal is 'blooming' with white corrosion typical of non-noble alloys.
Value Estimate
Nominal trade value ($5 - $15 USD new); negligible as an antique or collectible.
Care & Maintenance
Clean with mild detergent; if oxidation is heavy, replacement is usually more cost-effective than restoration.
Similar Pieces
Commercial door stops, elevator buttons, or wall-mounted coat hooks of industrial grade.
Interesting Facts
Items like this are designed for durability over aesthetics, yet the corrosion pattern indicates it has been exposed to harsh cleaning chemicals.
