(773) 277-1600 | Architectural metalwork makes a statement that lasts for decades. From the stainless steel cladding of landmark skyscrapers to the precision hardware of luxury interior spaces, the surface finish of metal components defines the visual character and long-term durability of the built environment.
Able Electropolishing works with architects, fabricators, and contractors on building facade cladding, structural hardware, decorative metalwork, handrails and balustrades, signage, and precision architectural hardware. Electropolishing delivers the bright, reflective, chrome-like finish that distinguishes premium architectural metalwork while simultaneously providing the corrosion resistance to maintain that appearance for the lifetime of the building.
Electropolishing does not just improve appearance — it removes micro-burrs and surface contaminants that cause tea staining and rust bleeding on stainless steel architectural elements, and creates a dense Cr₂O₃ passive layer that resists the atmospheric, urban, and coastal environments that building exteriors face every day.
Send us your architectural component sample to electropolish free and see the difference in finish quality and corrosion resistance before committing to production quantities.
Electropolishing delivers dramatically different—and dramatically better—finishes depending on the alloy. Here is what to expect from Able’s process.
Excellent chrome-like bright finish. The architectural standard: brilliant, highly reflective surface that resists tea staining, rust bleed, and urban atmospheric corrosion.
Outstanding reflective finish. Bright warm-toned reflective surface. Ideal for decorative aluminum cladding and interior architectural elements.
Outstanding finish — the best in the brass family. Rich golden tone with high luster. Perfect for decorative hardware, signage, and luxury interior architectural elements.
Excellent finish on copper. Bright warm reddish-orange tone with high reflectivity. Ideal for decorative copper cladding, roofing accents, and contemporary architectural features.
Electropolishing produces a chrome-like bright finish on stainless steel that no mechanical polishing method can match for uniformity and reflectivity. The finish is consistent across complex geometries — edges, curves, and recesses all finish uniformly, which mechanical polishing cannot achieve.
The most common complaint about architectural stainless steel — tea staining and rust bleeding — is caused by free iron and embedded contaminants left by mechanical finishing. Electropolishing removes free iron completely and creates a dense Cr₂O₃ layer that prevents oxidation, eliminating rust staining on building facades permanently.
Building facades face acid rain, industrial pollution, coastal salt spray, and urban grime. Electropolishing’s passive oxide layer dramatically resists atmospheric corrosion, maintaining the appearance of architectural metalwork through decades of urban and coastal exposure without polishing or maintenance.
Rough mechanically polished surfaces trap fingerprints, grease, and urban particulates in surface scratches. Electropolishing’s ultra-smooth surface releases soiling with minimal effort — critical for interior architectural hardware and high-touch public surfaces.
Mechanical polishing leaves lap marks, directional scratches, and uneven finishes on complex architectural shapes. Electropolishing finishes uniformly across all surfaces — inside corners, recesses, tubes, and complex profiles all achieve the same consistent surface quality.
Architectural metalwork must maintain its appearance for 50 to 100 years. Electropolishing creates a passive layer that is self-healing — when scratched, the Cr₂O₃ layer reforms in the presence of oxygen, continuously protecting the surface throughout the building’s lifetime.
Urban atmospheric pollution — SO₂, NOₓ, and acid rain — attacks unprotected metal surfaces continuously. Electropolishing’s passive layer dramatically resists acidic atmospheric attack.
Coastal buildings within miles of the ocean face relentless chloride salt spray that causes pitting and tea staining on standard stainless. Electropolishing’s elevated Cr:Fe ratio prevents this.
Interior architectural hardware is touched thousands of times daily. Rough mechanical finishes show every fingerprint — electropolishing’s smooth passive surface releases oils and grease easily.
Building facade metals expand and contract with seasonal temperature changes. Electropolishing’s uniform passive layer maintains integrity through decades of thermal cycling without delamination or cracking.
Electropolishing exceeds ASTM passivation standards, providing dramatically better corrosion resistance than chemical passivation alone, while delivering the superior aesthetic finish architects specify.
Able provides full documentation of surface finish Ra values and passivation quality to support architectural specifications and project documentation for commercial construction.
We work with architects and fabricators to match specific Ra targets, develop custom finish specifications, and provide sample coupons for design approval before production quantities.
Stainless steel and aluminum facade panels electropolished for consistent bright finish across panel sets, with uniform corrosion resistance for the life of the building.
Interior and exterior handrail systems, balustrades, and guardrails electropolished for superior corrosion resistance, cleanability, and a premium aesthetic finish that lasts without maintenance.
Stainless steel and brass building signage, plaques, and dimensional letters electropolished for brilliant finish, sharp edge definition, and permanent corrosion resistance in interior and exterior environments.
Push plates, pull handles, hinges, and threshold hardware electropolished for consistent premium finish, fingerprint resistance, and durability in high-traffic commercial entrance systems.
Exposed structural connectors, bolts, and tension rod fittings electropolished for uniform finish and corrosion resistance on architectural structural systems where hardware is a design element.
Perforated stainless steel screens, decorative grilles, and mesh panels electropolished to remove punch burrs, provide uniform finish across all surfaces, and resist atmospheric corrosion.
Stainless steel roofing fasteners, flashings, and waterproofing hardware electropolished for maximum atmospheric and UV corrosion resistance — critical for long-term weather-tight performance.
Learn why enhanced corrosion resistance is one of the most common reasons architects and fabricators rely on electropolishing — including case studies showing the difference electropolishing makes versus passivation alone on architectural stainless steel.
Perforated screens, decorative grilles, and machined architectural hardware demand burr-free surfaces. Learn why electropolishing is more effective than mechanical deburring for precision architectural components.

Metal fabrication for parts used in the medical and electronics industries can involve dimensions as small as a grain of rice — or even a strand of hair. At that scale, surface defects may be invisible to the naked eye,…
While stainless steel is known for its corrosion resistance, it contains iron, which is susceptible to corrosion, especially if parts are frequently exposed to moisture or harsh environments. Contamination left behind by machining processes can also impede the corrosion resistance…
Electropolishing is a highly controlled electrochemical process that directly impacts surface integrity, corrosion resistance, cleanliness, and performance.
