From surgical-grade stainless to aerospace aluminum and architectural brass, Burnish 354 delivers repeatable, measurable surface finishes — Ra values documented, tolerances held, timelines kept.
Six integrated service lines, run on the same documentation, tooling and quality controls. Send us a print, a sample or a Ra target — we will return a finished part, a measurement report and a paper trail.
Achieves #8 architectural mirror and optical-grade super-mirror (Ra < 0.01 µm) on stainless, aluminum, copper and titanium. Used in pharmaceutical, semiconductor and luxury architectural installations.
View service details4×10 ft capacity for architectural cladding, elevator panels and equipment enclosures. Grain direction is controlled, consistent panel to panel, and verified against approved reference samples.
View service detailsPost-machining finishing for precision components — deburring, edge-break, cosmetic and functional surfaces. We accept parts in batches from 5 to 5,000 with consistent Ra values across the entire run.
View service detailsASTM A967 and ASTM B912 compliant passivation and electropolishing for medical, food-grade and marine stainless. Free iron testing, salt-spray documentation and full lot traceability included.
View service detailsOn-site and in-shop restoration for architectural metal, vintage automotive, marine hardware and damaged production parts. Weld-blend, scratch removal, pitting repair and full re-passivation available.
View service detailsOne-off and small-run fabrication with finishing built in — elevator cabs, handrails, signage substrates, custom fixtures. Drawings reviewed for finishability before cutting starts; sample panels available.
View service detailsMost polish shops sell a look. We sell a measurement. Every job leaves our floor with documented surface roughness, a photographic record and the parameters used to get there — so the next run is identical.
Every critical surface is measured on a calibrated Zeiss or Mahr profilometer. Reports are issued in PDF with operator, instrument, calibration date and per-zone readings.
Abrasive sequences, wheel speeds, contact pressures and dwell times are codified per material. New operators are trained to the document, not the person next to them.
304 behaves nothing like 316L. 6061-T6 nothing like 7075. We select media, compounds and tooling per alloy, hardness and prior cold-work — not by guessing at the buffer.
Heat numbers, passivation batch IDs, inspection records and operator sign-offs are retained for seven years. Auditor-friendly packs available on request for regulated industries.
From RFQ to crating, you see the same milestones our floor team uses. Most milestones are timestamped and available to you in your customer portal.
We review the drawing, material cert and any finish callouts. If the spec is ambiguous or unachievable, we flag it before tooling touches the part.
On first-run projects, a 6×6 reference panel is produced and shipped for written approval. Production parameters are locked to the approved sample.
Sequenced grinding, pre-polish, color buff and final mirror/passivation per the locked routing. In-process checks at every stage transition.
Profilometer readings, visual comparison to the reference panel, photographic record and full traceability pack. NCRs are written, not buried.
VCI film, foam separators and ISPM-15 crating for export. Released with a signed CofC and digital inspection report — same day, every time.
A few excerpts from the production and quality leads we work with week in, week out. Full references available under NDA.
We send Burnish 354 lots of 600 pharmaceutical-grade fittings per batch. Their Ra certs are clean, their packaging is undamaged on arrival, and the finish is the same on part one and part six hundred. That is rare in this industry.
The architectural firm we work with specified a custom non-directional satin on 220 elevator panels. Burnish 354 produced a reference, matched it on every panel, and their foreman caught a mill-damage issue on incoming stock we would have shipped anyway.
Restoration work is the worst job in any shop — inconsistent, undocumented, prone to scope creep. Burnish 354 took a basket-case vintage brass railing, brought it back, and gave us a finish map I could hand to the historical society without editing it.
Our portfolio covers architectural mirror installations, pharmaceutical fittings, marine hardware and one-off custom work. Photographed in our inspection booth under controlled lighting — so the finish you see is the finish you receive.
