Class I Mil Tolerance
Minimum anodic coating thickness for Class I architectural finishes per AAMA 611. Average coating across the part exceeds 0.8 mil in standard production.
- Class I: 0.7 mil minimum (18 μm)
- Class II: 0.4 mil minimum (10 μm)
- Average run: 0.82–0.95 mil
- Measured at 5 points per part
- Certificate of Conformance included
Salt Spray Endurance
Continuous salt fog exposure per ASTM B117 with no base metal corrosion. Exceeds AAMA 611 Class I requirement of 3,000 hours.
- 3,000 hr exposure — zero base metal corrosion
- Scribe creep: ≤ 1/16″ from scribe line
- Independent lab certification available
- Annual re-certification on file
- Coastal / marine project proven
Delta-E Batch Match
Color consistency measured with spectrophotometer across all parts in a batch. Critical for multi-floor curtain wall jobs where panels must match across deliveries.
- ΔE ≤ 0.5 within single batch
- ΔE ≤ 1.0 batch-to-batch (same alloy)
- Master standard retained 24 months
- Color match approval before full run
- 12 standard architectural colors in stock
Max Extrusion Length
Tank dimensions accommodate full-length curtain wall mullions and storefront frames without splicing. Accepts standard 24-ft and 26-ft extrusion lengths.
- Tank length: 28 ft (interior)
- Max part width: 36 inches
- Max rack weight: 2,400 lbs
- Custom fixturing for complex profiles
- Sunshade louvers & deep-pocket frames accepted
Weekly Throughput
Sustained production capacity across two active lines. Construction-scale jobs from 500 to 50,000 sq ft accommodated with dedicated scheduling.
- 2 active anodizing lines
- Dedicated scheduling for jobs > 5,000 sq ft
- Rush processing available (+ 15%)
- JIT delivery coordination available
- Partial shipments on phased projects
Hot DI Seal Standard
Hot deionized water seal closes the anodic pore structure, locking in color and maximizing corrosion resistance. Nickel-acetate mid-seal available on request.
- Hot DI water: 200–212°F, 30 min minimum
- Nickel-acetate mid-seal available
- Seal quality: ASTM B136 dye stain test
- Conductivity: < 10 μS/cm seal water
- Seal verification on every batch
From Mill Finish to
Oxide-Clad Profile
Four process phases. Every parameter logged. Every batch certified. The kind of process control that holds up in a submittal review.
Incoming Inspection & Alloy Verification
Every rack of extrusions is verified against shop drawings before racking. Alloy grade, temper, and surface condition are logged. 6063-T5 and 6061-T6 are our primary alloys — we flag anything that will affect coating adhesion before it touches chemistry.
- 6063-T5 / 6061-T6 primary alloys
- Surface defect documentation
- Dimensional check vs. shop drawings
- Alloy spark test on unknowns
Pre-Treatment: Etch, Desmut, Clean
Parts cycle through alkaline etch, nitric desmut, and DI rinse before any current is applied. The etch tank removes the natural oxide layer and machining oils — a consistent starting surface is the only way to get a consistent finish. We run 3-minute dips at 140°F.
- Alkaline etch: 140°F, 3 min
- Nitric acid desmut
- DI rinse: < 10 μS/cm
- Visual inspection before anodize
Anodize: Sulfuric Acid Bath
Parts are racked and lowered into our 18% sulfuric acid bath at 68–72°F. Current density is held at 12 ASF with a programmable rectifier — the same parameters every run. Class I requires 60 minutes at these conditions to build 0.7 mil of anodic oxide. Our rectifier data is logged per batch.
- 18% H₂SO₄ at 68–72°F
- 12 ASF current density
- 60-min run for Class I
- Rectifier data logged per batch
Color & Seal
Clear anodize goes directly to hot DI water seal. Colored finishes go through electrolytic coloring (tin sulfate) or organic dye immersion before sealing. Our hot seal tank runs at 200°F — every part gets 30 minutes minimum. Seal quality is verified with ASTM B136 dye stain.
- Electrolytic coloring (tin sulfate)
- Organic dye: 12 standard colors
- Hot DI seal: 200°F, 30 min min.
- ASTM B136 dye stain verification
