Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits

Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

Post-consumer aluminum building material scrap; residential/commercial siding and gutter systems; painted architectural aluminum; building demolition/renovation source; paint removal processing required; significant hazmat risk (lead paint, VOCs); established building waste recycling stream

Acceptable Inclusions

Paint coating 5-15% (defining characteristic)
Acrylic, polyester, vinyl, enamel paint types
Paint adhesion varying (thick or thin acceptable)
Light oxidation (hidden under paint)
Weathering from outdoor exposure

Prohibited Materials

Aluminum <90% core (insufficient metal content)
Lead-based paint >5% (hazmat; pre-treatment verification)
Asbestos in older coatings (pre-1980s risk)
PCB-containing paint
Ferrous/stainless steel contamination
Unknown paint composition or age
Friable paint or contamination hazard

Quality Assurance

Testing protocols, sampling methods, and acceptance criteria.

Sampling Protocol

Required Test Methods

Visual Inspection

Method 1

Purpose

Confirm aluminum siding (not ferrous)
assess paint condition
detect hazmat indicators

Acceptance Criteria

Aluminum siding apparent
paint coating visible
no ferrous contamination
building era/color identifiable

Procedure

100% visual of all samples
verify aluminum appearance
assess paint color/condition
identify siding type
note any obvious hazard indicators

Magnetic Test

Method 2

Purpose

Exclude ferrous/stainless contamination
verify aluminum non-magnetic

Acceptance Criteria

Non-magnetic (aluminum expected)
no strong ferrous attraction

Procedure

Magnet test on sample siding pieces
no ferrous response expected

Building Age & Era Assessment

CRITICAL

Method 3

Purpose

determine building construction period
assess lead paint probability

Acceptance Criteria

Building era documented
pre-1978 = presumed lead risk
post-1978 = lead-free assumption

Procedure

Historical building assessment if available (address research)
visual era indicators
document construction period

Lead Paint Screening

CRITICAL

Method 4

Purpose

detect lead-based paint presence
trigger hazmat protocol if positive

Acceptance Criteria

Lead-free confirmed OR lead content assessed and documented

Asbestos Risk Assessment

CRITICAL

Method 5

Purpose

identify asbestos risk in older paint coatings

Acceptance Criteria

Asbestos-free confirmed OR risk assessment documented
no friable asbestos

Procedure

Visual inspection for friable/powdery coating (asbestos indicator)
pre-1980 materials flagged for potential asbestos

Paint Type Identification

Method 6

Purpose

Identify paint type (acrylic, polyester, enamel)
assess removal difficulty
determine processing requirements

Acceptance Criteria

Paint type identified
removal method compatibility determined

Procedure

Visual assessment of paint finish
adhesion test (scratch test)
paint type classification

Paint Coating Weight Analysis

Method 7

Purpose

Verify paint coating 5-15% by weight
assess processing loss expectations

Acceptance Criteria

Paint 5-15% by weight confirmed
within expected range

XRF Spectrometry

Method 8

Purpose

Analyze painted surface
detect lead in paint
identify paint contaminants (hazmat assessment)

Acceptance Criteria

Lead status determined (present/absent)
aluminum base confirmed after paint consideration

Procedure

Surface XRF identifies paint elements including lead
establishes hazmat status
hazmat protocol triggers if positive
