Material Replication Coatings
Natural material aesthetics. Aluminum performance.
The Materials Architects Want. The Performance They Need.
Architects increasingly specify natural material aesthetics — terra cotta, Corten steel, exposed concrete — but the real materials come with weight, maintenance, inconsistency, and cost tradeoffs that can complicate a project.
Spectrum applies advanced coating systems to aluminum substrates that replicate the visual character of these materials with none of their limitations. The result is lightweight, corrosion-resistant aluminum that looks like the natural material the architect specified, backed by up to 20-year warranties and full AAMA 2605 compliance.
Each material replication finish uses multi-coat application techniques tailored to the specific material being replicated — from the warm mottled patina of Corten steel to the raw texture of poured concrete to the warm earth tones of terra cotta clay.
Material Replication Finishes
Three distinct coating systems, each engineered to replicate a specific natural material.
Terra Cotta Coatings
Warm, earth-toned finishes that replicate traditional terra cotta clay tile — ideal for facades, sunshades, and accent elements.

Why Replicate?
The case for coated aluminum over the original materials.
The value proposition is simple: architects get the look they want without the material compromises they don't. Coated aluminum is a fraction of the weight of concrete or clay, doesn't stain adjacent surfaces like real Corten, and delivers consistent color and texture from the first piece to the last — something natural materials can't guarantee between production runs.
Every material replication finish goes through Spectrum's full 7-stage pretreatment process and carries the same performance warranties as standard architectural coatings.
