Copper in Architecture

Copper allows the creation of forms that work that work with the elements to become more beautiful with time. Copper surfaces age gracefully, rather than "corrode" as many other metals do. Copper is easy to work with and very forgiving as a cladding material, which translates into successful outcomes for all parties involved in the building process.

Copper's Antimicrobial Properties

Copper is also recommended for the use in "touch surfaces" for public areas because of it's extreme antimicrobial properties. This ability is being advanced by the industry as a credible way to combat "superbug" outbreaks in hospitals.

Grades of Copper Available
DHP Copper (Phosphorous De-oxidised Non-arsenical Copper)

Commonly used for architectural features, such as roofing, cladding, and rainwater goods due to it's excellent roll forming capabilities. Phosphorous De-oxidation enables brazing and welding operations to be employed without Hydrogen embrittlement occurring in the joined area. This process lowers the electrical conductivity of the Copper from 101% IACS to approximately 85% IACS.

ETP Copper (Electrolytic Tough Pitch Copper)

Noted for it's high electrical and thermal conductivity, good corrosion resistance and solderability. In New Zealand it is generally used in applications where it's high electrical conductivity 101% IACS is required.
