Commercially pure copper screening is resistant to atmospheric corrosion, salt air and brine.

In many situations, copper will slowly darken with time. Screens exposed to salt sprays often turn green although the copper holds up extremely well in costal applications.

Copper was the earliest popular material used for insect and fly screens.  Historic structures are typically screened with copper.

When possible, bronze should be considered when replacing copper as it performs equally well with salt spray and is more durable than pure copper.

Features:

Copper offers excellent electrical and thermal conductivity. It is non-magnetic, anti-sparking and is resistant to atmospheric corrosion, salt air and brine. Copper applications are limited due to its low tensile strength, and poor resistance to abrasion and common acids.
