Copper Post Caps

Copper Post Caps
Make your own copper post caps!

This is a popular treatment for many who live along the coast. Wood exposed to the elements may rot, but with a custom made copper cap- the pier post looks beautiful and is protected from the salt water and harsh environmental conditions.

The same treatment can be modified to protect fence caps, decking, wooden garden structures, or any other wood that is exposed to the elements.

In creating copper post caps, people will use 10 MIL, 16 MIL, 22 Mil/16 Ounce copper sheet, with 10 MIL (30 gauge)being the most popular thickness. It is very pliable and easy to work with, but will hold up well over time. Still, some people prefer a thicker material. To help decide which you might prefer, see our copper sheet thickness guide for a video description of the various thicknesses.

The pictures below are from a new marina at a resort in Abaco, Bahamas. They made over 1,100 copper piling caps for the piles using our 10 MIL copper sheet. In a salt water environment, the unsealed copper quickly begins to develop the beautiful turquoise patina you see in the pictures below.
