Modular Corten Steel Mailbox

A modular corten steel mailbox designed to be mixed, matched, and customised to suit your home, farm, or entranceway.

Finish & Care

Corten steel is supplied raw and will naturally develop a protective rust patina over time when exposed to the elements. This is normal and part of the material’s character. Stainless steel components will remain silver.
