Frequently Asked Questions
COR-TEN steel letters are ideal for exterior signage where a bold, industrial, or rustic aesthetic is desired. They're commonly used on building facades, monuments, public parks, landscape architecture, and interior feature walls for a unique look.
COR-TEN is a weathering steel that forms a protective rust-like patina when exposed to moisture and air. This natural layer prevents further corrosion, making it a durable material for outdoor signage without the need for paint or coating.
COR-TEN steel letters arrive as raw, unsealed steel and gradually develop a deep orange-brown patina over several months. The aging process creates a distinctive, evolving appearance that blends naturally into many environments.
We offer COR-TEN letters in sizes from 4″ to 36″ tall and thicknesses ranging from ¼″ to 1″. We’ll help recommend the right dimensions based on your design, wall space, and mounting method.
COR-TEN letters are usually stud-mounted directly into masonry or wood surfaces. Spacers can be added for a floating effect. All mounting hardware and an installation template are included with your order. Nationwide installation is also available.
Yes. We can waterjet-cut COR-TEN steel into standard fonts or fully custom letterforms and logos. Our team will help adapt your design and ensure it suits the material's properties and your installation site.
During the patina development phase, COR-TEN steel may release rust runoff, which can stain nearby surfaces. We recommend careful placement and sealing light-colored or porous walls to minimize potential staining.
We typically ship COR-TEN letters as raw steel so they can weather naturally in place. If you prefer a pre-weathered look, you can accelerate the process by spraying the letters with water before installation. Sealing is not recommended, as it stops natural patina formation.
After receiving your deposit, we’ll send a detailed digital layout showing font, size, spacing, and mounting. You can request up to two revisions. Once approved, we begin production and ship your letters with all hardware and instructions.
