Outdoor Dimensional Letters — Outdoor Sign Specs | SOC
Outdoor Dimensional Letters
Cast, fabricated, and formed letters built for exterior exposure.
Dimensional letters and logos bring architectural depth to commercial exteriors. Material, finish, mounting hardware, letter height and exposure should be selected around the building and its ongoing maintenance conditions.
Durability Specifications
How Outdoor Dimensional Letters Perform Outdoors
UV Protection
Cast metals develop natural patina or are clear-coated. Powder-coated aluminum rated 10–15 years. Stainless steel requires no coating.
Fade Resistance
Metal letters do not fade. Painted finishes use PVDF or 2-part polyurethane. Clear-coated bronze and brass maintain appearance for decades.
Weather Sealing
Stud-mounted letters with silicone caulk at wall penetrations. Cast metals are solid — no water intrusion paths. Weep holes in hollow fabricated letters.
Wind Load Rating
Individual letter stud mounts engineered per letter size and weight. Large letters use multiple studs with structural epoxy. Rated 130+ mph.
Corrosion Resistance
Stainless steel and cast bronze are inherently corrosion-resistant. Aluminum letters use anodized or powder-coated finishes for coastal environments.
Longevity
Cast bronze and aluminum letters routinely last 30–50 years. Fabricated stainless steel letters are essentially permanent with minimal maintenance.
