Outdoor Bronze Plaques

An outdoor plaque has to survive sun, rain, frost, sprinklers, mowers and the hands that touch it, and still be readable in fifty years. Cast bronze is the one plaque material that does this without a coating to fade or a film to peel, which is why cemeteries, park departments, universities and historical societies across the USA specify it for anything that must stay outdoors. Our outdoor bronze plaques are cast in solid bronze with raised lettering, in any size from 8 by 2 3/8 inches up to 22 by 15 3/4 inches, with the fastening to suit stone, brick, concrete, wood or a post. You design the plaque online, see its price as you work, and approve a free proof before casting.

Why cast bronze is the outdoor plaque material

Bronze is an alloy of copper and tin that does not rust. When it is exposed to weather it forms a thin, stable oxide layer, the patina, that protects the metal beneath; it does not flake like paint or pit like steel. The lettering on a cast plaque is part of the casting itself, standing about a tenth of an inch proud of the background, so there is nothing printed, engraved or filled that can wear away. Cast bronze plaques from the 1800s are still legible on buildings and battlefields across the country. Aluminum plaques depend on a painted or anodized finish that chalks and fades in five to fifteen years, and stainless steel plaques carry etched or printed lettering that reflects the sky and disappears in bright light. Our post on bronze vs aluminum and stainless steel compares the three in detail, and how long bronze plaques last covers the evidence.

Where outdoor bronze plaques are used

• Memorial gardens and backyards: on a boulder, a garden wall, a bench or a stake beside a planting. See memorial garden plaques.
• Cemeteries: flat grave markers on a granite base, plates added to headstones, niche and crypt fronts. See bronze grave markers.
• Parks and trails: bench, tree and trailhead plaques under city and county memorial programs, which almost always specify cast bronze. See memorial bench plaques and memorial tree plaques.
• Buildings: dedication and cornerstone plaques, architect’s plates, address plaques and entrance signs on brick, stone, concrete and render. See building dedication plaques and bronze house number plaques.
• Historic sites: wall and post mounted markers for historic homes, districts and events. See bronze historical markers.
• Pets: garden and lawn plaques for a dog or cat. See outdoor pet memorial plaques.

How an outdoor plaque looks over time

A new cast bronze plaque has bright polished letters on a darkened, textured background in a warm golden brown. Over the first years outdoors the background deepens to chocolate brown, and in damp or coastal air green highlights can appear, the same patina seen on statues. The letters, polished by rain and by hands, stay the brightest part, so the contrast that makes the plaque readable actually improves with age. If you prefer the as new look, a clear lacquer or a paste wax applied every year or two slows the patina. Most families and institutions let the plaque age naturally; our guide to cleaning a bronze plaque explains the wash and wax routine, which takes ten minutes a year.

Fastening to stone, brick, concrete, wood and posts

The designer offers three fastenings, and the surface decides which to pick:

• Stone, boulders, brick and concrete: lugs with studs. Two or four threaded studs on the back of the plaque are set into drilled holes with epoxy or hydraulic cement, so the face shows only the lettering and the plaque cannot be lifted. For a rough boulder, choose a plaque small enough to sit on a flat face, or have a mason dress a pad for it.
• Granite bases and polished stone where drilling is not allowed: flat back, bonded with a structural adhesive rated for exterior use.
• Timber benches, fences, gates and signboards: screws visible from the front through cast holes at the corners, using stainless screws so there is no rust staining.
• Posts and stakes: a plaque with screws or studs is fixed to a timber or metal post set in concrete below the frost line, or to a ground stake angled to read from the path, with the top edge kept below mower height or inside a mulch ring.

Our step by step installation guide covers each surface with the tools and adhesives to use.

Sizes and prices

Outdoor plaques range from a one line name plate to a historical marker paragraph. These are the sizes ordered most often and the price each gives in our designer for a standard rectangle with a classic border and leatherette background, shipping included. Any size between them can be typed in, up to the designer’s maximum of 22 1/16 by 15 3/4 inches; larger plaques are quoted on request.

Outdoor lettering should be at least a quarter of an inch tall, and larger where the plaque is read from a path several feet away. A quarter inch letter gives about three to four characters per inch of width; the designer shows your wording at true scale so you can judge the fit before you buy. See bronze plaque sizes for the characters per size guide and bronze plaque prices for the full table.

Designing for the outdoors

A few choices make an outdoor plaque easier to read and longer lasting. Keep the words few and the letters large; a plaque read from a path needs fewer, bigger words than one read at arm’s length. Pick a border, because the raised rim protects the background and gives the eye a frame. Choose a textured background rather than a smooth one, as it hides water marks and keeps the contrast with the polished letters. Emblems, motifs and borders are cast in relief and weather exactly as the letters do; a photograph is added as a ceramic insert or an image fused into the bronze, both made for outdoor use, as explained on bronze plaques with photo. Ovals and circles are available as well as rectangles, and a portrait rectangle suits a stake or a narrow post.

How to order

1. Open the free design tool, pick the shape and set the size in inches. The price updates as you go.
2. Add the wording, choose a border and background, and add an emblem, motif or photo if you want one.
3. Pick the fastening: flat back, concealed lugs with studs, or screws visible from the front.
4. Save the design and order it from My Account. We send a written proof, and nothing is cast until you approve it.

Frequently asked questions

What is the best material for an outdoor plaque?

Cast bronze. It does not rust, its raised letters are part of the casting and cannot fade or peel, and it lasts for generations with an occasional wash. Aluminum depends on a coating that fades within five to fifteen years, and stainless steel lettering is etched or printed and hard to read in sunlight.

Does bronze rust outside?

No. Bronze forms a thin protective patina that darkens the background to brown and, in damp climates, may show green highlights over many years. The metal beneath is unaffected and the polished letters stay bright.

How much does an outdoor bronze plaque cost?

In our designer a 6 by 4 inch garden plaque is $382.98, an 8 by 6 is $540.98, a 12 by 8 is $796.86 and a 16 by 12 is $1,264.58, shipping included. The price updates on screen as you change the size, border, background, emblems and fastening.

How do I fix a bronze plaque to a rock or a wall?

Choose lugs with studs in the designer, drill matching holes in the stone or brick, set the studs in epoxy or hydraulic cement and press the plaque home. Where drilling is not allowed, choose a flat back and bond it with an exterior structural adhesive. Timber takes screws through the front.

How long does an outdoor plaque take?

Allow about 3 to 4 weeks for casting after you approve the free proof, plus 5 to 10 days for delivery anywhere in the USA and worldwide.
