Metal Plaques

Overview of Metal Plaques

Fig. 1 - This picture shows the wide variety of styles of our dimensional metal wall plaques for Federal and State governments, courts , police, universities and clubs. Some plaques are carved in 3-D bas-relief, others in 2.5-D relief. Shown are bronze, brass, nickel-silver & aluminum -plated, and 24K gold-leaf and silver-leaf gilded plaques.

 

WELCOME TO OUR METAL PLAQUE  SECTION  (STYLE CATEGORY 1.2)      Welcome to our section  describing our metal plaques, where we show over 200 examples of various types of metal plaques in seven photo galleries. This section describes only our metal plaques; our painted plaques are described in our Painted Plaques section, and our natural and stained wood plaques are described in our Wood Plaques section.  We design and fabricate thousands of  elegant and professional custom 3-D and 2.5-D metal plaques each year for courts, government organizations, the military units, police & sheriffs, universities, clubs, corporations, and  homes.  Each  plaque is custom crafted  by our experienced and skilled craftsmen and artisans.  We use  several different techniques to make these impressive and authentic plaques which  retain their dignified beauty over many decades. These plaques are non-fading, moisture-proof,  graffiti-resistant and long-lasting.

This section, along with the  7 photo Gallery pages listed above horizontally under the gold masthead above, describes and shows hundreds of  examples of these metal  plaques. We offer  seven styles of custom metal plaques, each with different prices:

(1) Bronze-Plated (Style Categories 1.2.1 & 1.2.2, and Price Codes MA1 & MA2) 

(2) Brass-Plated (Style Categories 1.2.3 & 1.2.4, and Price Codes MB1 & MB2) 

 (3) Copper-Plated (Style Categories 1.2.5 & 1.2.6, and price code MC1 & MC2) 

(4) Nickel-Silver and Aluminum-Plated (Style Categories 1.2.7 & 1.2.8, and Price Codes MD1 & MD2) 

(5) 24K Gold-Leaf Gilded (Style Categories 1.2.9, 1.2.10., 1.2.11, & 1.2.12 and Price Codes ME1 & ME2) 

(6)  Pure Silver-Leaf Gilded (Style Categories 1.2.13, 1.2.14, & 1.2.15,  and Price Codes MF1, MF2, & MF3)

(7) Solid Cast Bronze & Aluminum (Style Category 1.2.16, 1.2.17, 1.2.18, & 1.2.19 and Price Codes MG1, MG2, MG3 &  MG4).

The prices for each of these different styles for various size plaques is given on the PRICE  webpage (click here or on PRICE in gold masthead at top of this page) . These plaque types are listed by Style Category and Price Code and several plaque sizes. 3-D plaques have higher prices than 2.5-D plaques because of the additional labor and time to carve, plate and polish them. Cast solid metal plaques, especially custom 3-D plaques,  have the highest prices , with gold and silver-leaf  gilded plaques having  lower prices. Metal-plated brass plaques have the lowest prices of our real metal plaques; however, our metallic painted faux-metal plaques (see paragraph below) have even lower prices, These are described in our 3-D Painted Plaques and 2.5-D Painted Plaques sections.  Fig. 1 above and Fig. 2 below show examples of these different styles of metal plaques.

Fig. 2 - The picture above shows examples of bronze, brass, copper, and nickel-silver plated plaques.

We have another option for clients who want  metal-looking plaques but who do not want the expense of real metal plating.  We can paint our 3-D and 2.5-D carved plaques with Matthews or 1-Shot gold, silver, bronze or brass metallic paint, which providesd the colors of real metals but not the shine and reflections that only real metals can give. These plaques are only about 80% of the price of our metal-coated plaques, and many clients select these, including the US Tax Court, for which we made 18 plaques,  and the Superior Court of California in Los Angeles,  for which we made 24 plaques. For examples and photos of these metallic painted plaques, please visit our gallery Two-Color Painted Plaques page.

You are always welcome to call Christie or Regina at 951-698-8484 to discuss these various options or you can email us at info@artsignworks.com to get more information, to describe or discuss a plaque you want made, or to get  prices.

DESCRIPTION OF DIFFERENT METAL PLAQUE STYLE FABRICATION TECHNIQUES

We make most of our metal plaques & signs by first carving ultra High-Density-Urethane HDU (density of 20 lb/ft3) in either 3-D bas-relief or 2.5-D flat relief (for all techniques except except for solid bronze or aluminum cast plaques). We  have five different  methods to fabricate a metal plaque or sign, one for each style,  which are described below. 

METAL PLATING. We spray on a coat about 1/60th of an inch (10 to 15 mils thick)  real metal particles (you have a choice of bronze, brass, copper, nickel-silver/German silver, stainless steel, or aluminum) imbedded in a binder over the entire plaque. We may then  optionally paint  a dark patina or dark paint (usually dark brown or black)  on the background to enhance contrast, and then polish and burnish the metal plating first by machine and then by hand, to make some areas shiny. This technique is available for both 3-D and 2.5-D plaques.

Our metal-plated plaques and signs have  advantages over molten metal cast bronze or brass (solid) metal plaques, because they cost about 1/3  as much and weigh about 1/5 to 1/10 as much. These metal-plated  HDU plaques have the same appearance as cast bronze, brass, copper or aluminum, and they will last 30 years or more, for both exterior and interior applications, if people do not walk on them or rub them.  They are completely waterproof and the metal gives a hard metal veneer over the HDU substrate The HDU substrate itself about the same density as  Cedar or Redwood (20 lb/ft3).  The metal veneer is about 12 mils thick (1 mil = 0.001 inch), 10 times thicker than electro-plating, and forms a very hard, protective, weather and UV resistant shell.  All our metal-coated products are polished first by a buffing machine and then by hand with a buffing cloth to a high luster. This takes our craftsmen many hours.

The metal-plated background areas can be covered with either a patina to provide contrast and give the effect of age, or they can be painted. The patina is not perfectly uniform (it has very light non-uniformities in shade, i.e., slight blotchiness), because of the difference in chemical bonding, temperature, etc. to the metal surface. Every plaque will look slightly different. This minor unevenness gives it a very authentic, antique look. We can also paint the metal backgrounds with a flat or satin black or dark gray paint to give a very even, new look that provides a higher  contrast between the background and text & artwork than patina does. Any of our metal-coated plaques can have either a patina or painted background. After the bright metal surface is polished and the background patina or paint is applied, we can coat the plaques with either a satin or gloss clear coat. The gloss is shiny and reflects light specularly whereas the satin finish will reflect  light diffusely. 

Four examples of metal-plated plaques (bronze, brass, copper, and nickel-silver) are shown above in Fig. 2. Fig 3 below shows the finish quality for four of the metals, when the plated HDU samples are polished and buffed. Each metal is described below, along with its heritage. You can click on the gold underlined text to go to the photo Gallery page for that metal, or click on an item in the horizontal list below the gold masthead to see that Gallery page.

Fig. 3 - The picture above shows samples of brass, bronze, aluminum and copper-plated plaque finishes. They are all polished.

Bronze. We make many plaques using bronze as the plating metal. Bronze is an alloy consisting primarily of copper,  with about 12% tin and small amounts of other metals such as aluminium, manganese, nickel or zinc.  The archelogical period where bronze was the hardest metal in widespread use is known as the Bronze Age, which began  in Western Eurasia began about 4000 BC., Bronze was used extensively in Europe and China in ancient times for weapons, armor and tools, but it was eventually  replaced in most applications by iron around 1300 B.C, ushering the Iron Age.   Bronze is commonly used today for statues, plaques, jewelry, and other decorative items.  Durable and classically beautiful, Bronze possesses all the physical properties of solid cast bronze yet its composite matrix gives it the added benefit of being anti-corrosive.

Brass. Brass is the most popular metal for plating our plaques, probably because it is bright and shiny and has a gold-like appearance. Brass is a metallic alloy that is made of copper and zinc. In antiquity, it was polished and used for mirrors. It is extensively used today for military and police insignia and badges, as well as many industrial applications. It is also used for architectural features on buildings such as domes, where it gives the appearance of gold when illuminated by the sun.  Our brass plating  is indistinguishable from solid, foundry-cast brass.

Copper. We plate  a few plaques each year with copper. Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal that has a reddish-orange color. Copper is  constituent of various metal alloys, such as sterling silver used in jewelry.  Copper was discovered in the Middle East around 9000 BC, and is the oldest metal discovered by man. It was the first metal to be smelted from its ore, c. 5000 BC, the first metal to be cast into a shape in a mold, c. 4000 BC and the first metal to be purposefully alloyed with another metal, tin, to create bronze, c. 3500 BC.Copper was named after  Cyprus, the  principal mining place in Roman era (Cyprium), Copper is mentioned in the Bible: "Men know how to mine silver and refine gold, to dig iron from the earth and melt copper from stone" (Job 28:1–2). Copper is used in buildings, usually for roofing, and oxidizes to form a green verdigris (or patina).The Statue of Liberty contains 179,220 pounds of copper.Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Excluding expense and weight,  Copper plating  is indistinguishable from solid cast copper.

Nickel-Silver. We use Nickel-silver, sometimes called German-silver, to plate many plaques each year. Nickel-silver is a copper alloy with  60% copper, 20% nickel and 20% zinc. Nickel silver is named for its silvery appearance, but it contains no elemental silver. The name "German silver" refers to its development by 19th-century German metalworkers in imitation of the Chinese alloy known as paktong (cupronickel). Nickel-silver was first known and used in China. During the Qing dynasty, it was "smuggled into various parts of the East Indies", despite a government ban on the export of nickel silver. It became known in the West from imported wares called paktong (Cantonese), literally "white copper", for which the silvery metal  was used to imitate sterling silver. The earliest European mention of paktong occurs in the year 1597. In 1823 a German competition was held to perfect the production process: the goal was to develop an alloy that possessed the closest visual similarity to silver.  In 1830 the German process of manufacture was introduced into England, while exports of paktong from China gradually stopped. That is why today the alloy has lost its original name (paktong) and is generally known as German silver. After 1840, the development of electroplating caused nickel-silver to become widely used. It formed an ideal, strong and bright substrate for the plating process. It was also used un-plated in applications such as cheaper grades of cutlery. With our cold-sprayable plating application,  Nickel-Silver is indistinguishable from foundry-cast nickel-silver and is an impressive silvery metal veneer on our High-Density-Urethane (HDU) plaques.

Aluminum.  Many of our plaques are plated with aluminum, which gives them a  shiny, silvery  finish when polished and buffed. Aluminum is more reflective of light than nickel-silver, which has a duller, more diffuse finish. Aluminum is the 13th element,  the most abundant metal in the Earth’s crust. It has a low density and is lightweight,  strong and corrosion resistant. Aluminum was once considered more valuable than gold, Napoleon gave his most honored banquet guests aluminum utensils, while the others were given gold utensils. Aluminum is used extensively in buildings and architectural features.The apex of the Washington Monument is made of aluminum. Our aluminum plating possesses all the characteristics of foundry-cast aluminum, including texture and finish, and is indiscernible  when compared to the solid metal.

24K Gold Leaf Gilding. We gild by hand the surfaces of usually some but sometimes all areas of a plaque with 24K  gold leaves, and then burnish the surface, which is a technique used by ancient Egyptians 3000 yrs ago (King Tutankhaman's artifacts were gold-leaf gilded) and used for thousands of years on architectural features and objects d'art in palaces and cathedrals. Gilding consists of applying small (3.5 inches x 3.5 inches)  extremely thin rectangular  leaves of pure gold to the surface to the plaque's  surface using sizing. Excess leaf is cut off, and a protective clear coat is applied over the leaves. We often gild V-carved engraved letters, borders and artwork in wood or HDU substrates with 24K gold-leaf, leaving the backgrounds stained or painted. This technique is available for both 3-D and 2.5-D plaques. Examples of gold  gilded plaques are shown in Fig 4 above, left side.

Silver Leaf Gilding. We gild by hand the surfaces of some areas of a plaque with pure (99.6%)  fine silver leaves, and then burnish the surface, in a manner very similar to that of gold leaf described above.  We can gild backgrounds,  V-carved engraved letters, borders and artwork in for either wood or HDU substrates, or the entire plaque. This technique is available for both 3-D and 2.5-D plaques. Silver leaf must be sealed with two coats of  Matthews polyurethane acrylic clear coat, or it will tarnish due to oxidation.  An example of a silver gilded plaque in shown in Fig. 4 above, second plaque from the left.

 Aluminum Cladding & Aluminum/Steel Sheet Signs. We cut out patterns of letters, borders or artwork from very thin sheets of aluminum, and mount them on wood or HDU  text or art raised above the backgrounds,which has been carved out by our CNC router. We also cut out aluminum and wrought iron outline signs from 1/8 to 1/4 inch thick metal sheets with our water jet cutter, sometimes cutting out openings for either the letters or the backgrounds around the letters or art.This technique is available for  2.5-D plaques only (not 3-D). An example of an aluminum-clad plaque is shown in Fig. 4 above (second plaque from right).

Solid Bronze and Aluminum. We also offer solid cast and precision tooled custom and standard bronze and aluminum 2.5-D and 3-D  plaques, which we get wholesale from a professional foundry.   These are the only plaques we do not fabricate in-house; we design them but have a foundries  who we partner with which actually  cast or machine them. For casting, they first require a 2.5-D or 3-D computer design, which is used to drive a CNC router to carve a foam replica. This replica is then used to create a sand mold,  and molten bronze or aluminum is then poured into the mold. After the plaque is cooled, it has any rough edges ground off, and it is  polished and coated. Background areas can be given a patina or can be painted. An example of an cast bronze plaque is shown in Fig. 4 (right side). You can also order precision tooled bronze, brass, or aluminum 2.5-D plaques. These are precisely machined out a sheet of bronze, brass or aluminum, and can have a variety of shapes, custom artwork, flat relief levels, surface finishes, and colors.

 We sometimes combine two of the above techniques together on the same plaque (but in different areas), i.e, we often gold-leaf a small area of a brass-plated plaque to hi-lite  artwork  or raised text, so as to provide visual interest in key areas of the plaque. Many of our original and creative 3-D designs are true works of art.
