Product Line 9 - Custom Rugged and Durable Engraved HDPE Outdoor Signs (STYLE and PRICE CODE 1.5.1)

Welcome to our photo Gallery 9 which shows examples of our long-lasting, low maintenance, rugged engraved (incised) HDPE signs, referred to in this website as Product Line 9. Approximate prices for Product Line  9 signs & plaques are given in Line 1.5.1 in Fig 4B on our  Prices & Design Options page. 

If you have just entered our website and you want an overview of our company and all our products or other informational web pages such as our  Home page, you can view these by clicking on a title in the  gray box in the upper left margin. Fifty different  Product and Application photo galleries can be viewed by using the slider to scroll down that gray box and clicking on a numbered title.   If you are using a cell phone, you can click on the 3 red bars on the top right of your screen to see this menu.

The custom signs in this photo Gallery 9 have styles that range from  commercial to rustic. We can also incorporate your design concepts, different font styles, maps,  logos, and other artwork into the design of your Color-Core or  Plastic Wood  & Reinforced Fiberglass  HDPE sign. Most of our designs shown on this website  are the result of a collaboration between our designers and the customer. We can turn nearly any artwork into a long-lasting, rugged  custom engraved HDPE  sign.


We make many of our rugged , low-maintenance outdoor signs where 3-D or 2.5-D multi-level raised relief is not required by  using a High Density Polyethylene (HDPE) material called King ColorCore®. It is a versatile multi-color engravable high-density polyethylene sheet,  either 0.5" or 0.75" thick,  with three layers of contrasting colors which is used to make durable,  color-fast  signs with engraved text , borders and artwork.  It is a superior homogeneous sheet, a product of a unique state-of-the-art continuous process called Polyfusion, and manufactured to the highest standards in the industry. King ColorCore® has a matte finish on both sides of the sheet.

It is environmentally stabilized to withstand the harshest outdoor conditions. ColorCore® will not rust, delaminate or rot when exposed to UV, humidity or water.  ColorCore® is made with high-impact-resistant polymer to handle more abuse than conventional sign materials.  Its thin cap layers and bright primary colors make it ideal for signage for marine, playground, golf course, traffic signs,  and recreational applications. The polymer sheet never needs painting or refinishing because the color is impregnated into the resin of the plastic.. HDPE carves  like HDU or wood and it is easy to fabricate using common woodworking tools and techniques. The material is easy to engrave and machine with our CNC routers, as the cap is approximately .050” thick.

 ColorCore's® thin cap layers (approximately 10% of the thickness on each side) and bright primary colors (approximately 80% of the core) make it the ideal material for signage, marine, playground and other recreational applications.

Scratch resistant ColorCore® is UV stabilized to resist deterioration in harsh outdoor environments as well as marking by pens, markers and spray paint.  ColorCore® can be cleaned easily with regular household cleaners.

ColorCore® sheets are  available in several thicknesses and a rainbow of matched colors, as shown in the figure below.. Custom colors are available by custom order. Other colored resins  can be a used to fill in the engraved areas, so that text or art can be colors different than the middle layer. Photos M9020, M9050, M9120 and M9130 below shows signs where this was done. 


We also make fiberglass reinforced plastic wood HDPE signs and posts.  Like Color Core HDPE, these are engraved.  Plastic wood boards are typically 1" to 2" thick, compared to 0.5" and 0.75" thickness for Color-Core. They do not come in large sheets like Color-Core, but come in separate boards up to 12" wide. Plastic wood boards and posts are homogenous, and do not have a center section with a different color like Color-Core. They are most suitable for natural and rustic applications, such as parks, campgrounds, trails, and other areas where a natural wood look is desired. They offer major advantages over wood, however, because they do not require maintenance or repainting. These signs and posts do not rot, split, rack or fade from UV. They are completely waterproof. They are stronger than wood, when structural designs that use internal fiberglass reinforcement are selected. Plastic wood boards are often used for decks, outdoor park benches, and marine applications. 

 Plastic wood signs and posts  are available in a variety of colors that eliminates the need to stain or paint  but most often customers select brown or tan to resemble real wood.

Benefits of reinforced structural grade plastic wood are:

  • 100% recycled HDPE plastic, fiberglass reinforced
  • Superior weatherability, colorfastness & durability, UV stabilized
  • Authentic wood look boards have a textured surface to simulate wood grain, surface will show slight weathering with age
  • Impact & scratch-resistant, termite proof, waterproof
  • Will not delaminate, chip, split, crack , splinter rot, or swell


Made from fiberglass reinforced recycled high-density polyethylene (HDPE) plastic, structural grade plastic lumber is a great alternative to treated wood. It is made with recycled plastic that typically comes from milk jugs and detergent bottles and is an ideal material to use for all types of heavy commercial infrastructure projects. Our structural grade plastic lumber does not contain wood,  It is made from a blend of recycled high-density polyethylene (HDPE) and wood dust/fibers. Structural grade HDPE contains fiberglass strands embedded in the HDU in the interior of the boards or posts for extra strength

Signs and posts have maximum strength and rigidity with the use of fiberglass reinforced plastic. It is the preferred material by users looking to replace wood so maintenance is not required. It is often used for decks,  park benches and mailbox posts. It is smooth and does not crack, check or splinter. It offers a clean and aesthetically pleasing look. Signs are made up of individual boards that can mounted close together on a post or between posts, as shown in Fig. 4 above.  Board sizes are  2 inches  and come in widths of 2, 4, 6, 8, 10 and 12 inches and lengths from 6 ft to 24 ft.   Square cross-section post come in sizes of 2 x 2, 4 x 4, 6 x 6, and  8 x 8  inches.     

Like Color Core signs, plastic wood HDPE signs can be engraved in either a flat bottom (U-profile) or V-profile. Artwork (e.g .arrows or logos), text and borders can be engraved into the plastic wood boards or posts. These engravings are filled with various colors of epoxy resin, because unlike Color Core, which has a different color material in the middle, plastic wood is homogeneous and is the same color throughout so engravings  would be difficult to read without a different color epoxy resin.  For brown plastic wood, white, yellow or light tan colored epoxy is usually used for maximum text visibility.                                                                               


Add  appeal to your home while displaying your address using a Mayne Woodhaven Sign Post. This dramatic post brings an architectural look to your yard, capturing the attention of passers by. A 56" tall, rectangular column offers classic lines, enhanced by dual inset panels on each side of the item. A lengthy arm extends from the main unit, with an inward curving arch at the top for movement and dimension. Its dimensions are  24"L x 8"W x 56"H. The white or black color of the post blends with any surrounding easily, and the dramatic arm attaches to the piece in moments. Made from durable, molded polyethylene (HDPE) , Mayne HDPE molded sign posts  will remain lovely with little maintenance. Ultraviolet inhibitors within the product help keep the white color vivid, 

This arm can accommodate a custom address sign up to 14" wide. A 4" x 4" plastic wood HDPE post needs to be inserted  into the hollow column to add stability, and placed two feet into  ground for strength.  This product, like all our products, is made in the USA. It has a fifteen year limited warranty. An address or property name sign (which can be Color-Core, HDU or wood) , the internal plastic wood HDPE 4"x4" post, and mounting hardware can be purchased  from us.
