Loose HDU letters
Individual letters and numbers cut from approved vector artwork for mounting to sign faces, walls or prepared substrates.
Custom-routed HDU letters, numbers, logos and raised sign components for sign shops, brokers and commercial buyers. Order one custom set or repeat production sets, shipped raw, primed or finished for installation by your local sign professional.
HDU is a practical material for custom sign letters because it machines cleanly, accepts detailed profiles and provides visual depth without the weight of many solid materials. We manufacture custom foam letters from exterior-grade HDU sign board—not temporary event foam—and prepare the components for the completion level specified in the quote.
Letters may be cut as individual characters, connected scripts, logo shapes, raised overlays or complete sets for a sign face. Each project is reviewed for cap height, minimum stroke, counters, thickness, edge treatment, finish and mounting requirements before production begins.
Individual letters and numbers cut from approved vector artwork for mounting to sign faces, walls or prepared substrates.
Applied lettering and logo shapes that add depth to monument faces, entrance signs, directional signs and identity panels.
Multiple routed components assembled to create borders, emblems, shadows, dimensional graphics and contrasting face treatments.
Approved letter and logo sets labeled by location, elevation or phase for franchise, property and multi-site sign programs.
Raised lettering and a custom oak-leaf logo create depth while keeping the completed sign manageable for shipping.

Shop photographs help confirm the layering, spacing and finish before a completed sign is packed for shipment.
Review artwork requirements →HDU is uniform and has no knots or natural grain direction, which makes it useful for routed letter shapes, decorative edges and custom logos. It is also lighter than many solid substrates, helping reduce handling and shipping weight. The correct design still matters: narrow strokes, sharp projections and small interior counters can be fragile in any routed material.
For exterior work, the coating system must cover the face, sides and exposed edges as specified. Mounting hardware and adhesive selection depend on the receiving surface, letter size and local conditions. We manufacture the components; the installer remains responsible for the wall, structure, fasteners, sealants, permits and code requirements.
| Decision | What it changes | Information to send |
|---|---|---|
| Letter height and overall width | Controls visibility, fragility, machine layout and shipping size. | Cap height, overall logo size or a scaled drawing. |
| HDU thickness | Changes projection, shadow, edge visibility and fastener length. | Requested thickness or the visual depth you are trying to create. |
| Finish level | Determines whether the set ships raw, primed or fully painted. | Face and side colors, sheen and approved paint codes. |
| Mounting plan | Affects stud preparation, patterns, spacers and back-side machining. | Wall or panel substrate and the installation method planned by your installer. |
| Applied faces or layers | Adds contrast, surface detail and additional assembly steps. | Separate artwork layers and the exact face material requested. |
AI, EPS, SVG, DXF or a clean vector PDF is preferred. Fonts should be converted to outlines.
Provide cap height, overall width, thickness, quantity and the shipping ZIP code.
We check narrow strokes, small counters, sharp points and unsupported pieces before quoting.
Confirm HDU thickness, colors, applied layers, edge details and mounting scope.
Components are routed, edge-prepared, primed or painted according to the approved quote.
Sets are protected for shipment and may be labeled by location or installation elevation.
A photo or logo is enough to start a conversation, but a production quote needs dimensions and completion requirements.
HDU sign letters are dimensional letters and logo components machined from high-density urethane sign board. They are lightweight, do not contain wood grain, and can be routed, primed and painted for sign applications.
Yes, when the requested foam-letter product is HDU sign board. These are rigid, routed sign components rather than lightweight event-display foam letters.
Yes, exterior-grade HDU is commonly used for outdoor sign letters when the design, finish, mounting method and installation are appropriate for the location.
Large letters can be reviewed from vector artwork or a scaled drawing. Size, thickness, stroke width, shipping dimensions and installation planning all affect the production method.
Yes. Face and return colors can be quoted separately. Provide approved paint codes and identify which surfaces require each color.
A full-size pattern, stud locations, spacers or other mounting support may be quoted when the artwork and installation plan are known.
The standard service is manufacturing, protective packaging and nationwide shipping. Installation is performed by the buyer or a qualified local sign installer.
Include the overall dimensions, quantity, face and side colors, mounting plan and delivery ZIP. We manufacture and ship custom letter sets nationwide; installation is handled by the buyer or a local sign professional.
