What Material are HDU Letters Made of?
They are made of a specialized polyurethane foam that is formulated to be extremely dense and resistant to weather and moisture. HDU foam is created using a specialized manufacturing process that involves injecting liquid polyurethane ingredients into a mold. The resulting foam is then subjected to extreme temperatures and pressure, which increases its density and stability. HDU foam is known for its dimensional stability, meaning it resists warping, cracking, and splitting over time. It is also easily moldable and can be machined, carved, and routed into any shape or size desired. And, HDU foam is environmentally friendly, as it is ozone-safe, non-toxic, and non-CFC.
Mounting Options
1. Flat Mounting to the Building Wall: HDU letters may be directly mounted to the building wall using studs or nails. Concrete nails are suitable for masonry walls, while galvanized nails work well for wood walls.
2. Standoff Mounting: HDU letters may be mounted with standoffs, which create a space between the letters and the mounting surface. This adds a dimensional effect and enhances the visibility of the signage.
3. Hanging Mounting: Another option is to hang HDU letters using hooks, brackets, or chains. This method allows for easy installation and removal, making it convenient for indoor signage or temporary displays.
4. Sculptural Mounting: HDU letters may be mounted in a sculptural arrangement, creating an artistic and eye-catching display. This technique involves mounting the letters at different angles and heights to create a visually appealing composition.
5. Monument Mounting: For ground-level signage, HDU letters may be mounted on a monument or base, providing a sturdy and professional installation. Monuments can be constructed from materials like concrete or metal, depending on the desired aesthetic and durability.
These mounting options give flexibility in choosing the most suitable method for displaying HDU letters based on the location, purpose, and design preferences.
