Channel letters are one of the most popular types of building signage used by businesses today. They are bold, easy to read, and highly customizable. Whether illuminated or non-illuminated, these signs help businesses stand out and attract attention.
At SignWorks, we have completed many channel letter projects across the San Francisco Bay Area. From design to permitting to installation, our team helps clients create signage that fits their brand and meets city requirements.
What Are Channel Letters?
Channel letters are three-dimensional signs made from metal and acrylic. Each letter is individually formed and mounted to a building. These signs can be lit or unlit depending on the client’s needs.
Common Features:
- Custom shapes and fonts
- Durable materials like aluminum and acrylic
- Options for lighting or non-lighting
- Mounted directly to buildings or raceways
Channel letters are often used for storefronts, office buildings, and retail centers because they are both professional and eye-catching.
Illuminated Channel Letters
Illuminated channel letters are designed to shine day and night. They use LED lighting inside or behind the letters to create visibility in low light conditions.
Types of Illuminated Channel Letters:
- Front-Lit Letters: Light shines through the face of the letter
- Halo-Lit (Reverse Lit): Light glows from behind the letter
- Combination Lit: A mix of front and halo lighting
Benefits of Illuminated Signs:
- Increased visibility at night
- Strong brand presence
- Clean and modern appearance
- Great for high-traffic areas
Non-Illuminated Channel Letters
Not every project requires lighting. Non-illuminated channel letters offer a simple and cost-effective option while still providing strong branding.
Benefits of Non-Illuminated Signs:
- Lower upfront cost
- Easier permitting in some cities
- Clean and professional look
- Ideal for well-lit areas or office parks
These signs are often used in business parks, warehouses, and locations where lighting is not necessary.
The Design and Permitting Process
Before fabrication begins, every channel letter project goes through a design and permitting phase. This is an important step, especially in cities across the Bay Area where sign regulations can be strict.
Design Phase Includes:
- Logo layout and sizing
- Color matching
- Material selection
- Placement on the building
Permitting Phase Includes:
- Submitting drawings to the city
- Following local sign ordinances
- Working with permit expeditors if needed
- Revising plans based on city feedback
At SignWorks, we guide our clients through this process to help avoid delays and keep projects moving forward.
