Why Choose Us?

Energy Efficient LEDs

Light Emitting Diodes (or LEDs) have really advanced the sign market in many ways. For the customers of our commercial sign company, it provides up to 100,000 hours of burn time and uses up to 80% less power than fluorescent bulbs – reducing power and maintenance costs.

Sun-Resistant Acrylics

The sun can cause the most damage to a sign, which is why it is important to know what kind of acrylics look the best and last the longest. Don’t worry we already did the research!

Durable Construction

We manufacture custom signs using the best materials available at our commercial sign company! This will ensure that your new sign will not rust, corrode or fall apart. If installed outside, it will withstand the wind loads typically seen in California.

Great Advertising

They might seem expensive at first, but signs are actually one of the best advertising investments you can make! Without a sign, many won’t know where you are or what you offer – and the quality of the sign can be perceived as a reflection of the quality of services/products you offer.

Automotive Grade Paints

Our two-step paint process is used only with the best paints that have a 10+ year life. Some colors can fade faster than others, and direct sunlight can cause damage. That’s why high quality paints are so important to helping protect your sign and keep it looking good.

5 Year Warranty

We know a quality-made sign can be a big investment and decision to make, which is why we offer a 5 year warranty on our signage. You can be confident that your new sign will perform the way it’s supposed to – and you have our customer care team on your side.
