Bridge height signs play an important role. They inform boaters how much clearance they have from the water to the underside of the bridge at all tides.
Unless it’s obvious whether or not there’s enough vertical room to travel under a certain bridge, boaters refer to its bridge height sign.
These signs are crucial – especially in areas like Newport Beach.
With its inland waterways harboring more than 9000 boats, the City of Newport Beach California is one of the largest recreational boat harbors on the western U.S. coast.
That’s why Newport Beach teamed up with Electromark to create long-lasting bridge height marker signs that would be up to the task.
Like all outdoor identification, bridge height signs face potential deterioration. These signs are submerged in fluctuating tidal seawater levels every day.
In addition to being exposed to sea water, these signs are also exposed to UV damage and other extreme outdoor weather conditions.
In addition to replacement cost, given the unique location of bridge height signs, the tedious process of replacement makes a long-lasting solution the preferable choice.
Newport Beach’s prior solution wasn’t up for the task and fell victim to deterioration.
As you can see in the picture to the left, the colors had faded, making the sign unreadable.
Without readable bridge height signs, boaters can potentially face fines, boat damage, and bodily harm.
Electromark delivered a durable sign solution that won’t delaminate. With our state of the art PermaGrave™ material, the graphics are engraved into the material, making them part of the material itself.
PermaGrave is a tough plastic that will withstand the corrosive effects of seawater.
PermaGrave was the perfect solution for Newport Beach and is expected to last 20+ years in this application.
When your application demands durability and longevity, PermaGrave can deliver the performance you need.
PermaGrave is available in thicknesses from 0.055” to 0.75”, providing thinner gauges that will conform to curved surfaces, to thicker gauges that provide the rigidity and strength necessary for large signs and demanding applications.
