What Material?

Thursday, October 06, 2011

Did you ever wonder why a sign you saw looked so bad? Was it rusty or grubby looking? Were there streaks or stains in certain areas? Many times that is the result of poor material selection for either the substrate, the structure or the finish material used. In this post we'll focus a little on the materials used in the substrate and structure - and why some materials are better than others when designing a business sign.

The material used in the structure of a business sign is most often controlled by the size and the cost. For smaller post and panel signs, they are often wood posts, with either wood or aluminum sign panels. We use vinyl components as often as possible because they do not require maintenance and they maintain their good looks for years. Often, if the strength of wood is required, we can use a vinyl post to slide down over the wood post creating a sleeve that will maintain that bright look for years.

But here is where many people make a mistake: Let's assume we used a vinyl post sleeve over wood, and we used an aluminum panel for the sign itself. How do you fasten the panel to the post? The best way is to design the system to interlock and use no fasteners. But when screws are required, you have to choose the right type. Use a standard steel screw that may be coated, and over time you'll watch your sign corrode away. The aluminum - being more reactive than the steel - will become a "sacrificial anode" and it will begin to corrode, protecting the steel screw. For those who might be familiar with boat motors, this is the same principal that applies when outboard engines require a set of "zincs."  These will corrode away, protecting the aluminum engine and lower units.  

The point here is that the choice of materials can have a distinct impact on the appearance of your sign over time - as well as the amount of maintenance required. Choose the wrong materials, and not only will you see deterioration on the sign, but your customers will see that deterioration as an impression of your company.

In upcoming posts, we will cover some other sign materials that can be used or not used in specific environments that will have an impact on your signage.
