Aluminum Sign Terminology and Spec Information - HIP, EGP, VIP Diamond Grade

Posted by Miles Horn on 8th Sep 2016

If you live on a private road you can get general specs from your county website about street sign requirements. Sign shops can create street signs to match the coloring and specifics of your county. Just provide the spec sheet you obtained from the county, what you would like the sign to read, and payment information. Those who live on private roads have more options available to them. Though you may want the color and lettering to match what your county has, you really aren't bound by the county spec requirements. It just has to say "Private Road" on the sign.

If you would like something custom then often times there are more specifics needed then you would think.  Of course you need length and width, but you also need lettering size and font size.  There are thicknesses of aluminum signs too.  Many counties mandate .080 aluminum on street signs so that they will last as long as possible, but it is more expensive.  You will pay less for .063 aluminum and it will still stand the test of time.

There are a lot of different background options for signs.  You can get E.G.P. (Engineer grade prismatic), H.I.P. (High intensity prismatic), or V.I.P. diamond grade (Visual Impact Performance).  All of the above signs are reflective.  H.I.P. has almost like a rainbow color effect as your headlights pass over it, and it really pops out at drivers during the daytime as well as night.  The V.I.P. diamond grade is basically the best possible and is used in high traffic areas where you need the sign to be reflective for short and long distances. You can also get a vinyl stickers over top of an aluminum sign if you have complex images with lots of colors in them.

There are different lettering options too.  You can get vinyl lettering put over top of whatever background you choose.  Usually vinyl lettering is black but there are other color options.  Vinyl lettering tends to be the most cost effective option.  Film instead of vinyl is another option .  This process creates a very cohesive appearance in your sign.  If you were to request a white E.G.P. background with blue film over it this is how the process works.  The sign shop will take the image and lettering you provide, and have that perfectly cut out of the film that is adhesive on one side.  The film is then put over top of the white background sign making your letters and imaging white, and the rest of the sign is now blue.

You can also get graffiti guard put over signs if they are in areas that tend to be vandalized.  This guard makes it easier to clean off a sign without damaging the lettering or the film on the sign.  Of course every little option costs a little more, and costs vary depending on the sign shop you go to.  It is $6 per sign to get graffiti guard at Sierra Safety Company. 

The above options are the spec information sign shops would ideally like you to have figured out when you come in or call, and ask to have a sign made.  They will provide you with a quote, and if you are happy with the figure then you provide payment.  The sign shop will provide one proof for you to make minor adjustments to if necessary.  If you find any errors you can request certain things be altered.  The sign is then manufactured and made ready for you to come pick up.  This is the basic information you need to get exactly what you want out of your signage experience.  If you have any questions please ask us!
