Letters - Dimensional Signs

Monday, December 13, 2010

Entrance SignSome of the longest lasting signs available are what are known as "Dimensional Letters or Signs". These may be a company name, its logo, or a combination. These letters are manufactured in a number of different ways and can be made from aluminum, stainless steel, copper alloys, or an assortment of plastics. They can be flat or they can be formed to give a greater perception of depth.

What we will focus on are flat letters or logos that are cut out of metal or plastics. When we look at metal letters that are considered "off the shelf" they can come in at least 6 different metals, and six different thicknesses and over 50 standard finishes. They can be made as small as 1/2" all the way up to 5 ft. With acrylic flat cut letters they can range from 1" to 6 ft and are available in 32 standard pigments. With either metal or acrylic they can be painted to match a PMS color that you require and custom designs can be handled.

When fabricating these letters there are a number of ways that they can be manufactured. The letters can be routed out using a CNC (Computer Numerically Controlled) router or mill, they can be cut using a laser, or they can be manufactured using water jet cutting. One nice thing about any of these methods is that all the scrap that is generated is put back into the system and recycled to use later. Modern manufacturing methods have reduced the lead time for these types of letters and also improved their quality.
