LetterForm®

Our unique LetterForm fabrication techniques have been giving our customers many advantages:

Increased Profitability With relatively few competitors able to produce Trimless LetterForm letters, your sign business can command a higher price for these attractive, premium quality letters that are now being specified by companies such as Starbucks, Nissan, Walmart, and Hyundai’s Genesis brand. 

Exclusivity SDS Automation’s exclusive LetterForm Timeless channel letter system is only available to SDS Automation customers. The exclusivity of this product provides the ability to dramatically increase profit margins compared to traditional, comoditized channel letters. 

High Visual ImpactTrimless LetterForm delivers a highly customizable appearance and the ability to fabricate unique, high-end designs such as front lit, side lit, edge lit, halo, lit, or combinations of various illumination techniques.  LetterForm coil is available in 4 different heights (letter depths): 37mm, 60mm, 81mm, and 100mm as well as 6 different colors and finishes: gloss black, satin black, gloss white, silver brushed aluminum, primer coated, and polished stainless steel.

Longer Lasting Signage – Not only does our adhesive-sealed Trimless technology achieve a cleaner, more contemporary look, it produces longer lasting letters by eliminating the unsightly plastic trim cap which is usually the first channel letter component to fade, crack, peek, or fail completely. 

More flexible material – The polymer ridge on LetterForm makes that material more flexible for smaller, more challenging designs.

A Variety of Sizes and Finishes – The variety pre-finished colors available saves time and money by eliminating the costly, multi-step prep and painting process. LetterForm coil is available in 4 different heights (letter depths): 37mm, 60mm, 81mm, and 100mm. 6 different colors and finishes are also available: gloss black, satin black, gloss white, silver brushed aluminum, primer coated, and polished stainless steel. 

Simple Installation and Repair Our patented EasyClips simplify the installation of Trimless LetterForm letters.  Simply secure the back panel of your letter, with EasyVlips attached to the wall or raceway, and the face/return assembly securely snaps into place. EasyClips are concealed from view inside the return assembly but still allow our Trimless letters to be serviced with ease.

LetterForm Strucural Support

Important

Interior Signage

  • Maximum allowable spacing between structural supports is 12 linear inches as measured along the return.
  • A minimum of four (4) structural supports per letter must be placed on the longest segments of all letters measuring 16” or greater in overall height or width, whichever is greater.
  • Single supports must be used along curved sections of all letter returns.
    Groups / blocks of 2-3 connected supports must be used along straight sections of all letter returns.
  • Maximum height or width of any individual letter must not exceed 42 inches. Screws must be used to secure the return to the clip. A minimum of two screws (2) per letter must be used.
  • Maximum allowable spacing between clips cannot exceed 12 linear inches as measured along the perimeter edge of the back panel.
  • A minimum of 4 clips per letter are required.
  • Clips must be located at the top, bottom, left and right sides of each letter or shape.
  • Clips and supplemental supports cannot fall in line with each other and must be staggered, otherwise they will interfere with the assembly of the return to the back panel.

Exterior Signage

  • Maximum allowable spacing between structural supports is 10 linear inches as measured along the return.
  • A minimum of four (4) structural supports per letter must be placed on the longest segments of all letters measuring 12” or greater in overall height or width, whichever is greater.
  • Supports should be placed at the top, bottom, left and right sides of a letter or shape wherever possible.
  • Single supports must be used along curved sections of letter returns.
  • Groups / blocks of 2-3 connected supports must be used along straight sections of letter returns.
  • Maximum height or width of any individual letter must not exceed 38 inches.
  • Screws must be used to secure the return to every clip.
  • Maximum allowable spacing between clips cannot exceed 12 linear inches as measured along the perimeter edge of the back panel.
  • Clips must be located at the top, bottom, left and right sides of each letter or shape.
  • Clips and supplemental supports cannot fall in line with each other and must be staggered, otherwise they will interfere with the assembly of the return to the back panel.

All Signage

  • Clips and supports can not be added to the same location. They must be offset slightly.
  • Single supports are used to support arcs. Blocks of 2-3 supports are recommended to support straight sections.
  • Mounting locations for the supports must first be cleaned with alcohol.
  • Supports are attached to the return and the inner surface of the face material using SDS recommended CA glue.
  • After applying the glue to the return, apply the the support(s) to the surface and apply proper force in the vertical direction to spread the adhesive uniformly. Mist the glue with accelerator spray.

LetterForm Seam Closures

These are our recommendations for joining your returns:

  • Use a bridge extending a minimum of 2″ on both sides of the join.
  • The bridge should span the full height between the ribs to minimize light leakage.
  • You should use structural adhesive to glue the bridge to the return.
  • The bridge should be reinforced with four rivets.  Using only two rivets may allow the join to twist.
  • If you join at the corners, all of the same applies, but your bridge will be angled 90 degrees.

Primer Coated LetterForm

LetterForm is the proprietary aluminum return material from SDS Automation that is changing the way channel letters are being made. It has a cleaner appearance to traditional trim capped letters, making it the preferred choice in many applications. Previously, it was only available in stainless steel or painted black or white, which meant that if you wanted a different color, the outside surface would have to be prepped for painting. Now, with our new Primer coated coil, the prep is already done, saving you time and money.

The outside surface (shown above) is coated in an off-white primer that has a matte textured, paint-ready finish. While the inside surface (shown below) is painted with a gloss white enamel to increase reflectivity and then fitted out with PVC strips for mounting the face and backing plate.

Primed LetterForm is currently available in two heights, 60 and 100 mm (approx. 2.375″ and 4″ tall) and is in stock, ready to ship. Of course, LetterForm is designed to work with our benders so you must have an Eco, Super or Super ChannelBender XP to use this material. Good news! We have those in stock too.

 

Note:
Trimless letters must be limited in size and weight due to the characteristics of the material. Structural integrity can vary due to climate, temperature, surface area, and overall perimeter of the letter. SDS makes no definitive recommendation regarding maximum letter height or weight. Users may wish to consider not exceeding 30″ in height when fabricating letters with LetterForm coil. Each user is responsible for performing an independent structural integrity evaluation for each application.
